Secure Digital Transactions

𝗪𝗵𝗮𝘁 𝗛𝗮𝗽𝗽𝗲𝗻𝘀 𝗪𝗵𝗲𝗻 𝗬𝗼𝘂 𝗧𝗮𝗽 𝗮 𝗖𝗮𝗿𝗱? It's an every day part of life. You tap your card at the store, and within about a second, your payment is accepted. But what actually happens behind the scenes is one of the most complex, high-speed digital processes in finance Let’s break down the process👇 ___ 𝗧𝗮𝗽 𝘁𝗼 𝗧𝗲𝗿𝗺𝗶𝗻𝗮𝗹 When you tap an NFC-enabled card or digital wallet: ▪️Your card transmits encrypted payment credentials (EMV chip/ tokenized PAN) ▪️In the case of digital wallets, the credentials are actually network tokens ▪️A dynamic cryptogram is generated for that single transaction This all happens in milliseconds 𝗧𝗲𝗿𝗺𝗶𝗻𝗮𝗹 𝘁𝗼 𝗔𝗰𝗾𝘂𝗶𝗿𝗲𝗿 The terminal packages that data and sends it to the payment gateway, processor or acquirer. Think Adyen, Stripe, Fiserv They: → Encrypt and normalize the payload → Apply merchant-level logic (MCC checks, velocity rules) → Forward the request to the card network 𝗔𝗰𝗾𝘂𝗶𝗿𝗲𝗿 𝘁𝗼 𝗖𝗮𝗿𝗱 𝗡𝗲𝘁𝘄𝗼𝗿𝗸 The networks, like Visa, Mastercard, & American Express route the request to the right card issuer They also: → Run network-level risk rules → Check for blacklisted PANs or bad IPs → Apply token domain checks and card controls 𝗡𝗲𝘁𝘄𝗼𝗿𝗸 𝘁𝗼 𝗜𝘀𝘀𝘂𝗲𝗿 Card issuers like Chase, Barclays, or Nubank make the final call: ✔️ Does the card exist? ✔️ Is there enough balance? ✔️ Are fraud rules triggered? ✔️ Is the MCC or country blocked? If approved, the issuer generates an authorization response, which travels back to the merchant and end user (you) ▪️Total round trip: ~300–500 milliseconds 𝗜𝗳 𝗜𝘁 𝗙𝗮𝗶𝗹𝘀… → The terminal may retry with fallback to chip → Acquirers can route to backup PSPs → Network tokenization allows retries without exposing PANs → 3DS or step-up auth may be triggered for risky CNP transactions 𝗪𝗵𝘆 𝗜𝘁 𝗠𝗮𝘁𝘁𝗲𝗿𝘀 𝗳𝗼𝗿 𝗠𝗲𝗿𝗰𝗵𝗮𝗻𝘁𝘀 ▪️𝗘𝘃𝗲𝗿𝘆 𝗺𝗶𝗹𝗹𝗶𝘀𝗲𝗰𝗼𝗻𝗱 𝗺𝗮𝘁𝘁𝗲𝗿𝘀 → Delays lead to drop-off and cart abandonment ▪️𝗙𝗮𝗹𝗹𝗯𝗮𝗰𝗸 = 𝗳𝗿𝗶𝗰𝘁𝗶𝗼𝗻 → Optimizing routing can prevent retry loops ▪️𝗧𝗼𝗸𝗲𝗻𝗶𝘇𝗮𝘁𝗶𝗼𝗻 𝘄𝗶𝗻𝘀 → Enables secure, portable PAN-free flows ▪️𝗗𝗮𝘁𝗮 𝘃𝗶𝘀𝗶𝗯𝗶𝗹𝗶𝘁𝘆 = 𝗹𝗲𝘃𝗲𝗿𝗮𝗴𝗲 → Merchants with insight into auth flows can optimize for revenue, fraud, and cost 𝗙𝗶𝗻𝗮𝗹 𝘁𝗵𝗼𝘂𝗴𝗵𝘁𝘀 Paying might look simple, but it kicks off a global chain of cryptographic handshakes, trust decisions, and fraud review.

RBI recently released a discussion paper called "Exploring Safeguards in Digital Payments to Curb Frauds." I spent some time reading it over the weekend and had some thoughts. The timing is significant. CoinDCX recently launched the Digital Suraksha Network (DSN) a few weeks ago with a ₹100 crore commitment to fight digital fraud. So, we have been brainstorming internally on many of these topics and working on solutions too. Here are my thoughts on the 4 key proposals: 1. One-hour lag on person-to-person app transfers above ₹10,000: The intent is right. To break the fraudster's psychological grip on the victim. But ₹10,000 is a low bar in a country that heavily relies on UPI for everyday transactions. A higher threshold of at least ₹25,000 may be better, given that higher-value transactions carry greater financial risk. The design matters too: this delay could apply only to first-time transactions of any amount with a new recipient. Once a payee is trusted and whitelisted, repeat transfers should remain instant. That combination with first-transaction friction and whitelisting for known contacts can target fraud at the point of maximum risk without disrupting our everyday digital life. 2. Trusted person approval for senior citizens and persons with disabilities (PwD) on transactions above ₹50,000: A thoughtful safeguard for those most vulnerable to impersonation scams. The key will be implementation: making it seamless, not bureaucratic. 3. ₹25 lakh annual credit ceiling with "shadow credits" for excess: The idea targets mule accounts, but the real solution is smarter onboarding and pattern detection, not blanket credit caps. Under DSN, we are working on an open fraud intelligence API to flag suspicious patterns across institutions without freezing legitimate funds. 4. Customer-controlled kill switch for all digital payments: In my view, this is the strongest and most high impact proposal. Give every Indian the power to turn off digital payments from their account in one tap. Simple and empowering. The question of whether new accounts should be "default off" is also worth serious debate. For example, India already has a version of this. UIDAI's Biometric Lock feature on the mAadhaar app lets you keep your Aadhaar biometric authentication switched off by default. We can unlock it temporarily for just 10 minutes when we need it. RBI has the right intent. We are on the same side of this fight. Our work on DSN: a WhatsApp helpline, a fraud intelligence API, law enforcement training are all designed to complement exactly this kind of regulatory thinking. Look forward to sharing more about what we are building soon. India doesn't need to choose between speed and safety. India needs systems that deliver both. 🇮🇳🫡

80% of Financial Frauds Are Now Digital—Are We Prepared? The number of digital financial frauds skyrocketed in FY24, growing more than four times year-on-year. The message is clear: the battlefield of financial fraud has gone digital, and so must our defences. Relying on single-layered security measures is like locking your front door but leaving your windows wide open. Fraudsters are becoming more sophisticated, leveraging phishing, malware, and identity theft to exploit vulnerabilities across the digital ecosystem. Solution? 𝐑𝐨𝐛𝐮𝐬𝐭 𝐦𝐞𝐚𝐬𝐮𝐫𝐞𝐬 𝐭𝐡𝐚𝐭 𝐰𝐚𝐭𝐜𝐡, 𝐥𝐞𝐚𝐫𝐧, 𝐚𝐧𝐝 𝐚𝐜𝐭 𝐢𝐧 𝐫𝐞𝐚𝐥-𝐭𝐢𝐦𝐞. Here’s what a multi-layered framework looks like in action: ✅ 𝐁𝐞𝐡𝐚𝐯𝐢𝐨𝐫𝐚𝐥 𝐀𝐧𝐚𝐥𝐲𝐭𝐢𝐜𝐬: AI monitors real-time user behaviour—location changes, sudden high-value transactions—and triggers step-up authentication if something feels off. ✅ 𝐁𝐢𝐨𝐦𝐞𝐭𝐫𝐢𝐜 𝐀𝐮𝐭𝐡𝐞𝐧𝐭𝐢𝐜𝐚𝐭𝐢𝐨𝐧: Fingerprints and facial recognition provide nearly impossible-to-spoof ID checks, shutting down common phishing and credential attacks. ✅ 𝐃𝐲𝐧𝐚𝐦𝐢𝐜 𝐑𝐢𝐬𝐤 𝐒𝐜𝐨𝐫𝐢𝐧𝐠: Every transaction gets a risk profile. Unusual device types, odd transaction sizes, and abnormal frequencies get flagged, prompting further checks. ✅ 𝐄𝐧𝐝-𝐭𝐨-𝐄𝐧𝐝 𝐄𝐧𝐜𝐫𝐲𝐩𝐭𝐢𝐨𝐧: Even if criminals intercept data in transit, encryption ensures it’s just scrambled noise, not usable information. ✅ 𝐒𝐞𝐜𝐮𝐫𝐞 𝐀𝐏𝐈𝐬: As businesses integrate with partners, secure APIs validate incoming requests and ward off unauthorized intrusions at the integration points. 𝘙𝘦𝘮𝘦𝘮𝘣𝘦𝘳: Digital fraud isn’t going away—it’s evolving. The only way to stay ahead is to think like a fraudster while building like a strategist.

The Bybit incident highlights how even well-established platforms can face security challenges. As an industry, we must continue raising the bar to protect users and institutions alike. At Anchorage Digital, we take these five essential steps to ensure transaction integrity: Multi-person approval – Prevents single points of failure Biometric & behavioral verification – Confirms every approver’s identity  Cryptographic signature – Locks in source, destination, and transaction details Risk review – Augments human oversight with anomaly detection Hardware-enforced execution – Guarantees integrity at the final step Beyond this, programmatic, simultaneous settlement should be the standard for large transactions—spot, derivative, or lending—to reduce counterparty risk. Our Atlas settlement network enables institutions to settle directly, eliminating the need to leave assets on exchanges and reducing exposure to third-party risks. Custody matters. At Anchorage Digital Bank, our federally regulated status ensures that client assets remain bankruptcy remote—fully protected and segregated, no matter the market conditions. And industry-wide, we must empower every user with transaction simulation capabilities to assess risks ahead of smart contract interactions, swaps, approvals, or transfers. Security isn’t just about protection—it’s the foundation for crypto’s next phase of growth. We stand ready to support and wish Bybit and its customers a swift resolution.

Cybersecurity Awareness Month A thought-provoking post by Dr. Jagannath Sahoo on the growing cyber-physical risks within contactless and IoT-based payment systems. It’s a timely reminder that while innovation continues to drive convenience, it also expands the threat landscape in complex ways. Contactless payments eliminate the need for PINs and signatures, but this very convenience introduces several vulnerabilities, including: ▫️Unauthorised or fraudulent transactions ▫️Data theft and card cloning ▫️Weak points within mobile payment ecosystems ▫️Increasingly complex security protocols ▫️Limited end-user liability protection From a cybersecurity standpoint, these risks demand a proactive and layered defense strategy: 🔹 Tokenization and strong encryption should form the backbone of payment security to prevent cloning and replay attacks. 🔹 Continuous threat monitoring and anomaly detection, powered by AI and behavioral analytics, can significantly reduce fraud detection times. 🔹 Security awareness training for both consumers and merchants is crucial — many breaches exploit human error rather than technical flaws. 🔹 On the user side, disabling NFC when not in use and setting transaction thresholds are simple yet effective mitigations. As we advance toward smarter, faster, and more connected payment systems, maintaining cyber resilience is not just a compliance measure — it’s a necessity for trust in digital commerce. #CyberSecurityAwarenessMonth #DigitalPayments #IoTSecurity #Fintech #ContactlessPayments #CyberResilience #InformationSecurity

How Tokenization Works in the Flow of Transactions ? The Reserve Bank of India (RBI) first introduced device tokenisation in January 2019, followed by card-on-file tokenisation in September 2021. Mastercard's announcement that it will eliminate 16-digit credit card numbers by 2030 put the payment industry's impending move to "tokenization" into sharp relief ? Recently PhonePe Unveiled Device Tokenization Solution for Secure Card Transactions Let's understand - #Tokenization is a technology that allows for more secure payments by substituting sensitive consumer account data for a random number that is unique to each transaction – a digital token. This token contains no consumer account data, and instead is simply a map to where the bank has stored a consumer’s data within its own secure systems. Because tokens are unique to their transactions they are useless to hackers who would use them for further transactions. Tokenization means that sensitive consumer account data never travels through the retailer systems and instead stays safely locked in the banks secure infrastructure. Because the process works behind the scenes, customers won’t be required to do anything different from what they’re used to Tokenization Process : the merchant can conduct a normal transaction without seeing or storing the customer’s account number, expiration date or other information contained on a card. Since the customer’s account number is not used, hackers are left with nothing of value to steal if they break into the merchant’s computer servers. The customer’s real account number remains stored in the bank’s highly-secured virtual vaults. In #India , As of December 2024, over 91 crore tokens have been issued, facilitating more than 320 crore transactions valued at nearly ₹11 lakh crore. This growth puts stress on the shift towards enhanced security in e-commerce, with 98 % of online transactions now processed without actual card data Finnovation - Biometrics, tokenization to replace credit card numbers by 2030 ?

𝐂𝐥𝐨𝐮𝐝 𝐓𝐨𝐤𝐞𝐧 𝐅𝐫𝐚𝐦𝐞𝐰𝐨𝐫𝐤 — the newest solution by Visa to bring the ApplePay experience to all 👇 The rise of digital commerce brings immense opportunities — but also a need for enhanced security, particularly for Card-Not-Present (#CNP) transactions. This is where the Cloud Token Framework (#CTF) steps in, transforming how payments are secured across multiple devices, bringing an ApplePay-like enhanced customer experience. — 𝐃𝐞𝐟𝐢𝐧𝐢𝐭𝐢𝐨𝐧 𝐨𝐟 𝐂𝐥𝐨𝐮𝐝 𝐓𝐨𝐤𝐞𝐧 𝐅𝐫𝐚𝐦𝐞𝐰𝐨𝐫𝐤: The Cloud Token Framework (CTF) by Visa allows any connected device to become a secure channel for digital commerce, minimizing risks associated with handling sensitive payment data. It enables the tokenization of CNP transactions, ensuring a seamless, secure payment experience across devices, combining consumer identity verification (ID&V) with device intelligence. In essence, CTF creates an online payment experience binding a network token to a device and leveraging biometrics on that same device for the transaction to be initiated. An experience more secure than an in-person experience (in my opinion). — 𝐇𝐨𝐰 𝐝𝐨𝐞𝐬 𝐢𝐭 𝐰𝐨𝐫𝐤: 1. The cardholder reviews the items in their booking and proceeds to checkout 2. The cardholder enters their card details and contact information 3. The app prompts the cardholder with a verification request to designate the device as trusted for future purchases 4. The merchant or other token requestor displays a list of consumer ID&V methods available from the issuer and the cardholder selects their preferred ID&V method 5. The cardholder completes verification via the ID&V method 6. Once confirmed, the cardholder receives a message to confirm that their device is trusted for subsequent transactions 7. On the trusted device, the cardholder is prompted to verify and confirm their booking 8. Once confirmed, the cardholder’s transaction is complete. The issuer receives the required device information to perform further checks — 𝐏𝐨𝐭𝐞𝐧𝐭𝐢𝐚𝐥 𝐁𝐞𝐧𝐞𝐟𝐢𝐭𝐬: 𝐄𝐥𝐞𝐯𝐚𝐭𝐞 𝐩𝐚𝐲𝐦𝐞𝐧𝐭 𝐬𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐚𝐜𝐫𝐨𝐬𝐬 𝐝𝐞𝐯𝐢𝐜𝐞𝐬 Use consumer ID&V and device intelligence to link the consumer, cardholder and their associated devices to help prevent account takeover fraud 𝐓𝐫𝐮𝐬𝐭𝐞𝐝 𝐝𝐞𝐯𝐢𝐜𝐞𝐬 𝐢𝐧𝐜𝐫𝐞𝐚𝐬𝐞 𝐜𝐨𝐧𝐟𝐢𝐝𝐞𝐧𝐜𝐞 Enable a trusted device to minimize friction and improve authorization rates for CNP transactions 𝐅𝐮𝐭𝐮𝐫𝐞-𝐏𝐫𝐨𝐨𝐟 𝐩𝐚𝐲𝐦𝐞𝐧𝐭𝐬 Expand digital commerce use cases with an end-to-end, secure and scalable token solution The ApplePay experience was a revolution.

RBI is changing how you make online payments! Yes - from April 2026, OTP won’t be the only way to authenticate your transactions anymore. Let’s break this down 👇 👉 What’s New? The Reserve Bank of India has introduced a new digital payment authentication framework. From 2026, every digital transaction will need at least two independent authentication factors - not just the SMS OTP you use today. 👉 These factors can include 👇 ✅ Password or PIN (something you know) ✅ Cryptographic token, app token, or device key (something you have) ✅ Biometric like fingerprint or Face ID (something you are) Small-value transactions (like ₹100–₹5000) will get some relaxation for convenience. But for higher-value payments, the new system is mandatory. 👉 Why Change from SMS OTP? -} Because OTPs aren’t foolproof anymore. -} Frauds like SIM-swap, phishing, and OTP interception are rising fast. -} And sometimes, OTPs just don’t arrive when you need them most! RBI wants India to move beyond single-layer authentication - towards multi-factor, real-time, global-standard security, just like Europe’s PSD2. 👉 Key Provisions in the New Framework -} From April 2026 – Two-factor authentication becomes compulsory. -} One factor must be dynamic & unique (like OTP, cryptographic token, or biometric). -} Cross-border, card-not-present transactions get extra security from October 2026. -} Banks can even add a third layer if they feel your transaction looks risky. -} If any fraud occurs because the bank didn’t follow these norms - the bank, not you, will bear the loss. SMS OTP isn’t going away - it’ll still work. But now, you’ll also have more options like app-based tokens, biometrics, and device verification. So if OTP doesn’t arrive - your payment won’t get stuck! 👉 Impact ✅ For users - Faster, safer, and more flexible payments. ✅ For banks - A push to upgrade technology and infrastructure. ✅ For India - A big step towards a secure, global-level digital economy. This move by RBI isn’t just about rules - it’s about building trust in digital payments. A future where security meets convenience. 👉 Like if you support RBI’s new digital payment rules. 👉 Comment what you think about this big change. 👉 Repost to help others understand it too. 👉 Follow Yogesh Jangid for more such insights on hashtag #finance hashtag #business & hashtag #career

The Liability Shift in Liability Shift for Online Payments: The Importance of 3D Secure for Issuers and Acquirers. In today's digital world, online transactions are ever-increasing. Issuers and Acquirers, regardless of regional mandates, should leverage the benefits of 3D Secure 2.0. When an issuer is 3D Secure ready but a merchant is not, the liability for fraudulent transactions shifts to the merchant. This incentivizes merchants to adopt 3D Secure, ensuring protection and shifting liability back to the issuer in case of fraud. Key Features and Improvements in 3D Secure 2.0: ** Enhanced User Experience: - Frictionless Authentication: Many transactions can be authenticated without additional input from the cardholder, streamlining the checkout process. - Mobile Optimization: Designed to work seamlessly with mobile devices, providing a smoother experience for mobile transactions. ** Risk-Based Authentication: - More Data Points: Uses up to 100 data points, including device information and transaction history, for accurate decision-making, reducing the need for additional authentication steps in low-risk scenarios. ** Support for Modern Authentication Methods: - Biometrics and One-Time Passcodes (OTPs): Supports biometric authentication (fingerprints, facial recognition) and OTPs sent to the cardholder’s mobile device. ** Improved Communication: -Real-Time Decision Making: Facilitates real-time communication between merchants, card networks, and issuers for quick and accurate authentication decisions. ** Compliance with Regulatory Requirements: - PSD2 and Strong Customer Authentication (SCA): Designed to comply with regulations like the EU's PSD2, which mandates strong customer authentication for online payments. ** Exemption Handling: - Incorporates mechanisms to handle exemptions under regulations like #PSD2, allowing certain low-risk transactions to bypass additional authentication steps. ** Delegated Authentication: - Allows merchants to perform #authentication on behalf of issuers, improving the flow and speed of the transaction process. If you are an #Issuer or an #Acquirer and want to learn more about implementing #3DSecure for your #cardholders or #merchants, talk to our experts at Ren Payments by Euronet. #payments

Digital wallets are miles ahead of traditional card payments when it comes to security due to enhanced security features like tokenization, biometric authentication, and encryption - but the way they protect your data is slightly different. Here’s the breakdown: 🍎 Apple Pay:  ↳ Uses device-based tokenisation so your actual card number is never stored or shared ↳ All data is stored locally on the device in the Secure Enclave ↳ Doesn’t track your transactions or link them to your Apple ID ↳ Biometric authentication (Face ID / Touch ID) is required for each payment ✅ Merchants never see your real card details ✅ Apple never knows what you bought or where 🔐 Google Pay: ↳ Also uses tokenisation  ↳ Stores some data in the cloud, and Google may collect transaction info (which can be used to personalise services) ↳ Biometric authentication is still standard, but setup can vary by Android device ↳ Google has broader integrations which can be a convenience win but raises more questions around data use and privacy So which is more secure?  👉 Both are secure, but Apple Pay edges ahead in terms of privacy-first design and keeping your financial data out of the cloud.  👉 Google Pay is still a safe choice, especially if you're in the Android ecosystem, but just be mindful of the data-sharing trade-offs. Which one are you using and was security a consideration when you chose it?
