In the first half of 2024, £571 million was lost to card payment fraud in the UK alone, much of it driven by scams on social media. Fraud has clearly evolved, adopting more modern and sophisticated tactics. In payment, one standard governing how card data is protected, namely how it is stored, processed, and transmitted, is the PCI DSS directives. The Payment Card Industry Data Security Standard was created in 2004 and has been the backbone of payment security for nearly 20 years. This year marks a big shift. Its latest version, PCI DSS v4.0, will become mandatory in March 2025. This is the first major update in over a decade, so worth taking a closer look at the key changes. Overall, PCI DSS v4.0 focuses on critical aspects such as encryption, authentication, network segmentation, and vulnerability testing, ensuring businesses are better equipped to handle the 'modern' security threats that are increasingly sophisticated too. ◾As such one of the key changes is the introduction of a flexible compliance approach. This means merchants can choose security measures that best fit their specific needs and risks. This approach is well-aligned with how businesses today manage their security challenges. In the same way that authentication frameworks are becoming more adaptive to varying levels of risk, other security measures are also evolving to be more context-specific and scalable. ◾Another key update focuses on the Stronger Authentication framework. Multi-factor authentication (MFA) is now mandatory for all accounts accessing sensitive payment systems, including remote administrative access. Specifically, MFA is required for all accounts that interact with the Cardholder Data Environment (CDE). ◾Stronger encryption and better key management are now essential. Businesses must use modern encryption methods instead of outdated ones. They also need to improve how encryption keys are created, shared, and stored to reduce the risk of data breaches and unauthorised access. ◾Given the industry’s shift towards real-time data processing, the latest guidelines also encourage automated monitoring and the use of tools that enable businesses to detect and flag non-compliance in real time. 👉🏽#Paymentexperts any perspectives to share on #pcidss🎙️? --- 𝑾𝒐𝒏𝒅𝒆𝒓 𝒘𝒉𝒐 𝒘𝒆 𝒂𝒓𝒆?

Welcome to 𝐓𝐡𝐞 𝐏𝐚𝐲𝐦𝐞𝐧𝐭𝐬 𝐀𝐜𝐚𝐝𝐞𝐦𝐲 by Checkout.com — Episode 4 👋 — Topic #4: 𝐖𝐡𝐚𝐭 𝐢𝐬 𝐚 𝐏𝐚𝐲𝐦𝐞𝐧𝐭 𝐕𝐚𝐮𝐥𝐭? ► A Payment Vault (also referred to as a Token Vault) is a secure digital repository that stores sensitive payment credentials, such as Primary Account Numbers (#PANs) and cardholder details. Instead of merchants handling and storing this sensitive information themselves, a vault service provider securely stores it, ensuring compliance with industry regulations such as PCI DSS (Payment Card Industry Data Security Standard). By using a Payment Vault, businesses reduce their exposure to fraud risks and regulatory burdens, allowing them to focus on delivering seamless customer payment experiences. — 𝐇𝐨𝐰 𝐭𝐨 𝐮𝐬𝐞 𝐚 𝐯𝐚𝐮𝐥𝐭 𝐢𝐧 𝐩𝐚𝐲𝐦𝐞𝐧𝐭𝐬 Instead of directly handling and storing customers' Primary Account Numbers (PANs), businesses can integrate with a Payment Vault to securely store and access tokenized payment credentials. How it works 👇 1️⃣ Payment details captured — The customer's PAN is collected via payment gateway integration or a standalone API endpoint. 2️⃣ Tokenization process — The Payment Vault generates a Token (a secure, tokenized version of the PAN) and stores it in the vault, each with a unique ID. 3️⃣ Token replaces PAN in transactions — Instead of using the raw PAN, the assigned token is used to process payments, enhancing security. 4️⃣ Automated updates for expired cards — The Real-Time Account Updater feature ensures stored credentials remain valid, reducing payment failures. 5️⃣ Transaction completes as usual — The remaining payment flow continues through the acquiring bank and card networks. — 𝐇𝐨𝐰 𝐝𝐨 𝐏𝐚𝐲𝐦𝐞𝐧𝐭 𝐕𝐚𝐮𝐥𝐭𝐬 𝐛𝐞𝐧𝐞𝐟𝐢𝐭 𝐦𝐞𝐫𝐜𝐡𝐚𝐧𝐭𝐬? ✅ Regulatory Compliance — Merchants avoid handling raw payment credentials, reducing their PCI DSS compliance burden. ✅ Fraud Prevention — Storing tokenized data instead of actual PANs limits the risk of sensitive data breaches. ✅ Seamless Customer Experience — Vaulted credentials enable one-click checkouts, subscription payments, and faster transactions. ✅ Improved Payment Performance — Features like the Real-Time Account Updater prevent transaction failures due to expired or lost cards. ✅ Multi-PSP Support — Vaulted credentials can be used across multiple Payment Service Providers (PSPs), giving merchants more flexibility in payment processing. — 𝐓𝐡𝐞 𝐌𝐞𝐫𝐜𝐡𝐚𝐧𝐭 𝐏𝐞𝐫𝐬𝐩𝐞𝐜𝐭𝐢𝐯𝐞 𝐛𝐲 Matteo Gamba "For merchants, a Payment Vault isn’t just about security—it’s about unlocking new opportunities in payments.
