Tokenisation and Encryption in Digital Payments: Fintech

Understand tokenization in digital payments: replace sensitive card data with nonreversible tokens, with device-specific tokens, a token vault, and PCI DSS standards, enabling secure in-store, in-app, and online payments.

Learn how tokenisation in digital payments replaces card details with tokens via token requester and token service provider, validated by issuer bank and OTP, stored in secure device elements.

Discover how to add a card for tokenization through manual entry, photo capture, or in-app provisioning. See how device-specific tokens and virtual cards in digital wallets enable secure, transaction-ready payments.

Explain how card registration and token generation work in tokenization, from mobile wallet encryption to token service provider OTP checks and storing tokens in a secure element for future payments.

Explore how a tokenized transaction flows from the device through the acquirer and payment networks to the issuer, with the token vault and token service providers keeping card data secure.

Understand network-based tokenization, where card networks like Visa, MasterCard, and Amex issue and manage tokens, store token data, coordinate with issuers, token service providers, and wallets for secure payments.

Explore how Visa tokenization converts a card number into a secure token through the token requester, issuer OTP validation, and delivery to wallets such as Apple Pay and Google Pay.

Explain how Apple Pay tokenisation creates a device account number token via the card network and token service provider, stores it in the secure element, and protects card data.

Explore the definitions and differences between encryption and tokenization, and how tokenization enhances digital payments security via token vaults and non-reversible tokens.

Explore how encryption and tokenization secure digital payments, from capture-time encryption to token generation, token vaults and hardware security modules, with examples like Apple Pay and Google Pay.

Explain how hardware security modules secure keys and enable real-time encryption, decryption, tokenization, and PIN verification in digital payments, whether on-premises or as a cloud service.

Explore how PCI DSS governs tokenization in digital payments, detailing single-use and multi-use tokens, how tokens map to card numbers across devices, and merchant implications.

Explore the components of tokenization under PCI DSS, including token generation, token mapping, token vaults, and cryptographic key management, and understand how these elements secure card data.

Identify and compare tokenization deployment models: on-premise, outsourced cloud, and hybrid, highlighting merchant responsibilities, third-party roles, and certification through PCI DSS and EMV core requirements.

Explain merchant responsibilities under PCI DSS tokenisation, enforcing clear contracts, due diligence, and segmentation controls with service providers to protect cardholder data.

Understand open authorization and tokens in digital payments, including access and refresh tokens, which enable limited third-party access without sharing passwords. Learn why this is authorization, not authentication.

Tokenization enables merchants to securely store cards on file for future transactions, one-click checkout, and mobile wallets, while reducing the PCI DSS scope.
