WHAT IS TOKENISED CARD TRANSACTION?

 Tokenisation is a process by which actual card details masks sensitive card details of your debit / credit / prepaid card with an alternate code. This process by which the primary details of a card are replaced with a surrogate value is called a token.

Instead of using actual card details, this token is used to perform card transactions in contactless mode at point of sale (POS) terminals, quick response (QR) code payments. The primary card data, token and other relevant details are stored in a secure mode by the authorised card networks. The Token requestor is not permitted to store Primary Account Number (PAN), i.e., card number, or any other card detail. Card networks are also mandated to get the token requestor certified for safety and security that conform to international best practices / globally accepted standards.
