Mastercard to Phase Out 16-Digit Card Numbers by 2030

Mastercard has announced plans to phase out the traditional 16-digit card number by 2030, replacing it with tokenisation and biometric authentication. The move represents one of the most significant changes to payment card technology since the introduction of chip and PIN.

Under Mastercard's plan, physical and virtual cards will use dynamic tokens instead of static card numbers, making stolen card data essentially useless to fraudsters. Biometric verification will replace PINs and passwords for transaction authentication.

The initiative is expected to dramatically reduce card fraud, which costs the industry billions of dollars annually. Mastercard's timeline gives merchants, issuers and payment processors several years to upgrade their systems to support the new tokenised infrastructure.
