Global: Mastercard Introduces ALT ID Solution for Secure Guest Checkout Transactions

Mastercard has unveiled a new security solution known as ALT ID for guest checkout transactions, bolstering online payment security for both consumers and merchants.

ALT ID is a tailored capability developed by Mastercard, designed to generate an alternative identifier for the genuine card numbers provided by cardholders during guest checkout transactions on e-commerce platforms.

Previously, Mastercard introduced a card-on-file tokenization solution that allowed cardholders to complete transactions securely without exposing sensitive card details. The ALT ID solution is specifically designed for cardholders who opt for guest checkout, meaning they do not save their card details. It generates and securely stores an alternate identifier for each card, significantly enhancing the security of online payments.

Anubhav Gupta, Senior Vice President, South Asia, Mastercard, commented, “The ALT ID solution is yet another testament to Mastercard’s constant endeavor to introduce innovative products and solutions that are compliant, user friendly, and enhance the safety and security of digital payments while making them seamless for both merchants and cardholders. By ensuring a safer shopping experience, this solution will also support the growth of e-commerce in India.”

Sheetal Lalwani, Co-founder & COO, Juspay, added, “The launch of ALT ID will support our efforts to secure the digital experiences of cardholders who don’t wish to save their cards with merchants. Leveraging the Juspay platform, we are ensuring that our merchants are able to seamlessly transition customers to ALT ID without any changes at their end.”

The ALT ID solution offers numerous benefits to cardholders, including the non-storage of card numbers on merchant websites and protection against potential data breaches. For merchants and payment service providers, it enables them to enhance card number security with minimal development efforts and improve the overall payment experience for their customers.

Mohit Gopal, COO, PayU India, noted, “Mastercard’s ALT ID Solution for guest checkout transactions underscores PayU’s foundational commitment to elevating digital payment security, convenience, and accessibility. This innovation will empower cardholders, merchants, and payment service providers like us with a streamlined and fortified approach to online transactions.”

Khilan Haria, SVP and Head of Payments Product, Razorpay, expressed, “We are delighted to collaborate with Mastercard for its innovative ALT ID solution for guest checkout transactions. This association will benefit merchants through higher payment success rates and no integration effort. It will also strengthen our commitment to developing a more secure and comprehensive ecosystem for digital payments.”
