“Financial services giant Mastercard has developed a new type of contactless card that incorporates quantum cryptography, designed to protect against hacks from current classical computers and future quantum computers. The enhanced contactless card uses standards recently revealed by finance industry technical body EMVCo known as “the EMV Contactless Kernel Specifications” that work with all existing payment terminals while also providing higher levels of security that are also “future proof”. When quantum computing technology reaches a point known as quantum supremacy, where the machines can perform near errorless calculations impossible with classical computers, it will also render current cryptography solutions simple to crack, meaning specific quantum security will be required. Experts expect this point to be reached by 2025-2027.    Mastercard says its new card is a “significant milestone that brings quantum-era security and privacy protection to contactless payments”. It will come with next-generation algorithms and cryptographic keys that have been designed to be fast, ensuring a contactless payment happens in under half a second, according to payment vendor, along with enhanced privacy protections to reduce the amount of account information shared between the consumer device and merchant terminal.”
