    Abstract: An approach is provided for authenticating a payment card. Information is read from the payment card being used for a purchase. The information includes an identifier and data on a chip, in braille cells, and in markings in the payment card. A hash read from the chip, the identifier, and security codes derived from the braille cells and the markings are sent to a payment system. A hash of an (n+1)-th block of a blockchain is received and recorded in the chip in response to validations of the hash as matching a hash of an n-th block of the blockchain, the identifier, and the first and second security codes, and a generation of the hash of the (n+1)-th block. Data about the purchase and the hash of the (n+1)-th block are sent to the payment system.
