Abstract:
Example embodiments of systems and methods for data transmission between contactless card and receiving devices are provided. In an embodiment, the contactless card may be configured to create a cryptogram based on a plurality of keys and a counter. The cryptogram may be transmitted to the receiving device. The contactless card may be configured to transmit a one-time password to the client device. The counter value may be adjusted each time the one-time password is generated, and the counter may be configured to increment in a non-monotonic sequence, the sequence associated with one or more cryptographic algorithms.
