Abstract
A method of accessing an account includes receiving, from a device, randomly generated seed information and an encrypted key or token generated by a card using the randomly generated seed information via a contactless communication between the card and the device; decrypting the encrypted key or token using a decryption process that includes the randomly generated seed information and the encrypted key or token as inputs in response to determining that the randomly generated seed information does not match previously received seed information; and providing, to the device and based on the decrypted key or token, access to the account.
