US Patent 11792001 Systems and methods for secure reprovisioning

Systems and methods for authentication may include a first device having an association with a first account, including a memory containing one or more applets, a counter value, and transmission data, a communication interface, and one or more processors in communication with the memory and communication interface. The first device may create a cryptogram based on the counter value, wherein the cryptogram includes the counter value and the transmission data. The first device may transmit, after entry of the communication interface into a communication field, the cryptogram, and update, after transmission of the cryptogram, the counter value. The first device may receive, via the communication interface, one or more encrypted keys and one or more parameters. The first device may decrypt the one or more encrypted keys and, after decryption of the one or more encrypted keys, switch an association from the first account to a second account.
