Abstract
A method for generation and distribution of protected user-specific information includes encrypting, by a processing device of a computer system, using a first encryption key of an encryption key pair, predetermined digits of a payment account number, the encryption yielding an encrypted identifier. The processing device of the computer system then generates a machine-readable code that is encoded with the encrypted identifier and additional data. A transmitting device of the computer system transmits, via an electronic communication, the generated machine-readable code to an electronic device of a user and transmits a second encryption key, of the encryption key pair, to a specialized computer system, wherein the second encryption key is associated with the first encryption key used to yield the encrypted identifier.
