Bin-conserving tokenization techniques generating tokens in reverse order and employing common device pan with differing pan sequence number values across token instances

Abstract:

A payment token is generated within a token bank identification number (BIN) range, and is linked with an underlying account number of a consumer. A first instance of the token is made available in at least one of a first portable electronic device, a first mobile payment application (MPA), and a first web wallet of the consumer with an associated first primary account sequence number (PSN). A second instance of the token is made available in at least one of a second portable electronic device, a second mobile payment application (MPA), and a second web wallet of the consumer with an associated second primary account sequence number (PSN).
