Systems and methods relating to tokenization

A computer-implemented method for enabling use of an account in biometric transactions, the method comprising:

• receiving, at a computing device, from a payment network, a request to check whether a payment account of a user is supported for biometric transactions based on presentment of a payment device associated with the payment account, the request including at least one of a cryptogram associated with a transaction to said payment account and a transaction ID for the transaction to said payment account;
• verifying, by the computing device, the payment account is supported for biometric transactions based, at least in part, on the at least one of the cryptogram and the transaction ID being included in a prior transaction;
• transmitting, by the computing device, to the payment network, an indicator of eligibility of the payment account;
• receiving, by the computing device, a request for provisioning of a biometric of the user to the payment account, the request including a payment account number for said payment account;
• verifying the request based, at least in part, on the prior verification of the at least one of the cryptogram and the transaction ID being included in a prior transaction;
• and
• transmitting, by the computing device, a response indicating an approval, or not, for enabling biometric transactions, whereby the payment network notifies the user of the payment account being enabled for biometric transactions.

A non-transitory computer-readable storage medium including executable instructions for enabling use of an account in biometric transactions, which when executed by at least one processor of a payment network, cause the at least one processor to:

• receive a request to provision a biometric for biometric transactions to a payment account, the request including at least one of a cryptogram associated with a transaction to said payment account and a transaction ID for the transaction to said payment account;
• check whether the payment account is supported for biometric transactions with an issuer of the payment account, whereby the issuer verifies the cryptogram and/or the transaction ID;
• receive by the computing device, an indicator of eligibility of the payment account;
• request a biometric from the user, via a biometric reader;
• in response to the request, receive biometric data indicative of a biometric of the user;
• transmit a request to enable biometric transactions for the payment account, the request including a payment account number for said payment account, whereby the issuer verifies the request based on verification of the cryptogram and/or the transaction ID;
• and
• based on a response from the issuer, notify the user that the payment account is enabled for biometric transactions.
