System and method for closing pre-authorization amounts on a virtual token account

Abstract:

A system for closing pre-authorization amounts on a virtual token account is disclosed. The system may receive a transaction authorization request for a virtual token. The virtual token may be associated with a parent transaction account, and have a virtual token ID, a token parameter, a virtual token balance, an authorized variance, and a settlement variance. The transaction authorization request may have a transaction request amount and be linked to the virtual token ID. The system may compare the transaction request amount to the virtual token balance and the authorized variance, and authorize the transaction authorization request in response to the transaction request amount being less than the virtual token balance. The system may compare the settlement variance to the virtual token balance, and expire the virtual token in response to the virtual token balance being less than the settlement variance.
