Transaction approval based on a scratch pad

Abstract:

A system for conducting transactions without a debit card or credit card may receive a request to complete a transaction including authentication data associated with a transaction account and a captured biometric template. The transaction request may lack information contained on a typical debit card or credit card. The system may identify the transaction account using the authentication data associated with the transaction account. The transaction account may be associated with a stored biometric template stored in a biometric data store. The system may also compare the stored biometric template with the captured biometric template. In response to the stored biometric template conflicting with the captured biometric template, the system may decline the transaction.
