Abstract: A system that supports multi-stage transactions through the use of biometric tokens, such as fingerprint images or iris scans. A user pre-stages a transaction by providing transaction details that can be used a later time to complete the transaction, and the system stores the transaction details in a transaction record that is identified by a biometric token captured from the user. In some systems, the biometric token is captured as part of the pre-staging process. In other systems, the biometric token is retrieved from a data store after the user has provided authentication information, such as a bank card or user-identification code coupled with a secret PIN code. When the user is ready to complete the pre-staged transaction, the system captures a second biometric token from the user and matches the second token to the one identifying the user's transaction record. The transaction details contained in that transaction record are then used to complete the user's transaction.
