Disclosed herein are methods and systems of preventing fraud during a financial transaction. A consumer can subscribe, enter, and store their personal and business credit and debit card information, account numbers, pin numbers, logins, and passwords on a secure website. The consumer also can upload biometric data, such as a thumbprint or fingerprint, to the security system using a smart phone or tablet. The thumbprint and fingerprints act as the consumer's identifier when using the service and system. At the point of sale, the consumer places their thumb or finger on the biometric reader. The purchase amount is sent to the security system after the consumer chooses a credit or debit card. The security system sends a request for payment to the credit card company if the thumbprint matches. The credit card company determines whether to approve the transaction and if so, remits payment to the security system. The security system then remits the payment to the vendor. |
