Methods, computer program products and systems for authenticating an electronic transaction conducted over an electronic communications link with a user device of a transaction authorizer. A method includes establishing the electronic communications link with the user device of the authorizer, receiving an authentication code from an authorizer RFID over the electronic communication link, and determining if the received authentication code matches a stored authentication code assigned to the authorizer. The electronic transaction may proceed if the stored authentication code matches the received authentication code. Also included may be the step of determining if one or more required personal attributes match stored personal attributes associated with the stored authentication code assigned to the authorizer. If so, then the method may include proceeding with the electronic transaction if the one or more required personal attributes match the stored personal attributes associated with the stored authentication code assigned to the authorizer.
