Abstract: An identification verification device includes an input operable to receive an identification verification query relayed by an account hosting entity. The identification verification query includes a temporary code received from a user. A comparator is coupled to the input and is operable to compare the received temporary code with a verification code. An output transmits to the account hosting entity one of an authorized and a not authorized response that is based upon the comparison.

Abstract: A secure economic transaction device includes a memory for storing user account information, a temporary code generator coupled to the memory and operable to generate a code based upon the user account information that is valid for only a finite amount of time, and a wireless transmitter operable to wirelessly transmit the user account information and the code.

Abstract: A secure economic transaction device includes a memory for storing user account information, a temporary code generator coupled to the memory and operable to generate a time-based code that is valid for only a finite amount of time, a programmable magnetic stripe on a surface of the device and operable to magnetically transmit at least a portion of the user account information and the temporary code to a stripe reader, and stripe programming circuitry located on the device, coupled to the temporary code generator, and operable to dynamically program the magnetic stripe with the code. Also provided is a method for conducting the transaction.
