Abstract
Systems and methods provide for authenticating a user attempting to make a payment using a piezoelectric device are disclosed herein. In an embodiment, the piezoelectric device can be embedded on a credit card, debit card, or other form of payment card and signals generated by the piezoelectric device can be used to authenticate the user when making the payment. For example, the user can squeeze or manipulate the piezoelectric device in a specific predetermined pattern and the resulting electric charge or induced current generated by the piezoelectric device can facilitate transmitting a signal to a point of sale device, and the point of sale device can authenticate the user based on the signal. In other embodiments, the piezoelectric device can contain circuitry and/or logic that can authenticate the user and send a confirmation signal to the point of sale device to authenticate the payment.
