WIRELESS TAMPER DETECTION

Abstract: a payment device and method of detecting a tampering condition of a payment device are provided. the payment device and method include using on-board radios, e.g., ultra-wideband (uwb) radios, to define a reference signature of the payment device and/or the environment surrounding the payment device and comparing the reference signature to a sample signature at periodic intervals or generally over time to determine if a physical change to the payment device has occurred. if the difference between the reference signature and the sample signature is above a predetermined value or threshold, a tamper condition is satisfied and the device may lock down or erase sensitive data, preventing the unauthorized collection of sensitive transaction information.
