Abstract
Example embodiments of systems and methods for preventing chip fraud are provided. A chip fraud prevention system may comprise a device including a chip, wherein the chip is at least partially encompassed in a chip pocket. One or more connections may be communicatively coupled to one or more surfaces of the chip, and a capacitance member may be coupled to a surface of the chip. The capacitance member may comprise a known capacitance value and the chip may comprise a memory containing an applet, wherein the applet is configured to measure the capacitance value of the capacitance member.

A method of preventing chip fraud, the method comprising the steps of:
- measuring, by an applet in the memory of a chip installed in smart card, an initial capacitance value from the smart card;
- measuring, by the applet in the memory of the chip installed in the smart card, a subsequent capacitance value from the smart card;
- and
- comparing the initial capacitance value against the subsequent capacitance value.
A chip fraud prevention system comprising:
- a chip installed in a smart card, the chip comprising a memory containing an applet configured to:
- measure an initial capacitance value from the smart card;
- measure a subsequent capacitance value from the smart card;
- and
- compare the initial capacitance value against the subsequent capacitance value.
A smart card comprising:
- a chip embedded in the smart card, the chip comprising a memory containing an applet configured to:
- measure an initial capacitance value from the smart card;
- measure a subsequent capacitance value from the smart card;
- and
- compare the initial capacitance value against the subsequent capacitance value.
