Detecting component removal
First Claim
1. A system for component movement detection, the system comprising:
- a payment module;
a fuel dispenser, the fuel dispenser adapted to receive the payment module and enclose the payment module at a first position, the first position defined by a fixed position of the payment module relative to the fuel dispenser; and
a movement detection device, the movement detection device communicably coupled to the payment module and adapted to;
detect a first value at the first position and a second value at a second position of the payment module, the second position different from the first position;
transmit the first and second values second to the payment module, the payment module adapted to activate a security measure based upon a difference in the first and second values greater than an adjustable absolute limit;
detect a third value at a third position of the payment module, the third position different from the first position, a difference in the first and third values greater than the adjustable absolute limit;
match the difference of the first and third values to one of a plurality of stored differential values, each of the differential values corresponding to an authorized movement of the payment module relative to the first position including movement resulting from a servicing of the payment module; and
transmit a signal to the payment module to prevent activation of the security measure based on the match.

Abstract
Component removal detection may be accomplished by a variety of systems and techniques. In one embodiment, a system for component movement detection may include a payment module, a fuel dispenser, and a movement detection device. The fuel dispenser may receive the payment module and enclose the payment module at a first position defined by a fixed position of the payment module relative to the fuel dispenser. The movement detection device may be communicably coupled to the payment module and may detect a first value at the first position and a second value at a second position of the payment module, where the second position may be different from the first position. Further, the movement detection device may transmit the second value to the payment module, where the payment module may activate a security measure based upon a difference in the first and second values greater than an adjustable absolute limit.
