Abstract
A point of sale (POS) device includes tamper detection circuitry in which one or more flexible members that each include multiple side-by-side conductive traces connect two circuit boards, optionally so that one circuit board must remain very close to the other if the device remains in a secure un-tampered-with state. Severance of a trace of the flexible member, or disconnection of the flexible member from either circuit board, may result in unexpected voltage sensor readings indicative of a tamper attempt.
