Various aspects of the disclosure generally relate to security for a credit card processing reader. Part of security for a reader is protecting sensitive components, for example components that access information from a credit card during a transaction. An alternative security configuration may include integrated circuits replacing portions of electrically active mesh. This may reduce the size and cost of a reader while maintaining its security with respect to published guidelines.

A system for prevention of electrostatic discharge from a payment card to a point of sale (POS) device comprising an integrated circuit card (ICC) socket, includes a spring member comprising a first end electrically coupled to a second end. The first end is electrically coupled to an electrical ground, the first end is mechanically coupled to the POS device, and the second end is positioned for contact with a top edge of the payment card. When the payment card is inserted into the ICC socket and the top edge comes into contact with the second end, the first end and the second end form a first electrical path for electrostatic discharge between the payment card and the electrical ground.

Various aspects of the disclosure generally relate to point-of-sale credit card processing devices. More specifically, the disclosure relates to synchronizing device communications with other device functions in order to reduce cross-platform interference and meet certification requirements.
