Abstract
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.
Claims20
A credit card processing reader comprising:
- a case;
- a printed circuit board (PCB) coupled to the case, the PCB with a first side and a second side, the first and second sides parallel and opposite to one another;
- an integrated circuit coupled to the first side of the PCB, the integrated circuit having a footprint defined by a boundary line drawn around the perimeter of the integrated circuit, the boundary line perpendicular to the plane of the integrated circuit and through the PCB, the integrated circuit having at an input/output (I/O) pin within the integrated circuit footprint and between the top of the integrated circuit and the first side of the PCB;
- a first security mesh coupled to the PCB and including a plurality of electrical traces as part of an electrical circuit, the first security mesh existing on a plane parallel to the first and second sides, the first security mesh outside the footprint of the integrated circuit;
- a via that extends through the PCB from the first side to the second side, the via entirely within the footprint of the integrated circuit;
- and
- an electrode coupled to the second side of the PCB, the electrode configured to access data from a credit card during a credit card transaction, the electrode coupled to the via.
