The invention provides a card reader, which includes two USB connectors of two specifications hidden in the body. The two USB connectors are rotatably combined in the body, and a user can choose to use one of the USB connectors to rotate out one side of the body and position it to electrically connect to a main circuit board. A card slot is provided on the opposite side of the body. When one of the USB connectors is rotated out of the body and connected to an electronic device, a chip card inserted into the card slot can communicate with the electronic device. When not in use, the two USB connectors can be rotated into the body and the electrical connection is disconnected for easy storage and portability.

Various aspects of the disclosure generally relate to security for a credit card processing reader. Part of security for a reader is a secure cover having a trace mesh to discourage drilling through the cover. The mesh may be connected to one or more landing areas on the cover. The landing area has electrical pads with trace routing that provides tamper protection for the landing area.

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.
