Abstract
This disclosure a smart card device that provides a bus interface, such as a USB-C bus interface, printed on a portion of a PCB that forms a base layer of the smart card device. The smart card device can provide the bus interface without having to mount a traditional socket. By leveraging the portion of the PCB to provide a printed bus interface and excluding the traditional socket, the bus interface can be easily manufactured using well-known PCB manufacturing techniques while significantly reducing manufacturing costs. Furthermore, the smart card device can have a thickness that conforms to known card form factor standards, enabling the smart device to fit within a standard wallet. To enhance durability of the portion of the PCB from wear-and-tear, a metal core can be added to the PCB as an additional layer. The portion may also be reinforced with edge plating.
