US 12,461,875 B2 · Smart card with bus interface receptacle printed as part of PCB

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.

Dependent claims

A card device, comprising:

a base layer having a printed circuit board (PCB) and defining a recessed portion, the PCB including:
a tab extending from the PCB and at least partially contained within the recessed portion and shaped to be received within a plug associated with an external device;
and
a bus interface printed on the tab, the bus interface enabling communication between the card device and the external device;
and
a microprocessor mounted on the PCB and electrically coupled to the bus interface.
