US Patent 11580349 Stackable integrated circuit cards

Systems and methods allow for the integrated circuit cards (ICCs) to removably couple to each other and transmit information to an access device as a single device. One among the two or more ICCs coupled together may read data from the remaining ICCs and provide the data to an access device via contactless communication. The ICC may include a substrate; an integrated circuit embedded in the substrate; input ports exposed on a first surface of the substrate, and output ports exposed on a second surface of the substrate. The input ports and the output ports are electrically coupled to the integrated circuit. The output ports are configured to be removably coupled to the input ports of a second ICC.
