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.

The problem to solve is how to extend the operating range of small stackable RFID tags when they are placed in an undesirable orientation. Disclosed is an RFID tag that operates in two modes whereby in a first mode the tag has a short range and in a second mode the tag has a long range. The tag is converted from the first mode short range device into the second mode long range device by placing it close to a coupling device. That is in the second mode the tag becomes a two part RFID tag system (1400) capable of communicating with an interrogator antenna (1407).
