Abstract: 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.

Abstract: A breakaway RFID tag is configured such that it comprises part of a Printed Circuit Board Assembly (PCB). Thus, the breakaway RFID tag can be used to track the PCB as it migrates through a manufacturing process. In one embodiment, the RFID tag can be assembled first and then used to track the PCB as it is populated with components and installed into larger assemblies and ultimately into the end device. Once the PCB is installed into a larger assembly or the end device, the breakaway RFID tag is configured such that it can be broken off and attached to the outside of the larger assembly or end device.

Abstract: A radio frequency identification apparatus for a book management operation is disclosed, which is an RFID library slanted cavity device configured with a non-metallic slanted cavity for users to place and pick items or books conveniently. The RFID library slanted cavity device is configured with RFID readers for accessing information from books or audio/video multimedia items that are operated by users, by that not only the efficiency of the RFID readers to access the RFID tags attached to the books or multimedia items can be enhanced, but also the output power of the RFID readers can be lower for reducing electromagnetic wave leakage to ambient environment, while still working with satisfactory access efficiency. With the aforesaid device, the accuracy of a self-service operation can be enhanced by its ergonomics design, and also a book management operation can be performed efficiently since the RFID tag attached to books can be accessed effectively.

Abstract: A radio frequency identification (RFID) device includes a conductive antenna structure having an elongated slot therein. Parts of the antenna structure on both sides of one end of the elongated slot are coupled to a wireless communication device, such as an RFID chip or interposer. On the opposite end of the elongated slot, parts of the antenna structure at both sides of the elongated slot are electrically coupled together, for instance by being coupled together by other conductive parts of the antenna structure. All of the parts of the antenna structure may be parts of a continuous unitary layer of conductive material. The antenna structure with the elongated slot therein may facilitate increased readability of the RFID device, particularly in directions out from the edges of the RFID device.
