1. A transponder, comprising:

  • a capacitor having at least two terminals, where circuit traces are formed on at least one surface of the capacitor and connect to the terminals;

    an integrated circuit mounted to a surface of the capacitor and including a plurality of contacts connected to the circuit traces formed on the capacitor; and

    an antenna coil including two antenna leads that are connected at contact points to the circuit traces formed on the capacitor;

    wherein the circuit traces connect at least two of the terminals of the capacitor to at least two of the contacts of the integrated circuit;

    wherein the circuit traces connect the two antenna leads to at least two of the contacts of the integrated circuit; and

    wherein the integrated circuit includes circuitry capable of generating an identification code signal in response to receipt of an activation signal by via the antenna coil.
