摘要
This invention provides radio frequency identification devices, wireless communication systems, communication methods, methods of forming a radio frequency identification device, methods of testing wireless communication operations, and methods of determining a communication range. According to a first aspect, a radio frequency identification device includes a substrate; communication circuitry coupled with the. substrate and configured to at least one of receive wireless signals and communicate wireless signals; and indication circuitry coupled with the communication circuitry and configured to indicate operation of as the radio frequency identification device. A communication method according to another aspect includes providing a radio frequency identification device including indication circuitry; receiving a wireless signal within the radio frequency identification device; and indicating operation of the radio frequency identification device using the indication circuitry after the receiving.
