Abstract
A method and apparatus for wirelessly performing identification. A wireless communications apparatus comprising a cellular receiver communicatively coupled to the processing unit and a first antenna and configured to perform wireless communications via the antenna using a first protocol. The wireless apparatus further contains a short range wireless communications module coupled to a second antenna and configured to perform wireless communications via the second antenna by modulating a radio frequency field using a second protocol, the second protocol being different than the first protocol. In accordance with the second protocol the short-range wireless communications apparatus uses a random number as an identifier of the short-range wireless communications apparatus. The wireless device employs a location determining unit and a communication port configured to provide a control signal to a second device via a wired connection.
