RFID-based Identification: a Measurement Study.

In this paper we investigate the feasibility of using UHF RFID as a tool for identifying individuals. We first developed a demo application for greeting conference speakers by incorporating a passive UHF tag into a user badge. Next, based on participant feedback we carried out additional tests to gauge the reliability of the user identification. Results of our experiments are very encouraging. If certain technical precautions are kept in mind, UHF RFID has a high percentage of success and is more widely accepted in the user community than is active sensor technology.
