To Thwart Stray RFID Reads, IDRO Develops Glowfly
reader, which works in conjunction with an antenna fitted with an LED to activate EPC Gen 2 tags with photoelectric sensors. Radio frequency identification technology is often touted for its ability to read tags without requiring a line-of-sight, thereby making reads much faster than, for example, scanning a bar code. There are also times, however, that non-line-of-sight reading creates problems. The unintended reading of RFID tags can cause data errors in a variety of applications.
