To Thwart Stray RFID Reads, IDRO Develops Glowfly

The Korean company plans to soon release its 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.
