Consultancy >> RFID

RFID represents a technological advancement in Automatic Identification and Data Capture (AIDC) because it offers advantages that are not available in other AIDC systems such as bar codes. RFID offers these advantages because it relies on radio frequencies to transmit information rather than light, which is required for optical AIDC technologies.
The use of radio frequencies means that RFID communication can occur:
- Without optical line of sight, because radio waves can penetrate many materials,
- At greater speeds, because many tags can be read quickly, whereas optical technology often requires time to manually reposition objects to make their bar codes visible, and
- Over greater distances, because many radio technologies can transmit and receive signals more effectively than optical technology under most operating conditions.
