Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder...

However, only a few people know how radio frequency identification works. RFID (short for Radio Frequency Identification) describes transmission technology based on electromagnetic waves, which serves contactless data exchange in sender-recipient systems.

What is RFID? We explain what Radio Frequency Identification (RFID) is and give examples of what industries and applications are currently utilizing RFID.

Radio Frequency Identification (RFID) refers to a wireless system comprised of two components: tags and readers. The reader is a device that has one or more antennas that emit radio waves and receive signals back from the RFID tag. Tags, which use radio waves to communicate their identity and other...

RFID (radio frequency identification) refers to the technology in which data is encoded in unique tags and tracked by electromagnetic fields that interrogate radio waves from the labels and feed them into the system. Similar to UPC (universal product code), RFID can be used to track sales at a faster rate...
