What is RFID?
RFID stands for “Radio Frequency Identification” and is a technical system which can be used to assist the contactless reading and saving of data. The data does not need to be seen or touched as it is solely transmitted via frequency identification.
What are RFID systems?
An RFID system comprises two components: a transponder (with active or passive tags) and an RFID scanner (reader), as well as RFID software in the background.
How do RFID systems work?
The electromagnetic radio waves transmit data effortlessly from the transponder, also referred to as the tag, to RFID-compatible readers such as RFID card readers or smartphones, which then convey the information to the RFID software in the background.
The transponder, which is the actual data carrier of an RFID system, usually comprises an antenna and an electronic microchip. The transponder is entirely passive when out of the reader’s range, as it normally does not include a power supply. The transponder is only activated and can only be identified when in range.
Once the transponder and reader are in their mutual response range, the reader can pick up the signals transmitted by the transponder. Ideally, this happens with fractions of a second.
