RFID FAQ's

What is RFID?

RFID stands for Radio Frequency IDentification, an automatic identification technology that uses radio waves to transfer digital information between a tag and reader.  An RFID tag is comprised of two parts - an antenna for transmitting and receiving signals, and an RFID chip which stores the tag's ID and other information. 

RFID is used in hundreds of...

NFC does not only share the same frequency band (13.56 MHz) but it is based on HF-RFID standards.

Specifically, the NFC interface protocol standard (ISO/IEC 18092 / NFCIP-1) uses components from the RFID standards ISO/IEC 14443 (Type A) and JIS X 6319-4. This essentially merges the technologies MIFARE (by NXP) and FeliCa (by Sony). In addition ISO/IEC 21481 (NFCIP-2) defines...

What is RFID?

RFID tags and Inlays consist of three components: a chip, an antenna and a substrate. RFID tags are manufactured in different shapes and sizes depending on the type of application in which they are used.

RFID operates tags can either be Passive (no internal power source), Semi-Passive (passive but includes a battery) and Active which only operate with a battery.

Active Tags: These tags have a longer read range and larger memories than passive tags and usually operate at 455 MHz, 2.45 GHz, or 5.8 GHz frequencies. Typical read range is from 20 to 100m.
