The Technology
RFID (Radio Frequency Identification) is a variant of AutoID. AutoID refers to automatic identification and data capture, also called automatic identification (Auto-ID). This includes technologies such as barcode, smart label, biometrics, OCR, etc.
RFID technology always requires a transponder (tag), a reader to read the transponder information, and software with interfaces to IT systems and databases.
The main advantage of RFID lies in the completely contactless transmission of a massively increased amount of information. RFID readers require neither physical nor visual contact and can detect a large number of transponders simultaneously (or in a very short time) (bulk detection).
Despite the high amount of information, most transponders (depending on frequency) do not require their own power supply and are often rewritable.
In RFID solutions, we distinguish two fundamental operating principles for data transmission.
Inductive coupling (125 kHz to 13.56 MHz)
– short reading distances
– slow data transfer rates
– problems with iron
Transponders for this range at 125 kHz
Range: up to 30 cm
Good properties in difficult environments
Low data transfer rates
Expensive tags
No anticollision
Transponders for this range at 13.56 MHz (HF)
Range: up to 150 cm
Good properties in difficult environments
Difficulties with metal
Anticollision for 10-40 tags per second
Electromagnetic coupling (400 MHz to 6.8 GHz)
– long reading distances
– high data transfer rates
– liquids affect transmissions
Transponders for this range at 867-869 MHz, 902-928 MHz (UHF)
Range: up to 3 m
Good properties in difficult environments, including with metal
High data transfer rate
Anticollision for 50 tags per second
Many standards
2.45 GHz (passive)
Range: up to 150 cm
Poor properties in difficult environments
Works well with metal
Anticollision for 50 tags per second
In connection with the panel PCs and industrial computer systems manufactured by FORSIS, however, personal data is the primary focus. This means we operate in the range of inductive coupling of transponders.
