What does RFID mean?
RFID stands for Radio Frequency Identification It involves a process which uses radio waves to read or write data of an electromagnetically coupled data carrier (transponder).
How does an RFID work?
Put in simple terms a reader for the UHF frequency band uses an antenna to send a signal and power to its environment. An exchange of data can take place if a transponder can be activated by the power. The transponder also sends signals in response to the commands of the reader. The advantage of RFID is that it does not need a line-of-sight connection between reader and transponder, such as optical processes using barcodes or QR codes. Moreover, the data contents of the transponder can be read as well as changed as required.
Where is RFID used?
The application areas differ greatly; they are used wherever it makes sense or is of interest to identify objects or living beings. RFID is the first choice particularly when a line-of-sight connection is not possible between the objects or the data needs to be changed.
For example: access control, tool ID, pallet tracking, theft protection, tier identification, product identification
What is an RFID reader?
An RFID reader is a piece of hardware for recording and generally also for writing to transponders.
What is a RFID-transponder?
A transponder is a small data carrier. It is normally attached to the object to be identified and contains a small circuit with a memory area and an antenna for reading and writing. Passive transponders do not require a battery. They function using energy harvesting, i.e. they draw the required energy solely from the energy provided by radio waves. This enables them to be used self-sufficiently and maintenance-free over long periods of time.
Does RFID also function on metal?
Special conditions require special solutions. Special transponders (on-metal transponders) are tuned to compensate for the effects of metal or they provide a physical distance to the metal.
What is the difference between RFID and UHF RFID?
There is no difference, UHF is merely a frequency band for RFID. In addition, there are other popular RFID frequency bands, such as LF (low frequency) or HF (high frequency). UHF stands for Ultra High Frequency and works in the frequency range from approx. 850 to 950 MHz and above.
What are the advantages over other ID methods, in particular barcodes?
RFID does not necessarily need a line of sight with the object to be identified. The transponder can be read and written to as long as it is in range. On the other hand, a barcode must always be "seen" by the barcode reader.
Normally, a RFID TAG can be overwritten repeatedly, however, with a printed barcode changes are unfortunately not possible. Another big advantage of RFID (particularly UHF) is bulk reading, which enables quick detect of multiple transponders (up to a few hundred depending on the reader). For example, you can use a device to detect the objects on a pallet while driving by it in a forklift truck. With barcode systems, this could only be done for a relatively small number of objects using sophisticated vision systems and only with line-of-sight.
