The RFID read/write unit generates the transmit signal, filters the response signal and prepares the information for transfer to an RFID evaluation unit. Information is sent to the transponder via an integrated or external antenna. The magnetic or electromagnetic field emitted via the antenna of the RFID read/write unit also supplies the chip in the transponder with energy (passive and semi-active transponders). The transponder (TAG) is thus able to receive and transmit data. The data returned by the transponder is captured again by the RFID read/write head.
Passive TAGs are suitable for near field communication. The RFID chip stores data on EEPROMS, non-volatile memory chips. The data is thus stored on the RFID chip for a long time without voltage being applied. The data can be electrically erased.
Semi-active RFID tags are equipped with an internal backup battery. This supplies the microchip on the transponder. However, as with the passive transponder, the energy emitted by the reader is used to send the data.
Active RFID tags have their own power supply and can also transmit the stored data over greater distances. SRAM memories can also be used on active TAGs, since these TAGs have their own power supply, which is required to maintain the stored data. Active TAGs offer a faster response time compared to passive TAGs, in addition to the greater range. Due to its own power supply, sensor elements, for example, can also be installed in the TAG. The service life of the transponder battery must be taken into account.
RFID frequencies
The most common are the license-free ISM bands. ISM stands for Industrial-Scientific-Medical. The following areas are typically used for RFID systems:
• Low Frequency (LF): (100…135 kHz)
Indicators: Typical reading ranges approx. 20 cm. The coupling between the reader and the transponder is inductive. The reading speed is relatively slow. Tags operating in this frequency range are relatively inexpensive and small in size. An example of use is animal identification.
• High Frequency (HF): (6,78 MHz, 13,56 MHz, 27,125 MHz)
Indicators: Typical reading ranges approx. 2 m. The coupling between the reader and the transponder is inductive. The reading speed is higher than with LF. Application examples are the payment systems, smart label.
• Ultra High Frequency (UHF): (433.92 MHz, 868 MHz and 915 MHz)
Indicators: Typical reading ranges approx. 12 m. The coupling between the reader and the transponder is electromagnetic. The reading speed is relatively high. UHF application example is the warehouse and logistics area. UHF systems are also suitable for capturing a large number of identifier data (Multitag ®). In this frequency range, liquids can impair transmission.
• Microwave: (2.45 GHz, 5.8 GHz)
Indicators: Typical reading ranges more than 10 m. The coupling between the reader and the transponder is electromagnetic. The reading speed is very high. An example of use is vehicle identification (toll systems).

What is an RFID read/write unit or RFID head?
An RFID read/write unit or RFID head is an electronic device that is used to read and write data from RFID tags. RFID stands for Radio-Frequency Identification and is a technology in which information is exchanged wirelessly via radio waves between an RFID tag and a reader.
The RFID head consists of an antenna, a transceiver (transmitter and receiver), a control unit and an interface for communication with a computer or other device. The antenna emits radio waves to activate the RFID tags in the vicinity and retrieve the information stored in them. The transceiver enables communication between the RFID head and the RFID tags. The control unit controls the process of reading and writing data. The interface enables the RFID head to be connected to an external device for further processing of the captured data.
RFID read/write units or RFID heads are used in various applications such as logistics, retail, access control, warehouse management and many other areas where wireless identification and tracking of objects is required.
