rfid reader vs antenna RFID is an acronym for Radio Frequency Identification which means RFID is the wireless, non-contact use of radio frequency waves to transfer data and identify objects, animals, or humans. RFID systems are usually comprised of an RFID reader, RFID tags, and antennas. The PN532 NFC module, as its name implies, is based on PN532 chip and used for 13.56MHz near-field communication. The module is equipped with onboard antenna, thus no external antenna coil is needed. It is compatible with SPI, .13.56mHz PN532 NFC card-reader module: 13.56MHz, NXP PN532 chip, SPI/IIC/UART interface, ISO14443 Type A/B, 3.3-5.5V, max current 150mA. .

RFID is an acronym for Radio Frequency Identification which means RFID is the wireless, non-contact use of radio frequency waves to transfer data and identify objects, animals, or humans. RFID systems are usually comprised of an RFID reader, RFID tags, and antennas.An RFID reader antenna is a fundamental part of the RFID system, serving as a bridge between the RFID reader and the RFID tags. Its primary function is to transmit radio frequency signals to the tags, prompting them to respond with their stored information.

An RFID reader typically consists of three main components: a transceiver, an antenna, and a controller. The transceiver emits radio waves, while the antenna receives the reflected signals from the RFID tags .RFID Antennas: Function: RFID antennas are responsible for emitting and receiving signals to communicate with RFID tags. They play a crucial role in enabling the wireless exchange of information between the tag and the reader. RFID Readers: Function: RFID readers control the entire RFID system.The tag’s antenna is conductive material that, when struck with electromagnetic waves, induces an electric current powering the IC on the tag. The tag then “turns on” and starts broadcasting its data. It's then the reader's job to interpret the signal received from the tag into usable data.
A key aspect of any RFID antenna is whether it is a far-field or near-field antenna. The difference in the two is the way in which they communicate with an RFID tag. Near-field RFID antennas typically use magnetic or inductive coupling to communicate with the tag when it .

An RFID reader is a network connected device (fixed or mobile) with an antenna that sends power as well as data and commands to the tags. The RFID reader acts as an access point for RFID tagged items so that the tags’ data can be made available to business applications. Systems include the tag itself, an associated antenna, and a reader (with its own antenna) that creates the field and communicates with the tag. Some vendors sell tags as complete units with the antenna.RFID antennas are responsible for transmitting and receiving radio frequency signals within the system, and their performance directly determines the distance and accuracy of tag identification. Typically, RFID readers are monostatic. Monostatic systems use the same antenna for both receiving and transmitting purposes. As shown in the figure below (Figure 1), both antennas in the system first transmit and then switch modes and start receiving RF energy.
