RFID readers, which depending on the type can also write data, generate an energy field of high-frequency electromagnetic waves via a connected antenna, to which the RFID transponder (RFID tag) is exposed.
RFID readers (read/write devices) for passive UHF RFID - often just referred to as "readers" - generate an energy field of electromagnetic waves via a connected antenna. As soon as a passive UHF transponder enters the energy field, it sends its memory content to the corresponding RFID reader until it leaves the field again. In addition to RFID readers for remote antennas, there are also RFID readers with integrated antennas or mobile variants, so-called handheld readers. You can find out which reader is the right one for your project from our trained, experienced project managers - of course at no cost.
