RFID Reader, RFID antenna
An RFID reader is a device that is used to interrogate an RFID tag or RFID cards etc. The reader has an antenna that emits radio waves; the tag responds by sending back its data.
A number of factors can affect the distance at which a tag can be read (the read range). The frequency used for identification, the antenna gain, the orientation and polarization of the reader antenna and the transponder antenna, as well as the placement of the tag on the object to be identified will all have an impact on the RFID system's read range.
OPRFID Technologies supply UHF ISO18000-6C rfid reader, HF ISO14443A/B rfid reader, HF ISO15693 rfid reader, NFC etc reader/writer.
