LF (low frequency) RFID technology does not support reading more than one tag at a time because the reader sends out a low frequency signal that can only interrogate one tag within its range at a time. UHF (ultra-high frequency) RFID technology, on the other hand, can read multiple tags at once due to its ability to emit a high-frequency signal and use anti-collision protocols to differentiate between tags. Smart labels are essentially RFID tags with integrated circuitry and can be compatible with various RFID frequencies. Readers are devices used to communicate with RFID tags and can support single or multiple tag reading depending on the technology used.
