Low Frequency (125kHz)) - The read/write range is very short, no more than a few centimeters, and memory storage capacity is limited. Low data transmission speeds and few tags can be read at once.
High frequency (13.56 MHz) - Short read/write range of several inches, but with large memory capacity and medium data transfer rate.
Ultra-high frequency (860-960 MHz) - remote read-write range up to 70 feet and large data capacity. High Data transfer rates as well.
RFID (radio frequency identification) technology is an automatic identification technology emerged in the 1990s. RFID wristband tag is one of wearable RFID tags in RFID products. RFID users like it because it is easy to wear, easy to carry and fashionable
