Put simply, RFID is similar to barcode technology but uses radio waves to capture data from tags, rather than optically scanning the barcodes. It is an automatic identification technology whereby digital data is encoded in an RFID tag or 'smart label' and is captured by a reader using radio waves.

It is thanks to the ultra-high frequency reading and writing technology that it is possible to register thousands of goods in one second. In addition to encryption, batch reading and writing is also a major feature of UHF tags. UHF tags can be used in areas such as asset management and inventory counts. What about UHF tags reader? Their individual distances can reach 2 to 8 meters or more. They also belong to the category of high frequency tags. And the NFC tag we are familiar with, Near Field Communication, is a kind of near-field read-write protocol tag in popular terms. The reading distance is not good, you don’t want your bank card to be stolen, do you? High-frequency tags reader generally have a reading distance of one or two centimeters. The confidentiality of high-frequency tag is very good, they can use high-level encryption technology, and the read and write distances are often very close. However, general company access control punch cards and other fields do not require high security and encryption. LF tags are cheap and less prone to breakage. The read distance of low frequency tags reader is generally between five millimeters and twenty centimeters. Reading distance, encryption type and other performance are also different. Im working on an Android app with Kotlin, and a Chainway C66 hand-held. Different tag reader correspond to different label types. Then the RFID tag readers naturally divide into low frequency tag reader, high frequency tag reader and ultra-high frequency tag reader. RFID passive tags divide into low frequency tags, high frequency tags and ultra-high frequency tags. RFID tag reader refers to a RFID reader or writer that can read various RFID tags.
