ISO15693 UHF RFID Reader Writer ISO 18000-6C/ EPC Global Gen2 863MHz~928MHz Module for IC Card Printers
RFID is an automatic identification technology based on devices called RFID tags.RFID uses radio waves produced by a reader to detect the presence of (then read the data stored on) an RFID tag. Tags are embedded in small items like cards, buttons, or tiny capsules. These readers also use radio waves in some systems to write new information to the tags.UHF, the English acronym for Ultra High Frequency, is an automatic wireless communication technology that allows you to read data from a great distance. An UHF RFID reader is a device using an Ultra-High Frequency (UHF) range, between 860 MHz and 960 MHz. Its extended read range compared to HF NFC readers enables one reader to interact with many tags at the same time, at a very high speed, within distances of tens of meters.This RFID reader writer module is the best choice in the development of smart book self service kiosk and librarian workstation devices.
It has fast anti-collision processing algorithm, high label recognition sensitivity and stable performance;
ISO18000-6C/ EPCglobal Gen2
It is widely used in RFID book self-service equipment, handheld devices, desktop tablet all-in-one machines.
The RFID reader is a network-connected device that can be portable or permanently attached. It uses radio waves to transmit signals that activate the tag. Once activated, the tag sends a wave back to the antenna, where it is translated into data.The RFID reader emits radio waves of specific frequencies through RFID antennas. The waves "give energy" to the tags so that they can communicate by emitting a unique ID. They do not need batteries and can be used for many years.
What is the difference between NFC vs RFID?
1. The reader/writer and tag in RFID can be a one-to-many relationship (the low-frequency and high-frequency ISO14443 is one-to-one), while NFC is a one-to-one relationship.
2. In terms of frequency, RFID has multiple working frequencies such as low frequency, high frequency and ultra-high frequency, while NFC only works in 13.56Hz single high frequency spectrum.
3. The communication distance is also very different. NFC is much shorter than RFID. RFID can reach tens of meters, while NFC is only within 10 cm.
4. RFID can only conduct one-way communication (from tag to reader), and NFC can conduct two-way communication. In addition, NFC can only scan one label at a time, while RFID can scan multiple labels at a time. This should be the most significant difference between RFID and NFC.
5. In terms of data reading and writing, RFID can write data into tags with special equipment. In general, NFC data can be read and written from tags or locked as read-only. Extracting data from RFID tags usually requires expensive card readers, while NFC data reading is relatively simple and much cheaper. Now most smart phones are equipped with NFC reading function.
