Radio frequency identification (RFID) is a kind of automatic identification technology. It carries out non-contact two-way data communication through radio frequency, and uses radio frequency to read and write recording media (electronic tag or radio frequency card), so as to achieve the purpose of identification target and data exchange, It is considered to be one of the most potential information technologies in the 21st century
The handheld rfid reader is a device that uses radio frequency identification technology to achieve electronic tag information collection, transmission and communication functions. It has the characteristics of fast group reading, long-distance reading, and long service life, so handheld rfid read and write What is the reading distance of the device?
NFC is a short-range, high-frequency radio technology. The NFCIP-1 standard stipulates that the communication distance of NFC is less than 10 cm, the operating frequency is 13.56MHz, and the transmission speed can be 106Kbit/s, 212Kbit/s or 424Kbit/s. NFCIP-1 specifies in detail the transmission speed, encoding and decoding methods, modulation scheme, and frame format of the RF interface of NFC devices. This standard also defines the transmission protocol of NFC, including the start-up protocol and data exchange method.
The FDA is fast-tracking the COVID-19 vaccine, and it is ready in some areas. However, a key distribution factor posed a major challenge: keep it cold and refrigerate.
Near Field Communication (NFC) is an emerging technology. Devices using NFC technology (such as mobile phones) can exchange data when they are close to each other. It is evolved from the integration of non-contact radio frequency identification (RFID) and interconnection technology.
NFC is a wireless connection technology that provides easy, secure and rapid communication. Its transmission range is smaller than RFID.
