With the rise of the mobile payment wave, NFC near field communication technology is supported by the central bank and operators. For example, to popularize NFC terminals, China Mobile proposes to subsidize RMB30 for every NFC mobile phone sold. On the other hand, TransferJet near field communication technology with 375Mbps data transfer rate is gradually becoming the new darling of high-speed data transmission technology. In response to these two major market trends, Shiping Group launched NFC and TransferJet near field communication technology solutions.
NFC (Near Field Communication) is a short-range wireless communication technology that uses the 13.56 MHz band. Combined with inductive card reader, inductive card and peer-to-peer function. Although the communication distance is only about 10cm, but as with the non-contact IC card technology, "just touch it", you can exchange data between different electronic products.
Unlike non-contact IC cards, NFC allows bidirectional communication. As long as NFC-enabled products and IC cards, you can read or write data. Also in mobile phones and other portable products for communication. Data transfer speed is not high, with 106Kbit / s, 212Kbit / s, 424Kbit / s and 848Kbit / s four speeds to choose from.

This is an NFC-like near-field wireless technology that allows two digital products to carry high-speed data over a distance of 3cm - 375Mbps, up to 560Mbps maximum, with only 0.1 seconds to establish a connection and low power consumption. If there are two such contacts, then touch can be connected between. Unlike NFC, TransferJet uses a 4.48GHz high frequency carrier from the beginning, designed for high speed, large file and large data volume applications.
