RCC and NFC digital currency

1.

It must be domestic

for domestic distribution. If it's international

it's hard for many people to understand

2. NFC means near-field communication, that is to say, close use, such as bus and subway card
digital currency transactions only use the network, which has nothing to do with NFC. Of course, it can be used.

3. When the central bank's digital currency is used, the mobile phone must have NFC function to pay.

4. NFC should be a way of digital currency transaction, as far as internal test is concerned. The official explanation is that the digital currency wallet has the functions of scan code payment, payment code, touch and remittance. NFC is the hardware condition of near-field NFC payment, and NFC should not be the necessary condition of digital RMB.

5. So far, the central bank has not issued digital currency. At present, the digital currency in the market is deceptive. Be careful to be cheated.

6. Mobile payment instry has just started, which technology has been controversial. Japan dominated near field communication technology (NFC) has been widely used in Japan and has become an international standard. However, its limitations also lead to the failure of NFC outside Japan. With the popularity of smart phones, the development of NFC in Japan is also slowing down. In recent years, China's domestic instry has successfully developed the limited area communication (RCC) mobile payment technology, which overcomes the limitations of NFC and successfully realizes large-scale application.

7. Controlled by foreign interest groups
eager for quick success and instant benefit, not respecting or developing China's core technology.

8. Huawei did launch NFC payment with UnionPay through cooperation with Yingtao app< Br > < br > with one touch, UnionPay has a new payment method, which is based on the NFC mole of smart phone and the label payment technology of UnionPay. It can unlock the mobile phone and pay at one touch. UnionPay touch has supported nearly 100 models of Huawei, Xiaomi, Samsung, oppo, vivo, Meizu, apple and other seven brands< Br > < br > in terms of security, the cloud flash payment app is more secure. Cloud flash payment is an app, a non cash collection and payment mobile transaction settlement tool. Under the guidance of the people's Bank of China, it is a mobile payment app jointly developed, constructed, maintained and operated by China UnionPay, commercial banks, Payment institutions and other instrial parties. It was officially released on December 11, 2017< Br > < br > for details, please check the official website or contact UnionPay customer service< br>

9. 1. General single-chip security smart lock scheme: General single-chip security smart lock scheme mainly includes: Security Master MCU, voice mole (DAC), communication mole (WiFi / Bluetooth, Nb IOT mole, RCC / NFC swipe card mole), display mole (OLED, LED light), storage mole (flash), data mole (TSC touch, fingerprint mole), unlocking mole (unlocking motor, oblique tongue control) Battery and other eight moles. The traditional power supply and communication mole has the advantage of strong function, but the proction cost and maintenance cost are also very high. On the other hand, it is not the most economical solution

2. NFC passive intelligent lock technology solution aka: NFC wireless power supply intelligent lock technology, relying on self-developed special NFC core chip, the patented chip technology first breaks through the technical bottleneck of low power supply efficiency of traditional NFC, one "core" multi-purpose, can complete data communication processing, algorithm operation and power output control at the same time, The terminal circuit using the chip can obtain more than 200MW Power through NFC signal of mobile phone and handheld terminal, which is more than 4 times higher than traditional technology. The output power is enough to drive the motor of intelligent lock to drive the special locking mechanism. The lock body does not need to be equipped with power supply and traditional communication mole, only needs the NFC power supply of the mobile phone to open and close the operation, which is convenient to operate, and does not need to worry about the lack of battery power, battery aging, network disconnection and other problems. It is truly maintenance free, and the use experience is more convenient. In short: NFC smart lock solution is to attribute most of the functions of the traditional smart lock to the user's mobile phone, so there is no need for too many moles in the smart lock body, the real single chip completes all!
