The overall history of the payment system development is a constantly improving process for consumer experience. At the very beginning, people bartered one thing for another. Trapped by resource scarcity and the unity of recognition, the liquidity of goods was poor , so trade only took place in some areas. With better liquidity of goods and the development of semiconductor, paper currency transaction has been gradually replaced by bank cards and POS machines later on. Going out without cash has become a trend. Benefiting from the development of communications technology, the real-time online processing ability of POS machine has been constantly boosted. From the originally fixed payment point to mobile payment, from magnetic stripe to IC card and contactless card swiping, from wired to wireless, it has hit the records time and again. SIM800C, the POS machine of the first generation of payment is a small-sized 2G module with the dimension of 17.6*15.7*2.3mm. The operating frequency is GSM/GPRS 850/900/1800/1900MHz, which realizes the transmission of voice, SMS and data information with low-power consumption. With the constant development of the communications technology, the mobile payment has been evolving from 2G, to 3G, 4G and even 5G in the future.

The second impact to cash payment is a result of the strong e-commerce system of China. This impact is stronger and bigger. On February 28, 2017, Jack Ma’s Alipay declared that it would take five years to facilitate China to become the first cashless country. The proportion of electronic payment of China was up to 76.9% in 2017, far exceeding the global average. Two-dimensional code occupies the leading position in the market of mobile payment. Alipay and Wechat Financier are the leaders which account for 54.5% and 39.8% respectively. The bank card literates the bulging purses of people, while two-dimensional code makes bank cards and purses become useless. People’s wish of “to walk across the world with one mobile phone” has really come true. Behind all these, the renovation of communications technology’s contribution cannot be left unrecognized. The scanning payment equipment for the 4G module SIM7600CE with SIMcom are throughout the streets. It is a module with LCC package, supporting the frequency range including LTE-TDD/LTE-FDD/HSPA+/TD-SCDMA/EVDO and GSM/GPRS/EDGE as well as LTE CAT4 (downstream speed: 150Mbps). SIM7600CE has stable performance and compact outlook and is cost-effective. It can realize the transmission of SMS and data information with low-power consumption, which is ideal for the compact design requirements for products.

The third generation of mobile payment revolution is face recognition payment aided by the AI technology. This time it is really free from any external limitations and payment is made as long as the consumer swipes his or her face. Nowadays, the face-scanning payment equipment can be seen everywhere, which means that people do not need any tools such as a subway card, a bus card, or a mobile phone any more. The face recognition only takes less than one second. That is highly accurate and convenient. It frees the hands in the real sense and makes it true that one’s face matters in making a living. SIMcom SIM8905 intelligent module is the supporter behind the scenes in the era of face-scanning.

It is an intelligent module based on the multi-frequency LTE-FDD / TDD / TD-SCDMA / DC-HSPA + / HSPA / UMTS / EVDO / EGDE / GPRS / GSM / GNSS. The maximum upstream rate is 50Mbps and the maximum downstream rate is 150 Mbps. It is designed with a powerful processor and is perfect for intelligent payment, (graphic display) intelligent retail, etc. It has been integrated with the fresh new AI face recognition technology and is easily connected to cash register of the merchants. It is plug and play.

Mr. Yang Tao, the president of SIMcom, remarked, “It is SIMcom’s great honor to be always on the cutting-edge of the times. Our products cover the whole life cycle of mobile payment. We provide customers with comprehensive products and services. From the era of 2G to the present era of 5G+AI, the face-scanning payment equipment of SIMcom intelligent module group has spread all over the streets. SIMcom has invested billions in the technology development and production, which has yielded powerful product competitiveness. In the future, SIMcom will continue to invest capital and labor, as well as accelerate the pace of globalization when the products are constantly improved.

Today, face-scanning payment flourishes everywhere. KFC has realized face-scanning payment in more than ten cities across the country. Ali’s unmanned hotel opened in Hangzhou adopts robots throughout the whole process. Guests can enjoy all the services at the hotel with their faces scanned. Jiangxi People’s Hospital has introduced a total of forty face-scanning payment devices, which make it become the world’s first hospital where patients can book, register and make payment through face recognition. The face recognition technology is also adopted by numerous vending machines at the supermarkets and railway stations. It is really “a face-based era of all the people”.

From the barter system in the ancient times to food coupon, cloth coupon, paper money, coin, and bank card in the modern times, and two-dimensional code, face-scanning payment at present, people have been making payment lighter, faster, and easier. With the constant technical innovation, what will happen in the future? Let’s wait and see.
