If we carry a phone with a RFID-SIM card, we can go to Starbucks or McDonalds to "brush" our breakfast, then brush our phones to take the subway, after we arrive at the Expo Park, brush our mobile phone to verify electronic tickets, and when we visit the venue, we are thirsty. You can also brush your phone on an automatic shopping machine to buy drinks and water. This is the mobile phone payment. The mobile phone card already has a bus card, a supermarket card and even a bank card. And this is just one of the basic applications of RFID that will support the rise of the entire Internet of things industry.
The RFID SIM card, launched by China Mobile, is similar to a public transport card in places such as Beijing, which records the balance of mobile phone wallets through an internally integrated RFID chip and exchanges data on card consumption. Merchants pay for POS devices as readers, while consumer phones' RFID chips are tags. In fact, the bus card also has a RFID chip built in. The difference is that the mobile wallet can be recharged and settled remotely through the cooperation between the mobile operator and the bank. In this way, all the processes from recharge to consumption can be done through a mobile phone.
In fact, with RFID, mobile operators act as a consumer payment platform, somewhat similar to third-party payment platforms such as Alipay, which uses Taobao on computers, and Tencent's Tenpay, among others. But the popularity and ease of use of mobile phones far more than computers, coupled with a large number of users, as soon as mobile payments like Japan and South Korea-like the mature, operators can imagine the huge benefit of the deposit of funds and fees revenue. Operators through the carrier of mobile phones will directly connect users to the e-commerce market to complete the various functions of e-commerce.
