How to Use the NFC mobile payment function

For example, a bus card is used for card swiping, a door card is used for card swiping, a membership card is used for card swiping, and a VIP card is used for card swiping during fitness, the shopping mall uses a bank card or a credit card for credit card consumption, and the medical insurance card is used for credit card purchases ...... So many cards are annoying! It is easy to integrate these cards into one card. The emergence of NFC mobile phones will solve this problem. The question is, how should we use an NFC mobile phone?

 

As we all know, NFC mobile phones have three functions: card mode, read mode, and point-to-point mode. Card Mode means that an NFC mobile phone is simulated into a card. After downloading this card, you can swipe your card to consume the card. The read mode allows an NFC mobile phone to read cards, such as the balance on the bank card and the balance on the bus card. It can also be used as a POS machine. Point-to-Point Mode means that two NFC mobile phones can exchange data. What I want to talk about now is how to use the card mode of the NFC mobile phone to solve the above problem, that is, how to enable our NFC mobile phone to swipe the card.

First, we need to simulate an NFC mobile phone as a card. This is a blank card and there is no application in it, that is, it cannot be used to swipe the card. You need to download the application to swipe your card. For example, you can download the public transport application, click the bus card, download the access control application, and click the bank card to download the application. The key is how to download the application? There are two methods:

One is to take the NFC mobile phone to the bus service point, the waiter will help you download, and then you can use it on the bus. This is to use external reader to download applications to NFC mobile phones. The other is to download an application from an NFC mobile phone. The difference between the two methods is that the former requires an NFC mobile phone antenna, while the latter does not. Their similarities are that the communication protocols used are all APDU commands.

 

apparently, the NFC mobile phone downloads apps for itself to make it easier for consumers and for sellers. For example, a store puts its own app on the Internet. Consumers download the app to their own mobile phone, and the mobile phone can be swiped to the designated store for consumption. For example, if a is on a business trip outside China, the local bus card cannot be used outside China. What should I do? You can download the bus application of that city from the Internet and put it on your mobile phone. Then, this mobile phone will be able to brush bus cards in that city! It is extremely convenient to say!
