How NFC shook up the payment market: principles, expected effects, and threatened financial industry

NFC is a short-range wireless communication technology that allows payments or information exchange to occur simply by holding the mobile phone close to the terminal. After organizing the principles and components of NFC, the data predicts what changes will occur in the mobile financial market and which industries will be threatened.

What kind of technology is NFC?

The data defines NFC as a short-range wireless technology that communicates at a distance of about 10cm in the 13.56MHz band. It is derived from RFID and has similar operation methods and characteristics, and was first announced as an international standard in 2004.

The fact that the communication distance is short is actually an advantage. Since it only works when held intentionally close to it, it can reduce the risk of unintentional payments or information leaks.

What mode is NFC used in?

NFC provides a variety of life convenience services through card emulation that uses a cell phone like a card, P2P where two devices exchange information directly, and reader/writer mode that reads or writes tags.

For this, SE, NFC antenna, and NFC controller chip that safely store personal information are required. Security can be increased because payment information is stored separately in the SE.

The communication method is divided into a passive mode in which only one side uses power, and an active mode in which both sides send signals. Passive mode is used when reading tags without batteries, such as transportation cards, and active mode is used when sharing information between mobile phones.

What services have been attempted?

The data introduces examples of services promoted at home and abroad. There are mobile wallets of global companies, NFC experience zones in downtown commercial districts, mobile payment services in overseas cities, and international expo experience zones.

Payment devices that accept multiple payment methods on one terminal have also appeared. From a store's perspective, it is important to be able to accept both existing cards and mobile payments to avoid losing customers.

What are the positive and negative effects?

The positive effect of the data is that a new payment service will be created and it will become a marketing platform that combines payment, coupons, and advertising. Let's look.

On the other hand, the problem of slow distribution of infrastructure such as payment terminals and security threats are cited as negative effects. As convenience increases, protection against hacking or loss becomes more important.

Which industries are threatened?

Data predicts that fintech services such as mobile pay will pose a threat to financial operators such as existing credit card companies and banks. A case is introduced in which large overseas banks saw this as a serious threat and increased their digital payment staff.

In the assignment, it would be good to organize it in the order of technology principles, market changes, effects, and threatened industries, and at the end, add your opinion on how existing financial companies can respond. For payment market share and service status, please check and cite the latest statistics from the Financial Supervisory Service and the Bank of Korea.
