The advantages of non-contact RF card meter are:

1 There are no mechanical contacts and therefore no wear and corrosion problems.

2 circuit sealed, completely solve the moisture, waterproof problem.

3 There is no exposed electrode, so it can effectively resist external strong interference. This is the unique design of the product.

4 No direction when used, can swipe the sensing surface in any direction, avoiding the problem that the contact IC card can only be used in one direction, and also avoiding the difficulty of inserting the card due to the narrowness of the card socket of the contact IC card. Operation is difficult.

5 The advanced nature of data encryption performance and security performance is more prominent, and it is extremely difficult to decipher and copy. This card uses a two-way authentication mechanism. The reader verifies the legitimacy of the IC card and verifies the legality of the reader at the same time. Most of the common contact IC cards are one-way authentication. It is easy to duplicate and even appears as a "black market card." , to the management department has brought huge economic losses.

6 Each card has a unique serial number. The serial number has been fixed before the product leaves the factory. It cannot be changed. The uniqueness of the serial number makes it extremely difficult to crack. Due to the above advantages, non-contact IC cards are widely used in key areas such as residents' second-generation identity and urban public transportation card. Therefore, the application of RF card technology to water meters will be a great revolution for smart water meters.
