In the past, IC card-type electric energy meter and one card (water and electric heating) systems were used with contact IC cards, which had weak anti-interference capability and outstanding quality problems, especially open read/write windows. It is vulnerable to external attacks. The hitag RF card and its supporting read/write modules completely solve the above problems. The cost is only slightly increased, but the product quality is greatly improved.
Hitag is used. It is the same as the Atmel water meter, which is common in many cities. It uses a KHz frequency, and the card reading chip price is cheaper than the current Atmel, and the card price is also much cheaper. It uses the card chip is HITAG-S, storage space is 32bit, 256bit. 2048bit, can meet your big data storage needs. The confidentiality and stability are much better than those of the Atmel solution.
The above solutions have successful cases, and we will provide a full set Technical materialsAnd Source ProgramAnd circuit diagram. Please contact us for details. Thank you!
