What do I need to pay attention to when using smart IC card coils?
Nowadays, technology is constantly evolving and there are a lot of electronic products around us that you may also use on a regular basis. For example, our ic card coil is one of them. So what do you need to pay attention to when using smart IC card coils?
What do I need to pay attention to when using smart IC card coils?
I believe we all have a lot of doubts in our mind. When we take the bus or subway, we usually use the bus card. So, is there an IC card coil inside? Actually, the bus card contains IC card coil, and the IC card has a chip connected to the coil. When you sense the card, the coil cuts the magnetic lines of force of the magnetic field emitted by the card reader and generates an electric current, and the chip produces a signal that is received by the card reader and sent as specified. This is why we hear a ticking sound when we swipe the card. When you use IC card, avoid putting it together with sharp things and don't be close to magnets, which will cause harm to IC card. Only by taking care of it can you prolong its service life.
What is the difference between smart IC card coil and magnetic stripe card?
1. Among the products, we will recognize a lot of differences, these differences are what we need to know, otherwise our understanding of the product will not be clear, and the coil of the IC card is the same. So what is the difference between ic card coil chip card and magnetic stripe card?
2. Chip card and magnetic stripe card in the appearance of most friends are easy to identify, but its internal functions and application areas many friends are not very clear, and even some friends in the need to make cards will be entangled in the magnetic stripe card or chip card.
3. In fact, the chip card is an upgraded version of the magnetic stripe card. Chip card capacity (storage capacity is 160 times that of magnetic stripe card), can store keys, digital certificates, fingerprints and other information. The card has read/write protection and data encryption protection, with personal passwords and two-way authentication between the card and the reader. It is extremely difficult to copy the card, with high resistance to attack and high security. the stability of IC card is stronger than that of magnetic stripe card, and there will be no demagnetization.
What kind of specification is there for the quality of smart IC card coils?
In the process of buying, we need to know what kind of specification the product has. We can just buy it according to its reference conditions. The same is true for self-adhesive coils. So what kind of specification for the quality of self-adhesive coils?
1.The hardness of self-adhesive coils will affect its impact resistance and inductance. Generally speaking, few manufacturers test the hardness of self-adhesive coils, but in other countries, the hardness is usually tested.
2. The relationship between temperature and inductance As the temperature rises, the inductance will change accordingly, so the inductance shall be compared at the same temperature.
3. Relationship between temperature and inductance change Due to the special properties of self-adhesive coils, the inductance number needs to be controlled by ourselves. If there is any problem such as damage or burning during the manufacturing process, it is necessary to stop the machine for a period of time and start it again after it cools down.
