Today, a customer asked me, "does the IC card ID card have a coil?" What's the use? "I believe there are many customers who have the same question. Let me solve this doubt for you.

In fact, both IC card and ID card have coils, but it is difficult for us to tell from the appearance of IC card ID card. If we want to tell whether it is an IC card or an ID card, we need to observe carefully. Very often, we can still see the coil distribution of the card from the surface of the card, because when the craftsmanship of some cards is not so good, the position of the coil and the surface of the card are very uneven (even if the packaging process is very good. You can also see a little trace), the coil of the IC card is distributed along the four sides of the card, about 3-5mm from the edge of the card, which is generally rectangular. The coil distribution of the ID card is a positive circle, usually in the middle of the card, either left or right, so we can confirm the IC card and ID card from the shape of the coil. If you can not use the above method to judge, it is better to send it to a professional business card printing manufacturer ...
... for testing.

What is the use of the coil of IC card ID card? In fact, the coil of the IC card ID card is the same as the antenna that receives the TV signal, except that the coil of the IC card ID card is used to receive the signal sent by the IC card ID card reader, at the same time, it can also send the signal to the IC card ID card reader, so as to realize the exchange and communication of information and data. Often the size of the coil area affects the induction distance of the IC card ID card.
