Non-contact ic card application
Non-contact ic card, parking card, access card, meal card, bus, subway monthly ticket card, supermarket card, medical card manufacturer, Shenzhen Zhengdafei smart card has 18 years of card experience, high-quality production of contactless ic card The printing process in Heidelberg, Germany, customized according to customer needs, can meet the needs of all walks of life.
1. Non-contact ic card working principle
The IC card reader sends a set of electromagnetic waves of fixed frequency to the IC card, and the LC series resonant circuit in the IC card is excited to generate resonance, and the charge is sent to another capacitor for storage, when the accumulated charge of the IC card reader reaches At 2V, the card can be powered, and the data in the card can be transmitted or received from the reader.
2. Introduction of non-contact IC card parameters:
The non-contact IC card information storage capacity is 8Kbit, there are 16 sectors, each sector has two sets of passwords, the working frequency of the IC card is 13.56MHz, the communication speed is 106KBPS, and the card reading can be completed at 1-2MS. According to the retention period of 10 years, the number of rewritable times is unlimited. IC cards have very high intelligence and confidentiality.
3. Non-contact IC card production process:
Card punching → chip placement positioning → antenna winding → bump welding chip and coil → inspection test → printing card fabric → lamination → lamination → inspection test → punch card → inspection → finished product delivery.
4. Non-contact ic card application range
Because the non-contact IC card has more convenient and quick features, it can be widely used in electronic wallets, channel charging control, bus automatic ticketing, automatic parking charging, canteen selling, attendance and access control.
