Smart card ID card production

Smart card manufacturingThere are many types inside, which can be roughly divided into ID cards and IC cards. Today, we're going to explain how to make an ID card. The storage space inside an ID card is relatively small and mainly records a number, while the machine only recognizes the number inside the ID chip. If the machine recognizes the ID card number correctly, it can perform the required functions; if the machine recognizes the number inside the ID card incorrectly, the function cannot be realized.

For example, I have a door with a lock hanging on it, and there's a machine next to it. My machine needs a designated ID card to open the door. First, we need to bring the ID card to the machine, then gently swipe it, and the door will open. The principle is that the machine can only open the door after it recognizes the correct number on the ID card; otherwise, the machine will not detect anything.

Therefore, ID cards have a wide range of applications and are quite convenient to use. They can generally be used in access control systems, parking management systems, dining out, medical facilities, and other places. Thus, the emergence of ID cards has brought many conveniences to our lives.

Main features of ID cards:
The carrier frequency is 125KHZ (THRC12) or 13.56MHz (THRC13); The data transmission to the card reader is modulated by loading amplitude modulation;
The in-card data encoding uses BPSK phase-shift keying with strong anti-interference capability;
The data transmission rate from card to reader is 3.9kbps (THRC12) or 6.62kbps (THRC13);
Data storage uses EEPROM, with data retention lasting over 10 years; The data storage capacity is 64 bits, including manufacturer, publisher, and user code;
Once the card number is written before sealing, it cannot be changed, ensuring absolute uniqueness and security;
In addition to being packaged in standard card shapes, THRC13 chips can also be packaged into various shapes such as chips according to application needs.

(1) How the ID card works:
The system consists of a card, a card reader, and a backend controller. The work process is as follows:
The card reader sends the carrier signal outward via the antenna;
After the card enters the reader's working area, a resonant circuit composed of inductive coils and capacitors receives the carrier signal sent by the card reader. The RF interface module of the chip generates the power voltage, reset signal, and system clock from these signals to "activate" the chip;
The chip read control module encodes the data in memory through phase modulation, modulates it onto the carrier, and sends it back to the card reader via the card's internal antenna;
The card reader demodulates and decodes the received card return signal and sends it to the backend computer; The backend computer handles and controls different applications based on the validity of the card number.

(2) Types of ID cards:
ID Thick Card: 1.8mm thick, the size of a standard card, currently the most economical RF IC card, comes with an ID number, a portable port, and can screen print logo text information; Standard thin card: 0.8mm thickness, size of standard card, can be offset, screen printing, or photo printing;
Non-standard thin card: thickness 1.05mm; standard cards can be offset, screen printing, or photo printing;

(3) Scope of ID Card Applications:
Compared to contactless IC cards, contactless ID cards do not require insertion or removal, avoiding various faults caused by poor mechanical contact. As a result, they offer advantages such as easy operation, speed, reliability, and long lifespan, making them especially suitable for high-traffic environments. Typical applications: Radio frequency identification fields such as cafeteria meal sales systems, patrol systems, attendance systems, access control systems, and enterprise all-in-one card systems. The THRC12/13 contactless ID card is mainly used for identity identification and addressing control, such as access control, security, attendance, and more. It can also be extended to public places like exhibitions, parks, hotels, restaurants, and other tickets, discount cards, and more. As well as logistics, electronic tags, anti-counterfeiting labels, one-time tickets, and other sectors such as production processes, postal parcels, air and rail transportation, product packaging, and transportation, among many other fields. Although it is only a card reader, it is managed by backend computers, allowing it to be applied to certain areas even when it involves billing management, such as cafeteria meal fee management. For specific applications, cardholders' personal information can be sent to the backend computer, a database is created, and application software is configured. When used, the card number is transmitted to the backend computer via a card reader, which retrieves the cardholder's personal information from the database and then operates according to the specific application, making its application scope extremely broad.
