  Contactless IC card , also known as radio frequency card. It successfully solved the problem of passive (no power in the card) and contact-free. It is a major breakthrough in the field of electronic devices. It is widely used in electronic wallets, smart cards, campus cards, channel charge control, automatic bus ticketing, automatic parking fees, canteen sales, attendance and access control, scenic spot charges, hospital charges, etc. Cards include membership card, access control card, charge card, consumption card, bus card, student card, hospital visit card, scenic ticket card, point card, stored value card, shopping card, water card, etc.   Contactless IC cards are mainly MIFARE ONE cards (that is, M1 cards). M1 card main indicators: The capacity is 8K bits, the EEPROM is divided into 16 sectors, each sector is 4 blocks, each block is 16 bytes, block is the access unit, and each sector has an independent set of passwords And access control. Each card has a unique serial n...

The contactless IC card , also known as the induction card, was born in the early 1990s. Because of its incomparable advantages that magnetic cards and contact IC cards do not have, it immediately attracted wide attention as soon as it came out, and was promoted and applied at an alarming rate. The contactless IC card is composed of an IC chip and an induction antenna, and is completely sealed in a standard PVC card with no exposed parts. The read-write process of the non-contact IC card is usually completed by radio waves between the non-contact IC card and the reader. The contactless IC card itself is a passive body. When the reader reads and writes the card, the signal emitted by the reader is composed of two parts superimposed. One part is the power signal. After the signal is received by the card, it resonates with its own L/C, generating an instant energy to supply the chip with work. The other part is to combine the data signal and direct the chip to complete the data, modifi...

Most of the parking cards used in the parking lot are contactless IC cards . Many people will use them, but they do not know how these cards are produced, and what are the key technologies. Next, SHANGHAI STAR TREND takes you to discuss the manufacturing of the contactless parking card and the chip packaging process. 1. IC card RF technology (1) Take a passive design. A set of electromagnetic waves of fixed frequency needs to be sent by the reader to the RF card, and the DC voltage required for the chip to work is generated through the circuit in the card; (2) A specially designed antenna is required in the card and is embedded in the card; (3) A good anti-interference performance must be ensured, and an anti-collision circuit must also be provided. 2. Low power consumption technology Whether it is a non-contact IC card designed in an active or passive manner, one of the most basic requirements is to reduce power consumption to increase the life of the card and expand the appli...

(1) High reliability There is no mechanical contact between the contactless IC card and the reader, which avoids various failures caused by contact reading and writing. For example, due to rough card insertion and the insertion of non-card foreign objects, dust or oil can cause malfunction due to poor contact. In addition, there is no bare chip on the surface of the non-contact card, so there is no need to worry about the chip falling off, electrostatic breakdown, bending damage and other problems. It not only facilitates card printing, but also improves the reliability of card use. (2) Easy operation Due to contactless communication, the reader can operate the card within 10CM, so there is no need to insert the card. It is very user-friendly. There is no directionality when using a non-contact card. The card can sweep the surface of the reader in any direction to complete the operation, which greatly improves the speed of each use. (3) Anti-conflict The contactless card has a...

PVC transparent cards are made of transparent materials. The front and back surfaces of the cards are partially transparent, and the logo can be transparent. It can be fully transparent or translucent. The neat transparent plastic card is stylish and elegant, and looks very high-end. Such cards are mainly used in industries such as shopping malls, supermarkets, medicine, catering, entertainment, health care, leisure, hotels, beauty, hairdressing, clothing, fitness, automobiles, photography and so on. It is usually made into a premium supreme membership card, because membership uniforms are a popular service management model, which can increase the customer return rate and increase customer loyalty to the enterprise. Many service industries have adopted this service model, and membership can now be seen in various industries. The form of membership system is also mostly represented as a membership card. Membership cards and VIP cards can increase customers' willingness to purchas...

(1) Convex code: Convex code is the most common type of coding seen in PVC plastic card . You can see that many cards on the market have convex codes. These convex codes can be numbers or capital letters. The coding process is relatively simple, and there are generally no major problems (except for the position of the coil in the chip card). (2) Printing code: Printing code is more convenient, and basically there are no restrictions on coding. It is the most convenient way to code, and the cost is low. (3) Laser codes: Laser codes are relatively rare, and their cost is relatively higher than other coding methods. The color is single, and it can only be a golden yellow laser code. But its advantage is that it is durable and never fades. (4) Gold / silver flat codes: These two types of codes look pretty and high-end. According to the color design of the customer's card, you can choose gold or silver. It should be noted that if the customer card happens to have UV oil design, it i...

The general term of inductive IC chip card is called radio frequency IC card, M1 card, and it is also an IC card that is often used in people's lives. Inductive IC chip card is a combination of radio frequency identification technology and IC card technology, breaking through the problem of passive (no power supply in the card) and contact-free in the field of electronic devices. Eight characteristics of inductive IC chip card 1. There is non-mechanical contact between the card and the reader. 2. There are no exposed devices on the surface of the card, and the IC card will not be damaged due to contamination or bending. The card itself is a passive part, small in size, durable and reliable. 3. The reader does not need a card holder and can be completely sealed in the box. 4. There is no direction during use. The card can sweep the surface of the reader in any direction to complete the reading and writing work. 5. The reader communicates with the IC card via antenna communicat...
