  IC cards are often seen in our daily lives. Its development has experienced contact memory cards and encryption cards, and is now developing in the direction of  contactless cards  and CPU cards. The wireless IC card uses a non-contact method, which uses radio frequency technology to achieve communication between the radio frequency card and the read-write device. Compared with early or simultaneous identification technologies such as bar codes and magnetic cards, it has the advantages of large working distance, no contact, and fast information processing speed. Therefore, in addition to being used in confidential and financial products, this high-tech product can also be widely used in the fields of household appliances, identity certificate control, anti-theft alarm, electronic anti-counterfeit labels, and  rfid animal ear tag  classification.The advantages of wireless radio frequency cards are described below.   Radio frequency identification technology is abbreviated as RFID, whi

  The contactless IC card is also called a radio frequency identification card, and is composed of an IC chip and an induction antenna. It is encapsulated in a standard PVC card. The chip and the antenna have no exposed parts.   RF card is a new technology developed in the world in recent years. It successfully combines the  applications of rfid technology  and IC card technology, ending the problem of passive (no power in the card) and contact-free. The RFID card is a breakthrough in the field of electronic devices. The card is close to the surface of the reader at a certain distance (usually 5-10mm), and the data is read and written through the transmission of radio waves.   1. The non-contact IC card and the card reader use radio waves to complete the read and write operations. The communication frequency between the two is 13.56MHZ. The non-contact IC card itself is a passive card. When the reader performs reading and writing operations on the card, the signal emitted by the reader

  The radio frequency identification card is mainly produced by contactless IC card identification technology. Not only certain technical support is required, but also strong card-making equipment is needed to ensure that no mistakes are made in the process of making RFID cards.   Radio frequency cards are divided into low frequency cards and high frequency cards ( hf card ). The low-frequency RFID technology below 13.56MHz has accumulated more than 10 years of mature experience in the industry. At present, the RFID technology located in the middle and high frequency bands is the most concerned in the industry. In the field of high frequency, domestic companies have gradually matured their technologies and are actively promoting the application of various systems. At present, the demand for RFID cards  in China is very large!   As a more sophisticated product in the smart card, the RF card is currently used in traffic management, security system, personnel attendance management, member

  The rapid development of RFID technology makes it more advanced than other technologies. SHANGHAI STAR introduces the seven advantages of  RFID cards .   ① Easy and fast to read No light source is needed to read the data, and it can even be carried out through the outer packaging. The effective identification distance is greater. When using an active label with its own battery, the effective identification distance can reach more than 30 meters.   ② Large data capacity The two-dimensional barcode with the largest data capacity (PDF417) can only store up to 2,725 digits; if it contains letters, the storage capacity will be less; RFID tags can be expanded to 10K according to the needs of users.   ③ Tag data can be changed dynamically The programmer can be used to write data to the tag, giving the RFID tag the function of an interactive portable data file, and the writing time is less than printing a barcode.   ④ Better security Not only can it be embedded or attached to products of dif

  The  contactless IC card  is a new type of smart card with the same functions as the contact ID card and IC card. It only needs no power supply, and the receiving antenna draws power from the magnetic field of the reader, and calculates the data and feeds it back to the reader. So what are the advantages of contactless IC card compared with contact IC card? Compared with contact IC cards, contactless cards have the following advantages:   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, failures caused by rough insertion of cards, insertion of non-card foreign objects, and poor contact due to dust or oil. In addition, there is no exposed chip on the surface of the contactless card, and there is no need to worry about the chip falling off, electrostatic breakdown, and bending damage. It not only facilitates the printing of cards, but also improves the rel
