I. Performance characteristics of card issuers:

Support card type: MIFARE One S50 card

Function: read and write MIFARE One S50 card.

Functions in IC card consumption system: card initialization, card issuance, recharge, refund, transaction correction, card status correction, card return, etc.

Second, encryption algorithm is adopted between the reader and the RF card, and the card and the device are verified in both directions to automatically detect communication errors.

Anti-collision, can handle multiple cards at the same time.

Has a complete read-write card operation function.

It provides a complete dynamic library, which is convenient for secondary development and can be widely used in occasions such as book borrowing, meeting sign-in, computer room charging, highway charging and so on.

Third, the card issuer is a tool for reading and writing cards, but it is different from card readers, card readers and readers. Card issuers can read, write, authorize and format cards.

Fourth, the main function is to initialize, register and cancel the card in the access control system. The ID card issuer only plays the role of reading cards. At this time, it can be replaced by a card reader. Some IC card systems need to write cards. At this time, you can't use a reading head instead, you can only use an IC card to issue a card. RFID card issuing machine is an UHF desktop reader equipment which is produced to cooperate with users in card issuing management in the background or management center.

5. When the UHF desktop reader is powered on, the buzzer will sound, indicating that it will start working. When the card approaches the RFID desktop writer, the buzzer will sound to indicate that data is being sent. For the same IC card, the interval between two card readings can be set by software. After reading the card, if the IC card is still in the RF card response area, the card reader will not give any prompt or send data, but if the time interval exceeds or different ID cards enter the RF card response area respectively, the card reader will read the card continuously and output data.

6. UHF desktop card reader uses RF induction to read card data, and avoid being close to metal when using it. When the card reader is close to the metal, the radio frequency wave will be absorbed and shielded by the metal, thus shortening the reading distance. At the same time, the installation position of the RFID desktop card issuing machine is far away from equipment such as motors and transformers, so as to reduce the impact on the RFID desktop card issuing machine.
