1. Introduction to long-distance D card
The frequency of long-distance D card is generally. What is currently used in the market is a passive, unique serial number D card. The manufacturer has solidified the serial number and cannot change it before the product leaves the factory. The long-distance D card is a transitional product that appeared to meet the requirement of long-distance reading of the internal serial number of the D card. Although it is not strong in security, it is relatively low-priced and is currently widely used in parking lots, passages and other systems.
2. Common technical parameters of long-distance D card
, Working frequency:
, Internal serial number: bytes
, Reading distance: .-.meter requires special equipment The accurate distance read by the long-distance read head is related to the performance of the long-distance read head.
3. Long-distance D cards can be distinguished by thickness
Thick cards: Thickness. Thick cards can be sprayed with D card numbers in various formats, can be screen printed, and can be printed with self-adhesive stickers or color printing. Put on the transparent film.
, Standard thin card: Thickness. It can be double-sided color offset printing. Photo printing can be plain code or laser or jet printing D card internal code in various formats or self-programmed serial number. The reading distance of long-distance D-thin cards is generally slightly lower than the reading distance of long-distance D-thick cards
