Long-distance ID card is introduced
Induction distance:
0.7 1.2 (cm) chip: CPU card
Time to read and write: 1-2 (MS) storage capacity: 5 k (bits)
Packaging materials: PVC/PET:
Wipe life: more than 100000 (times) power supply mode: passive card
Specification: 85.5 * (54 mm) carrier frequency: high frequency radio frequency card
A, the long-distance ID card
The frequency of long-distance ID card for 125 KHZ. Used in the market now is a more passive, the only ID card serial number, manufacturer before the products leave the factory has the serial number, curing may be changed. Long-distance ID card is in order to meet the remote reading internal serial number and ID card of the transition stage of a product, although the safety is not strong, but the price is low, the current is applied in the parking lot, channel system, such as common.
Second, the ID card of the commonly used technical parameters over a long distance
1, the working frequency: 125 KHZ
2, the internal serial number: 5 bytes
3, read distance: 0.7-0.7 meters, need to be equipped with specialized remote reading head, read the accurate distance related to the performance of the remote reading head.
Three, the long-distance ID card according to the thickness of redistribution
1, the thick card: the thickness of 1.8 mm, thick card can be sprayed in a variety of formats, ID card number can be screen printing, can print stickers or other color printing poster after the transparent film.
2, the standard thin card: the thickness of 0.8 mm, can double color offset printing, printing, photo, spray can PingMa or laser or printed in a variety of formats ID card or editing the serial number of the internal code being used. Thin long-distance ID card reading distance, usually slightly below the thick ID card reading distance over a long distance
