Advantages of the Smart Card
1. High reliability, long service life. There is no mechanical contact between the card and reading and writing machine, thus avoid the fault caused by the contact with reading and writing machine. This is not only convenient for the card to print, but also to improve the reliability of the card use. Especially in some conditions with big interference environment, non-contact smart card is more outstanding. 2. Easy and fast to operate. Due to the use of non-contact communication method, the reading and writing machine can operate the smart card in a certain distance, so users don't need to swap cards, and there is no direction when using the smart card, the user will need not to take out the card from their wallet then can brush card, this has greatly improved the ease of use and the speed of system operation. http://www.great-card.com specializes in producing and marketing of PVC card and smart card at competitive price and professional after-sale service.
