Whether an IC card can be used in two access control systems
There are two ways, one is the two access control system from the same host control.Other way is to separate the door card in the two access control system (that is, open the card function, the need for two access control systems using the same brand of card)
Ic card can be a special card in the access control system, there is no encryption is not encrypted, access control system, the main IC card card number, IC card is not a brand of non-brand, they are unified standard factory, but you use the district Is the card to access the words, to reconsider
Two cells with a district, each cell with a card in another district access control system in the registration once, open access control, so that after the merger of a district, the card can be used in the two access control system, so more trouble. If the two access control system into one, all the card information to open all the access control so convenient.
