CardExchange® Business Edition has all the features of standard Producer Professional and includes MIFARE® Classic encoding and biometeric. It is also the first edition with the ability to run on a network with concurrent users. Business Edition has the ability to centrally manage all client licenses and shared data in any location on your network. You do not need a dedicated server. Centrally sharing the data over a network allows for an "update=one, update=all' solution. You only need to buy one Master License and add client licenses as you need them. You can load CardExchange® Business on as many clients as you would like, and the amount of client licenses you purchase will determine how many concurrent users you can have.
