For you, the ideal package is the basic package with the optional User Module. If you do not have a static public IP address on your business, you will need access to the external access service, or place the database on our external servers (to be able to connect from anywhere that has an Internet connection). You install Elasyc on your older computer and activate all modules (User, Terminal, and Server). You will install Elasyc on your notebook and activate the User Module on it. You will still have 1 module User who can give you, for example, Accounting. For the SMALL license package you will need 1 RFID card reader and RFID keycards in number as needed. If you also want to record employee photos as they are attributed, you will need any webcam.
