2025-07-25 00:00:00 SAMM® ACCESS CHECKER is an application designed to control access to buildings, events, unlock doors and can also be used as an employee entry and exit clock. You can use it, for example, to control the access of clients to a gym, validating only active clients and blocking clients who are not up to date. It can be used without the need for an Internet connection, allowing data to be stored locally or you can also configure a server manually using a database engine installed on a computer within the local network. It can be used on tablets installed on the wall and configured to read cards or credentials of officials, clients or direct QR reading on phone screens. QR codes can be generated and displayed on the screen when creating a user, this same QR can be used to print on official credentials or client cards. Using a MEGA 2560 plate you can open and unlock turnstiles, doors and security barriers, even RFID devices for vehicles.
