Tamtron GSM access control terminals control electronic locks and allow you to open doors with a phone call. There is no need to carry separate keys as the mobile phone you carry with you acts as the key. GSM510 acts as a part of a larger access control system, and its transactions can be inspected and monitored with access control software. Meanwhile the GSM520 is a wholly independent and stand-alone access control device that does not require a connection to a computer.

The access rights are managed by secured SMS messages that can be send wherever the administrator is. It is even possible to lock the system from users with a single SMS message. The user is no longer needed to sign off a key at the reception.

Even when the user is in a different country, the administrator can modify the rights and save time, money and effort. It is also possible to control the access by counting the number of entrances. Therefore, GSM 520 is an ideal solution for services such as a fitness center where a user can purchase a given number of entries. The I/Os are used to control the lock and other electronic devices.
