Nohmad 2.1 - iButton Terminal
Economic to install and easy to use, the Nohmad 2.1 provides employers with an instant snapshot of where their workers are at any given moment. The worker either places their finger or places their token - about the size of a pound coin, and just as robust - against the base station.
The Nohmad 2.1 range of terminals works to provide employers with details of their workers actions at any given moment.
The information confirming the identity of the employee and the date and time of their arrival or departure, is then sent to a designated server where the data is recorded and can be analysed as required.
Traditional attendance terminals operating in real time, generally need to be connected to a physical communications network, often the user's LAN. However the Nohmad 2.1 does not.
These advantages, along with its modest cost, make it an ideal device for industry sectors supplying low margin services across multiple sites, which also require both accurate and immediate attendance records.
How it works
The Nohmad 2.1 Terminal brings together a variety of modern technologies. Employee identification is provided either by the use of an iButton™ or a Fingerprint Swipe reader, linked to GPRS wireless networks used by mobile phones worldwide.
GPRS is a data service available to users of GSM (Global System for Mobile Communications). Unlike a normal phone call, GPRS connections are 'always on' and are charged by the amount of data transferred instead of the length of time the call is made for.
This is ideal for a real-time device like the Nohmad 2.1, where data has to be sent to the host immediately but occurs at irregular intervals. Each iButton™ or fingerprint credential has a unique and unalterable identity which is used by the Nohmad 2.1 for identification. A user simply touches their iButton™ or swipes their finger onto the Nohmad 2.1 and the credential is read instantaneously. Visual and audio indicators provide user feedback.
The Nohmad 2.1 adds the current date and time to the user's ID and sends this data as a TCP/IP message to a host server, anywhere in the world. The information is usually available for processing within moments.
If the GPRS network is temporarily unavailable, Nohmad 2.1 stores the data in internal memory and then sends the stored data as soon as a network connection is re-established. NOTE: Performance will be affected by prevailing network coverage and conditions.
