GPRS with Web Server Based Attendance System
GPRS with Web Server Based Attendance System
The Conceptual Communication Diagram
As shown in the conceptual diagram, there are 4 major components, which are:
a.
FingerTec deviceterminal installed at site with GPRS activated simCard.
b.
GPRS coverage (requires GSM/GPRS SIM card)
c.
d.
TCMSV2 (a software installed to a local PC to retrieve information from FingerTec Web Server)
The Communication & Data Transfer Step 1 To install and activate GPRS connection
Installation of Deviceterminals in a site is similar to normal installation. The only additionis the GSM/GPRS SIM card. You must apply a GSM/GPRS SIM card from your local service provider, and make sure it is activated with GPRS feature.
You must configure theterminal after inserting the GSM/GPRS SIM card.device provides the tool for you to configure the GPRS connection. This is the information required to configure the GPRS connection in terminal (details explanation on each data field is explained in the GPRS setup manual).
Step 2 To install Web Server In headquarters, a dedicated PC is required as Web Server. The Server requires a fixed IP address to connect to WAN (Wide Area Network). TheWeb Server communicates with terminals via GPRS. Step 3 Start to run Web Server
TheWeb Server must run to connect toterminals to retrieve information. The Web Server is protected by password.When the GPRS connection is established, you can see the details of terminal on webserver screen.You will see all information of terminal be displayed on screen. You can check the total of users, fingerprints, transaction logs etc stored in the terminal.
You can manage and check all terminals in Web Server. All operation are done online and immediate effect to the terminals.
You can check any activities at any terminal, such as terminal is power on/off, enrolment of users, administrator login into system etc. All activities are recorded by date and time for reference. Step 4 Enrolment and Verification at terminal
After the configuration, you can start to enroll users into the terminals. During enrolment, user enrolls fingerprint, password or card at the terminal. His/her information (user ID, fingerprint, password, card ID) be stored in local memory of terminal.
The enrolment information (user ID, card ID) will be sent to Web Server via GPRS and viewed in Web Server. This is to inform administrator a new user has been enrolled into a terminal. It shows the administrator (showed by User ID) who enrolled the new user.
Result of verification are kept in local memory of terminal.The terminal sends the result of verification (or transaction log) to Web Server immediately (similar to the enrollment process). Administrator can always check who is the user report attendance, and what time the user is reporting for attendance. The data transfer is in real time right after verification is completed at terminals. Therefore administrator can always receive the latest transaction logs for evaluation.
If the verification is failed (improper verification or trail error),The terminal will send the information toWeb Server to alert the administrator to check the terminal.
Any changes done to the internal settings of terminals are recorded and send to Web Server for review. This is to secure the terminal from any improper or unauthorized settings.
