Attendance Recording System is one of the prime products that Fortuna Impex produces. Bar code technology has its competitive edges: non-contact sensing, long MTBF, durable, and easy to make. Access control systems using bar code technology can help prevent unauthorized access.

The scanned serial data needs to be sent to the control room. But the maximum RS-232 connection distance is only 15 meters, and it can only establish one-to-one connection. If there are a large number of card readers in a system, it will need more PCs to establish connections, making PC cost excessively high. And the wiring cost will be high as well, and customers will complain about the low pulling speed when RS-232 signals are changing to RS-485 signals. In order to lengthen the connection distance, and reduce PC and wiring cost, NE-4000T Embedded Network Enabler was chosen to network enable card readers instantly, allowing serial data to be transmitted via the Ethernet network.
