If on one side the automatic RFID identification techniques based on passive tags (without own supply) are simples and economics, RFID solutions based on semi-passive tags (or battery-assisted), in which a little battery is used for amplify the signal to the reader, or completely active solutionst that used large batteries and integrates a real time clock, enable to improve the system’s performance and in particular to improve the range of transmission. Furthermore, active tags allow to:
- actiovate on command received by the reader or trnsmit at prefixed time intervals;
- memorize events log in a memory, larger then that avaible in passive tags;
- connect to sensors and devices in GPS technology for implements monitoring, localization and real time tracking solutions;
The more features involve an higher price than passive RFID tags and are used (and reused) for goods that allow a rapid recovery of the initial investmnent.
EPROJETECH offers a complete range of readers and tags (possibly equipped also with integrated sensor), able to satisfy every necessity in commercial, industrial and personal purpose fields.
