This induced AC voltage is rectified to provide a voltage source for the device. Passive RFID tags utilize an induced antenna coil voltage for operation. While the higher number of degrees means a bigger wave coverage pattern it also means lower strength of the signal. The field coverage of the wave and also its signal strength is partially controlled by the number of degrees that the wave expands as it leaves the antenna. The RFID antenna propagates the wave in both vertical and horizontal dimensions. ![]() Some RFID reader with integrated antenna with 0.5cm to 100cm distance. RFID reader 125khz/13.56Mhz/ with USB or ethernet or RS232 RS85. The external antenna reader designed for passive RFID reader get long-range, like 1m range 2m range or 10 meters.īut the integrated reader with short read distance. An rfid reader writer software has two parts:Ī RFID reader and antenna, some RFID reader with external antenna, they are rfid readers what is working in the frequency of 860-900mhz long-distance or 13.56 MHz long-range. RFID (Radio Frequency Identification)with a unique identification number for each item and just like a bar code card/label or magnetic strip card, the RFID tag/card must be scanned by a passive RFID reader device and retrieve the identifying information. ![]()
