Contactless RFID card speed up readers' configuration

May 16, 2017 // By Julien Happich
Elatec RFID Systems' TWN4 CONFIG Programmer has been developed as an efficiency-booster for integrators and solution providers who implement large-scale projects, allowing reader settings for a custom-tailored RFID application to be easily applied to the reader through a contactless RFID card.

The TWN4 CONFIG Programmer RFID writing device comes equipped with an application in which settings are made for the TWN4 reader used in the project at hand. The desired setup is encoded onto the contactless RFID cards (TWN4 Configuration Cards) included with delivery; the reader adopts these settings when a configuration card is swiped over it. The TWN4 readers inherently support over 60 RFID technologies in the 125 kHz, 134.2 kHz and 13.56 MHz frequency ranges. The TWN4 Configuration Card configures a device to read only certain technologies or frequencies.

Its greatest advantage is that it can also be used to (re)program infield large numbers of proximity readers via air interface without requiring disassembly of the device or connecting it to a computer. This significantly reduces the configuration effort required for large-scale projects.

The custom settings saved on a configuration card can be traced in order to receive project specific information like the exact technologies used for the project at hand. Moreover, this information is only made available to the individual who programmed the card. No access is provided to any project-specific confidential data. Meanwhile, the ability of the reader to be configured by simply reading the configuration cards does not pose any risk in critical applications: subsequent programming made with a configuration card can be password protected.
