RFID Technology

Radio-Frequency IDenification (RFID) is a technology that allows for wireless communications between a tag and reader, commonly used for inventory tracking or component identification to a control system. Various frequencies of operation exist for different purposes, and tags may take any number of forms, such as ID badges, key chains, printed flat labels, and many others. Components can be broken down as a Tag (Transponder), a Reader, an Antenna, and sometimes an Interface. The Reader and Antenna are enclosed into a single housing or are 2 separate components.

RFID Interfaces​

Interfaces typically manage a network of Readers (Smart Antennas) and provide communication protocols specific to a particular PLC manufacturer like Ethernet/IP & DeviceNet (Allen Bradley PLC’s), Profibus & Profinet (Siemens), Modbus RTU and Modbus TCP (Modicon) although standard TCPIP Ethernet and serial communications can also be offered.

RFID Readers

RFID Readers vary from OEM modules to robust dedicated or networkable models providing communication protocols of Allen Bradley’s Ethernet/IP, DeviceNet, Siemens Profibus & PROFINET, Modicon Modbus RTU & Modbus TCP, CANopen, as well as USB, Serial & TCPIP Ethernet. Readers translate the 1’s and 0’s of Tag data into languages another machine or human can understand, like TTL or ASCII bytes. Readers can have other functions, like I/O, sound a horn, illuminate a light, etc., or even logic tasks. Most often Readers are capable of serial (RS232, RS485, RS422), USB, TTL, Wiegand and Ethernet communication protocols.

RFID tag


There are two types of tags: Passive Tags and Active Tags. Passive tags do not have a battery and powered by the Reader/Antenna signal. Active tags contain a battery and are self powered. Passive Tags carry data and are Read Only (RO) or Read Write (RW) and lie dormant until it is activated by the RF signal of a Reader. Upon being woken or excited by the Reader, the Tags begins to transmit it’s data back to the Reader. Tags typically have an infinite life in terms of being read, and a finite life in terms of the amount of writes. RFID Tags come in a variety of options from disposable labels to rugged high temperature versions. Depending on your application, you can choose tags and labels with temperature sensors that sends this data to the Reader.

RFID Handhelds

Handheld RFID Readers offer a way to remotely be able read Tags, saving the data or further transmitting RFID Tag data via WPAN or Bluetooth, or via a wired USB connection. They are convenient for testing Tags or used has a hand held for RFID Inc. LF 125 KHz RFID Tag Programmers, which are easy to use and require no software.

RFID Programmers​

RFID, Inc’s LF 125 KHz Desktop Programmer is a convenient tool for programming RFID Tags and powered via USB. They also offer USB or RS232 Desktop Programmers and don’t require software or future updates regardless of your operating system. RFID, Inc. also offers a free terminal program of its own.
