Frequently Asked Questions: Free & Open-Source RFID Development
Can I test an RFID software application without purchasing physical reader hardware? ↓
Yes. Using the OpenRFID Virtual 2D Simulator on RFID Softwares, you can simulate antenna radiation patterns, tag movement speeds, EPC generation, and test how raw LLRP streams output into SAP or Tally Prime directly in your browser without spending any money on physical hardware.
What is the Low Level Reader Protocol (LLRP) Toolkit (LTK)? ↓
LLRP is an open EPCglobal standard specification that defines the network interface between RFID readers and client software. The open-source LLRP Toolkit (LTK), available on GitHub in C, C++, C#, Java, and Perl, provides developers with code libraries to serialize and deserialize LLRP binary and XML messages across Zebra, Impinj, and Alien fixed readers.
What is an RFID keyboard wedge software and where can I download one? ↓
An RFID keyboard wedge is a background software utility that intercepts raw tag EPC reads from a USB desktop reader or Bluetooth scanner and types them automatically into whatever active cursor window is open (such as Excel, ERP input fields, or web forms) as if typed on a physical keyboard. RFID Softwares provides a free in-browser keyboard simulator and desktop wedge utilities.
What are the limitations of open-source RFID middleware like Fosstrak or Rifidi? ↓
While open-source platforms like Fosstrak and Rifidi provide great architectural foundations for learning the EPCglobal ALE standard, their codebases are largely legacy (Java OSGi) and lack active maintenance for modern cloud environments, Docker containers, and next-generation Impinj E710 / Ex10 chipsets. Production systems typically adopt modern edge daemons like OpenRFID.
How do I read and write NFC tags for free on a smartphone? ↓
Wakdev's NFC Tools (available free on iOS and Android) is the most versatile utility for reading and writing HF/NFC (13.56 MHz) tags. It allows you to program NDEF records including URLs, contact cards, Wi-Fi credentials, and test tag lock bits without specialized hardware.
