The OpenBeacon project was founded in 2006 by the Berlin located company Bitmanufaktur GmbH as an open platform for active RFID applications operating in the license free 2.4GHz ISM band. OpenBeacon is based on Open Source software and a very flexible and reprogrammable lowcost Open Source RFmodule. The firmware sources and hardware schematics are available under GPL license. We encourage the development of new ideas for OpenBeacon setups and firmware improvements.
This wiki collects and maintains all user and developer documentation of the Open Source and Open Hardware Active 2.4 GHz RFID reader system and our Open Source and Open Hardware active RFID tags.

Mifare and DESfire RFID modules from company Stronglink enable to use advanced RFID technologies while maintaining a very affordable price.
MIFARE ultralight, MIFARE 1k, MIFARE 4k and MIFARE DESfire are known technologies of RFID enabling to use various application, store various data and other functions. From this reason, they´re largely used in admission systems, loyalty programs, goods tracking and many other segments. From the security point of view, mainly the DESfire system with the DES/AES encryption excels. New 13,56 MHz Stronglink modules in our portfolio – SL025M, SL030, SL031, SL032, SL040 and SL040A enable to use these technologies and they are relatively easily applicable because of more reasons. Firstly, they are available in more versions with UART, I2C, RS232 as well as USB interface, they are certified (CE and RoHS) and the producer provides an above-standard development support.
Usage of modules is also simplified by their low power consumption and a relatively very low-profile construction with the height of only few mm. An important factor – the price, also says in favor of Stronglink modules, because they´re available for relatively very competitive prices. For the development support, there are also available source code examples for various microcontroller families. Further information will provide you the SL025M, SL030, SL031, SL032, SL040 and SL040A user manuals and AN100721, AN101203 and AN110221 application notes.

Compact RFID modules ID12 and ID20 can be marked by right as simple to use and reliable RFID components working with 125 kHz frequency.
Both types contain an internal antenna, thus eliminating the need of its design, production and tuning of a resonant circuit. Further, modules ID12 and ID20 contain all necessary circuitry, that´s why to produce a working RFID device, it is only necessary to connect these modules to a control unit – most often to a microcontroller. It can be said, that ID12 and ID20 represent a ready-to-use solution for a very affordable price.
If you take a look at the ID12/ID20 application circuit, you´ll find it extremely simple and also the same for both types. The main difference for both types is the range – ID12 has a 12+cm range and ID20 has 16+ cm. Corresponding to their range, has ID12 smaller dimensions and a lower power consumption than ID20.
In case, that you prefer an external antenna, you can use the ID2, module delivered with a wire-wound antenna, which only needs to be suitably placed and connected to the module. For some applications also the version of ID12 with an USB interface can be convenient – ID2-ID12USB, which can be connected directly to a PC. In case, you prefer Mifare RFID (13,56 MHz), you can use the ID20MFIA module.

We want to show you how to use the popular Arduino to produce a device capable of recognizing passive transponder (TAG). But this is not the usual RFID key, because the system can activate a relay if a recognised TAG is read, but also we took the opportunity to make an application that use cloud-computing. The basic version, which is a simple key relay consists of an Arduino and the RFID shield based on a ID-12 of Innovations: placing a transponder already learned, the relay is activated. The extended version of our project uses an Arduino, the RFID Shield and the Ethernet Shield with which we can access the Internet and stored, using the Google Docs service, the transponder data.

I wanted to make an easy and secure way to enter my garage. RFID was the best way to unlock my door, even with my hands full I can unlock the door and push it open! I built a simple circuit with a basic ATMega 168 arduino chip and a ID-20 RFID reader to control an electronic door lock.
The circuit consists of 3 separate parts, a Reader to read RFID tags, a Controller to accept data from the reader and control the output of the RGB LED and the Electric door lock. The door lock is first installed in a door and tested with a 9v battery to ensure correct installation. In most cases you want a Normally Open circuit on the door lock, or Fail Secure. This means the door stays locked when no current passes through it. When 12vDC is passed through the electromagnet in the door lock, a plate in the lock gives way and allows the door to be pushed open freely.

Read and write 13.56 MHz RFID cards with OpenPCD:
OpenPCD is a free hardware design for Proximity Coupling Devices (PCD) based on 13,56MHz communication. This device is able to screen informations from Proximity Integrated Circuit Cards (PICC) conforming to vendor-independent standards such as ISO 14443, ISO 15693 as well as proprietary protocols such as Mifare Classic. Contactless cards like these are for example used in the new electronic passports.

RFID antennas are traditionally produced by etching, but a new process developed by Walki, a manufacturer of technical laminates, aims to displace etching by laser cutting. The process uses paper as the substrate and eliminates the need for liquid chemicals, making process residue easily recyclable. Laser cutting also accelerates the design to production cycle and allows extremely precise fabrication of circuit board patterns. The finished antenna, consisting of just paper and aluminium, is fully recyclable.
The new technology is dubbed Walki-4E where 4E stands for efficient, exact, ecological and economical and is based on a laminate of aluminium on a paper substrate, with the aluminium foil cut in patterns using a laser. It can be used to produce any type of flexible circuit, ranging from RFID antennas to radiators and flexible displays. The first product to be launched using this technology is Walki-Pantenna, a UHF RFID antenna. [via]

ID 12 and ID 20 are miniature modules of RFID readers with operating frequency 125KHz. Their operating distance is from 12 to 16cm and depends on transponder type and size. ID tags type EM4001 and other types compatible with them (64 bit Manchester and Modulus coding)can be used with mentioned RFID readers.
Readers need only 5V power supply for their operation, without any other external components. To indicate their functionality there is a possibility to add LED and buzzer. Both readers are compatible with ASCII, Wiegand26 and Magnetic ABA data formats.
