Elektor Digital RFID (E-book)
RFID technology has conquered many areas in which barcodes, magnetic strips and contact smartcards were used previously. Everyday applications, such as electronic ticketing, access cards, debit cards and electronic identity documents would not be possible without this technology.MIFARE is the most widely used RFID technology, and this eBook (PDF) provides a practical and comprehensive introduction to it. Among other things, the initial chapters cover physical fundamentals, relevant standards, RFID antenna design, security considerations and cryptography.The complete design of a reader’s hardware and software is described in detail. The reader’s firmware and the associated PC software support programming using any .NET language. The specially developed PC program, “Smart Card Magic.NET”, is a simple development environment that supports sending commands to a card at the click of a mouse, as well as the ability to create C# scripts. Alternatively, one may follow all of the examples using Visual Studio 2010 Express Edition.Finally, the major smart card reader API standards are introduced. The focus is on programming contactless smartcards using standard PC/SC readers using C/C++, Java and C#.

RFID Starter Kit for Arduino (incl. Uno R3)
Modern electronic experimenter kits contain modules that just plug together rather than individual components so that now we can quickly get modules talking and then decide in software how the system behaves. Thanks to the wide selection of software library functions we can have a sketch up and running in no time. These kits are worthy successors to the bags of loose components that were a feature of earlier experimenter’s kits. Electronic newbies, practicing engineers and old hands alike are sure to find that these kits interesting. The range of components is sure to get you thinking what you could use them for and they are a good way to build on your existing knowledge. You’ll have no excuse not to go on to design and build your own system! The ‘RFID Starter Kit for Arduino’ comes in a handy case and contains over 30 state-of-the-art components, devices and modules. Although it contains an RFID receiver module along with two RFID tags in the form of a credit card and key fob, the case is an Aladdin’s cave with loads of other useful components.

Elektor Digital Home Automation Projects with Arduino (E-BOOK)
An Arduino board has now become ‘the’ basic component in the maker community. No longer is an introduction to the world of microcontrollers the preserve of the expert. When it comes to expanding the capabilities of the basic Arduino board however, the developer is still largely on his own. If you really want to build some innovative projects it’s often necessary to get down to component level. This can present many beginners with major problems. That is exactly where this e-book begins. This e-book explains how a wide variety of practical projects can be built using items supplied in a single kit together with the Arduino board. This kit, called the "RFID Starter Kit for Arduino" (SKU 17240) is not just limited to RFID applications but contains more than 30 components, devices and modules covering all areas of modern electronics. In addition to more simple components such as LEDs and resistors there are also complex and sophisticated modules that employ the latest technology such as: A humidity sensor A multicolor LED A large LED matrix with 64 points of light A 4-character 7-segment LED display An infra red remote-controller unit A complete LC-display module A servo A stepper motor and controller module A complete RFID reader module and security tag On top of that you will get to build precise digital thermometers, hygrometers, exposure meters and various alarm systems. There are also practical devices and applications such as a fully automatic rain sensor, a sound-controlled remote control system, a multifunctional weather station and so much more. All of the projects described can be built using the components supplied in the Elektor kit.
