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 book 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#.

SparkFun SparkFun RFID Qwiic Reader
Plug a reader into the headers, use a Qwiic cable, scan your 125kHz ID tag, and the unique 32-bit ID will be shown on the screen. The unit comes with a read LED and buzzer, but don't worry, there is a jumper you can cut to disable the buzzer if you want. Utilizing SparkFun's handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins if you prefer to use a breadboard. Utilizing the onboard ATtiny84A, the Qwiic RFID takes the six byte ID tag of your 125kHz RFID card, attaches a timestamp to it, and puts it onto a stack that holds up to 20 unique RFID scans at a time. This information is easy to get at with some simple I²C commands.

Elektor Digital Radio Builder's Book (PDF)
From Detector to Software Defined RadioRadio frequency (RF) technology is one of the areas which still allows putting your own ideas into practice. Countless circuit variants with special objectives allow space for meaningful experiments and projects. Many things simply aren’t available off the shelf. Crystal detector radios without their own power source, simple tube receivers with a touch of nostalgia, the first reception attempts at Software Defined Radio, special receivers for amateur radio, all this can be realized with little effort and as a perfect introduction to RF electronics.For a long time, radio construction was the first step into electronics. Meanwhile, there are other ways, especially via computers, microcontrollers, and digital technology. However, the analog roots of electronics are often neglected. Elementary radio technology and easy-to-do experiments are particularly well suited as a learning field for electronics because you can start with the simplest basics here.But the connection to modern digital technology is also obvious, for example, when it comes to modern tuning methods such as PLL and DDS or modern DSP radios.This book aims to give an overview and present a collection of simple RF projects. The author would like to support you to develop your own ideas, to design your own receivers and to test them.
