Michael Paholski was tasked with creating a modern rendition of an employee punch-clock, and turned to Arduino as the base for his solution. By using a Freetronics EtherTen, an after market NFC shield and related circuitry his goal has been successful. Over various articles the project is described from the idea phase through to the culmination of the final product. When completed it can record the card data, the direction of entry on the card and alter this, and send required data to an external database.
If you found the project above interesting - but not sure how to start with Arduino - then the best way to learn is with our Experimenter's Kit for Arduino:
The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. However we don't leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words - this is everything you need to get started for a fun range of electronics and Arduino related projects!
