This design uses RFID tag technology to enable low-cost, battery-free, and easy-to-install home security systems.

If you can dream it, Arduino can help you build it -- perhaps with a dash of MakerBot thrown in for good measure. The latest homebrew project to hit the ol' inbox sounds an alarm whenever you ...

"It is hard to overstate how vulnerable the system is, and it's even more shocking that this exact model is currently used at over 1,100 universities, and in nearly 100,000 classrooms," Nair said.

The authors propose the use of RFID technology and an Arduino board for the same. Every product will have an RFID (Radio-Frequency IDentification) tag (instead of barcodes being used conventionally).

The Arduino acts as the brains of the operation while an off-the-shelf NFC/RFID reader module is used to read the RFID tags. To add new keys to the system, [Jason] simply swipes his “master ...

These tags are then inserted into holes on the device. When an RFID tag is placed into the jukebox, it communicates with the Arduino system, which in turn connects to the user’s Spotify account.
