Well tech tinkerer Joe Desbonnet has whipped up what he dubs "poor man's NFC" using an Arduino, some magnet wire, and any compass-equipped Android smartphone (which is almost all of them).

Connections are pretty simple and only a few wires. Connect the VCC and GND of the sensor to the 5V and GND pins of the Arduino. Then connect the output to the Arduino’s D2 pin. Here's how the ...

Joe Desbonnet combined an Arduino microcontroller with a magnetic coil to create what he calls the “Poor Man’s NFC”. The hack allows for a one-direction, ...
