For makeing this led indicator for your wallet you will need one CR2016 lithium battery,one small magnet and led diode.
How it works,when there is no money in wallet the led is on and mean to put cash in wallet,when cash is inside wallet the led is off,circuit is very simple but great :)

Wonderful. Why you do not build a red led for indication? :)

I know that red led is more efective but at that moment I have just green smd led.
