I can’t say I have ever in my life written about a prayer gadget before. However, this is now changing as I came across this prayer device which uses RFID technology. In some churches there is a tradition of lighting candles during a prayer. This device is named “for this we pray” and has RFID technology that lights up a wall mounted shrine which is modelled around a stained glass window effect. Several prayer cards can be chosen from and when you swipe one past the prayer gadget a light lights up. As more prayers are read out and swiped past, the more lights are then lit up.
Below is a video of the prayer device in use.
