Let's say I have a smart pen. It has a microcontroller that can communicate with my server. I want to have a really small and flat gadget (let's call it The RecieverReceiver) that when you touch it with that pen, you save a 16 character string on it. The pen also has a GET mode in when I touch The RecieverReceiver, it sends the string stored on that RecieverReceiver to the server.
My question is, what is the best way to make that Receiver and the tip of the pen? Bluetooth isn't preferred, because there will be multiple Receivers in a small area. My thinking was also some sort of a scanner at the tip of the pen, but I don't want the receivers to be ugly looking with some codes printed on them (that is still a possibility). I think the best solution would just be some sort of identification for each receiver so that the pen can identify it just by touching it.

What is the best way to achieve triggering a function on device contact?
