Basin, how many fliers are there at one time? Probably a lot from the sound of it on other threads.

about a simple board with plexi glass covered slots to put an ama or club membership card into, or maybe a drivers licence. That way you would know who it is and it would have a picture on it. They can put the card into the slot, and maybe have a slider on it so they can close it or a small pin on a chain that locks the card in so the wind or something else can't take the card out without removing the pin. That way the card can't fall out. If you have minors flying, they can use a school ID card or something like that.

You still don't have to take a pin to turn on the radio, but the ID card will be in the freq slot and can't come out on accident.

If someone is looking for the person who is on that freq, they have a pic of who they are looking for.

If someone forgets the ID, maybe have them put their cell number and home phone on the back.

Just some thoughts.

I would think you would want tighter freq control on the larger clubs to stop as many shoot downs as you can.
