Thanks for the suggestions,

To explain my situation I'm looking to do a magic show once covid has died down. So I'll gather a crowd and then hopefully at the end I'll have a number of people coming up and throwing money in my hat, which takes just a second. now crowds are becoming cashless, having a large audience having to queue up as I slowly process donations manually would really slow things down, and even put people off.

So having a touchless card reader that charges them £3 a pop would be really handy so people can come up, tap and go. Also parents could give the card to their children to swipe for them.

It's just a shame we're loseing the simplicity of throwing money in a hat.
