they can get bitcoin in paper form like what you get when using Bitcoin ATM.
pieces of paper with public and private address after that they can import the private key to any wallet "just show the private key to any scanner" and get the money.
Important point
you must have some knowledge and internet access to use bitcoin.
I believe thus was a good idea. This looks as of some kind if an offline bitcoin. Almost similar to bank cheques or check only with a private key. There just one thing in mind that is a bit of a problem, "How will the beggar get a hold of such a printed and offline form a bitcoin?" So the beggar should have just received it from another person . "Isn't this another problem for a beggar to understand what this bitcoin was all about?" Well given the situation that he only begs for alms then maybe he might not be able to understand it. These are the things that bothers me with it but I like the idea.
