I've seen a panhandler (in the US) flying a sign sporting a GoFundMe campaign URL.

I could see phone-to-phone contactless payment becoming commonplace in the same scenario.

Also QR codes in china: http://en.people.cn/n3/2017/0418/c90000-9204536.html

Here in Las Vegas, beggars already ask if you can VENMO them a dollar.

They usually have VENMO, PAYPAL, and the CASH app.

I even met a beggar once who had a stripe terminal and could swipe your card.

Edit: Ok, actually the last one is a joke. But not the first 3.

Not to mention pickpockets https://www.nytimes.com/2014/07/20/nyregion/the-pickpockets-...

Sweden is effectively the most cash free place on the map, and there is no shortage of beggars. Not really sure how this works.

Interesting thought experiment. If beggars accepted NFC payments I bet they'd make a lot more money.
