I think it depends where in the world you live. Where I live most homeless people have bank accounts, and many even receive some kind of income - their income just isn’t enough to pay for housing. Also, homeless people can sometimes be homeless for other reasons such as family issues, or poor mental health. It’s a complex issue. So, I think QR codes for homeless might be the least of their worries. A lot of people who are living in deprivation are not thinking about long term goals, they’re thinking about survival today so a lot of their decisions and actions will be about what they need today. This makes it more difficult to overcome the challenges of being in deprivation. I was homeless for a short time when I was about 18 - I never begged though with street signs, I slept on different friends couches or floors at night. It was only for about 3 months, but every time I had money, I spent it on food. No long term thought processes were happening.
