Oreo
The problem is that few people would be happy about street card transactions.
Is the charity worker a bonefide person? It would be easy to con people into tapping their card but who knows where that money would go or if the card machine had been rigged to get bank details.
In my experience people were happy to put a bit of cash in an envelope and we were all allocated a few local streets to collect from.
Yes - you're right.
I'm thinking though of the infrastructure called "RtP" - 'Request to Pay' which is essentially a digital Giro invoice.
You don't use your card, but you do need your smartphone for this kind of transaction, so the risk is similar.
People standing outside supermarkets give more confidence that the charity is genuine - but fraudsters and scammers are so bold these days that you can't really be sure about that...
I had a charity actually knock on my door. They were genuine enough, but I was in the middle of evening dinner so not best pleased.
Also, they would not allow me time to consider - I told them I could - and would - access their well-known website and probably make a suitable commitment. However, they were not happy about that because they were "chuggers" who, I believe, are paid some sort of commission. So, if I signed up online, they'd not benefit. Tough, I closed the door.
So Oreo, I don't know what the answer is, but it's certainly not accosting people on the street... nor knocking on the door at 8 in the evening (even tho' I understand why they choose this time) - and definitely not hurrying people to sign-up there and then for the sake of a commission.
Individuals and gangs rob people on the street - and there's very little police presence to deter them either because so many cuts were made to the force - IIRC, a police 'chief' did say at the time that this would lead to them being unable to 'police' satisfactorily. But, that's another discussion.
There must be a way to donate to charity in these straitened times, but blowed if I know what it is...
