Earlier quoted context omitted.
The benefit of credit cards is no one can literally drain your bank account via fraudulent access to a payment card directly tied to your bank (i.e. debit card in US nomenclature). This is a clear benefit regardless of location. Courts are slow and not scalable, and you don't want to be in a scenario where your bank has been drained right before you need to make important payments.
Perhaps. Adding... The benefit of credit cards is...credit, and the ability of the card to abstract the idea of spending money away from the consumer. Few things exemplify "out of sight, out of mind" better than credit cards. The model is amazingly profitable as well. Like printing money, literally.
In other words, you'd go to some electronics store and by a $2000 TV and they'd ask "how many payments". You'd say 10 and you'd end up paying $200 a month. I don't know the origin of why they did it that way. To be clear, this was bank credit cards, not store cards. I imagined it was something to do with the commitment and knowing you couldn't just pay off some minimum. Purchases under a certain amount and/or by store you were not allowed to divide up.
I've had Japanese friends come to America and want to buy something for $500 and ask if they can have ask for 4 payments and have to explain that system doesn't exist here. If you want to make 4 payments you make 4 payments.
I've never looked into if the bank is giving all the money to the merchant and then charging the customer per month or if they're sending to the merchant per month. Nor did I ever look into interest fees. I just know it is (was?) common.
