> credit cards are giving you a revolving loan

I'm confused - is it not the issuing bank that gives you the loan, and the credit card company just provides the infrastructure?

Btw. having an overdraft limit of a few hundred Euros is quite typical for those liquidity issues. You don't need a credit card for that.

I used "value chain" euphemistically because you can get really complex on this and I wanted to spare the casual reader. I meant your credit card as an end-user product in your pocket and not meaning the card networks in isolation, but the value chain is roughly:

1. Merchant (bears little fraud risk but a lot of chargeback risk)

2. Payment Gateway (little direct risk but some liability risk)

3. Merchant Acquirer (more direct risk but mostly if merchants become insolvent)

4. Card Network (Visa/MC/AmEx - less risk but significant underlying costs managing a global technology that spans the financial system and needs to be distributed to almost every merchant of any scale in America)

5. Issuers (Banks + AmEx - most risk but get a big share of interchange fees)

I've surely missed something here that the very smart (and increasingly grumpy these days!) HN community will doubtlessly pile-on to correct, so I apologize in advance for errors or omissions... and I bow down if @patio11 swoops in to tell me about the complexity I've missed in either payments or Japanese economic/cultural conventions

Will also add that the benefit of credit is not overdraft but smoothing cash flow... if I'm living paycheck to paycheck and get paid every two weeks, I will incur essential expenses at the beginning of the fortnight that I can afford but lack cash in my account to pay now. I can't overdraft because I won't have the funds to deposit into that account for another two weeks. I'm getting a service that smooths my cashflow and there's a small premium added to reflect that. (Could you save up enough to avoid needing this? Is that a uniquely American way of living? I don't know! I'm making a descriptive claim not a normative one!)

		Sadly I’ve noticed that comments on this topic usually devolve into tribal comments about how ‘things are done in the EU’ which always seem to not be actually that representative of the 27 different countries of the EU, but of course must be better than the US.
