Having a card costs money. And if you are really low on money, that fee really bites.

Here in The US, the paper says "for all debts public and private" so its assumed people have to take it.
However, i have had apartments where the rent had to be by check.

And i have more and more problems paying monthly bills in cash.
The power company closed its offices, and now you have to go to Wallymart to pay.

Also, my cell phone provider accepts cash, but charges $5 for that.

Credit Cards should be illegal.
There is so much fraud in CCs that any normal person would scrap the whole system.
However, it is a way to create money out of thin air, AND track everyone's spending, so they just eat that huge fraud and never make a peep about it.
