Pardon me here if I have a different take here from grim experience. As no has considered the possibility of identity theft that plagues all honest merchants. And for that matter all honest consumers.
As credit card companies make money two ways. (1) By charging the merchant some 3% plus on every transaction that sticks to the credit card company, when the merchant would make more money accepting only cash. Lets ignore the risks of merchants accepting check for the moment or reward card that rely on fees above 3% for the moment. (2) The real giant money made by credit card companies is on the 18% interests charged to the intellectually weak who are allowed to borrow too much money on credit cards. As they finally find out they can never pay back the debt. As maybe our nation can simply say, fools and their money are soon parted. Especially when the fools have no choice to resort to bankruptcy in which case they have a clean credit rating, can get new credit cards like candy, and start the same cycle again.
As I submit only those who become victims of credit card fraud can really understand how corrosive the credit card system is.
As I amplified for credit, gradually built up my credit rating, and even got two credit cards I used very seldom. Then one fine day, a credit card identity thief got enough information, and in the space of a month, applied for a pile of new credit cards in my name, they sailed through given my credit rating, and at the same time the identity conveniently thief made themselves as co users on my account. And even more conveniently changed my billing address to somewhere else. It too me better than a month, to find out, what a thrill to find out I had so many credit cards I never applied for, and all maxed out in a matter of days. What a deal, what a deal, I ended up getting all the bills and the identity thief got all the goods.
But at least I could have some faith that the US credit system would work as I was foolishly thrilled my credit rating was thrashed. Meaning the identity theft could get no more credit in my name. But no no no, there are many companies who don't bother to pay credit rating agency fees, and assume if someone granted me credit before, they could safely do the same. As I begged US credit rating agencies not to allow me or anyone else to apply for credit in my name as I had the weekly thrill of discovering new maxed out credit cards in my name.
To make a long story short, it took me 3.5 years to clean up my credit rating, and when the identity was finally caught, no credit card companies lifted a finger to see the fraud was prosecuted to protect the integrity of the credit card system.
And instead the credit card companies paid up. Because if the credit card companies ever asked the merchant to check if the name and drivers license of the User of the credit card matched up with the name on the credit card. And then went on to the required step further to say if a merchant did not do that simple check, the credit card company would let the merchant eat the fraud.
But no no no, rather than having the first line defense against fraud, instead credit card companies always pay up, because if they don't, merchants will discover, credit cards are not always gooder than gold. And even worse, start questioning why they should be paying 3% plus on every transaction.
As a result, identity theft rolls merrily along. I hope it never happens to you, as almost nothing I can do can prevent from happening to me again, but there is nothing more disillusioning in calling the cops and finding out you would be better off in calling a hippie.
