I’ve been in the POS business for 25 years, and deal with the credit card side a lot.
A very large part of this is POS companies often have a relationship with the credit card processor (or are owned by a processor), and make a lot of money from the processing fees. The higher the fee on the processing account, the more they make.
So they convince the merchant (restaurant or store) that they can have a free system by passing the cost to the customer. Often times they are just waiving the monthly subscription fee, but some will also give the merchant free hardware as well (with a multi year contract).
Then they jack up the fees on the processing side: Since the merchant no longer has to pay the 2.5% - 3% fee that they were paying before, they allow the credit card / POS company to charge them 3% - 4%, and then pass it to the customer.



I’m 53 now, and could easily draw a map of the 2 houses that I lived in as a kid between 5 and 18 years old, along with most of the 10 or so houses I’ve lived in as an adult (a couple were very short term as a young adult, and I’m kind of vague on the exact layouts).
Before 3 years old I don’t remember much, a couple of vague things that could just be from pictures of me in those houses, rather than real memories. I kind of remember some of the house from 4 - 5 years old.
