Enough competition? Collectively, those two control 90% of the credit/debit transaction marketshare as of Jan 2020. Almost every move and change is mirrored by the other -- they don't even try to hide the fact that they practically operate in unison. Almost all credit card companies have stipulations that merchants are not allowed to charge less for people paying cash -- forcing cash paying customers to pay the same price as those who cost the merchant a CC fee. This is basically a 3% tax we are all forced to pay on everything we buy.
