Credit card network operators brag that accepting their network means customers will spend more. If spend increases even 1.6%, you are on net spending more.

CC acceptance decreases "friction." Some part of it is unlinking paying with the feeling of depleting resources when you pull cash out of your purse or wallet. Maybe running low on $20 bills and having to go to an ATM makes you decide to put one item back on the shelf. Or one's bank account is nearing bottom. In younger generations the opposite ironically can happen. They feel digital numbers fully but cash is spent more freely.
