DAE memorize their debit card numbers and information so they never have to pull it out for online purchases

Doesn’t seem that weird to me and I feel like other people do it, but I’ve had people comment on it like it’s weird. I regularly buy from a website that doesn’t save card information and memorized it pretty quickly, recently got a new card and after a few purchases ive pretty much memorized that one too. IDK I think it’s pretty convenient having it memorized like that lol, even scanning is tedious cuz you still gotta grab your wallet and shit, unless you have it memorized like your first and last name of course
