Earlier quoted context omitted.
Here's why: two debit cards, one for receiving money, one for spending money. Automated payment from the 1st one to the 2nd one once a month with a fixed amount you expect to spend in a month. Nothing to pay off, you're spending your own money, can't be overcharged, can't go below zero, if someone leaks your spending card they can't touch the majority of your money, no scummy business practices. Never owned a credit…
>>one for receiving money, What do you mean debit card for receiving money? In what sense? >> Automated payment from the 1st one to the 2nd one Again, I have absolutely no idea what you mean by that. Payment from a debit card to a debit card? What?
Seems like a lot of work to do what CCs do automatically. I guess the upside is that crazy spending is impossible (well, if you make sure to forbid negative balances on the spending account) and it's impossible to accrue interest.
