True Link, a San Francisco Y Combinator alum, is working
against such fraud with a pre-paid
credit card linked to an online dashboard family members configure to set
spending limits and block purchases at specific stores or merchant categories.
Here's how secured cards work, and why they make sense when your
credit is iffy: You put down a deposit with your bank, say $ 500, and that deposit acts as your
credit limit — meaning you
spend money
against the deposit, eliminating most of the risk for the bank.
