I was thinking of ways to improve security for debit card purchases and I came up with something like this
- 1 empty back account
- 1 debit card tied to your empty bank account
- 1 main account with your money
When purchase needs to be made you instantly move money from your main account to the empty account with only the amount of money that needs to be used for the purchase. The money that is used is only on your debit card for a short period of time and this prevents your card from being used willy nilly if it gets stolen either in real life or online. Does it makes sense? Is there a system already like this?
I do this all the time. They're just linked accounts with the same institution. The second account I have was a high interest savings account, but these days it's an offset against my mortgage. My debit card usually never has more than $100 in it and it takes seconds to move money across if I need it.
