Picked up my new credit card today. It's one of those backup cards, that don't actually cost you anything unless you carry a balance (and this one apparently allows you to actually deposit money into its linked account, creating a debit balance above what the bank is willing to lend you). I've had one of these forever, but only remember actually using it once, after graduation, when I moved out of the student dorm and needed quick cash for the deposit on a rental apartment. Yeah; that would have been summer of 2005.
Here's an interesting observation. Since there is no actual cost for having the card in a desk drawer somewhere, I figured I might as well raise the credit limit, to the maximum of what they'll give me. The previous limit had been set somewhere around 2006 or 2007, and my income's grown a bit since. It used to just be a matter of asking for it - the bank teller would bring up my account history, see how much money was coming in, and the software would calculate the pre-approved max limit.
Not so any more. Despite being a fiscally very responsible person with most of my financial business at the same bank and no history of payment troubles at all, I could not reset the credit limit right then and there. Any change now has to go through an actual credit approval board.
Overall, this is a good thing. It's not like I actually needed credit, and a layer of sanity checks at Estonia's large consumer-facing banks is healthy for the country.
