I found out the hard way (at the ATM (Automated Teller Machine)) that I had in fact lost my check card. No amount of scouring through my wallet or the various locations I keep my wallet at home brought to light the hallowed card.
I had last used the card on the 13^th at an ATM (in fact, the same one I was at when I found my card missing), which goes to show you just how often I actually use the card. Spring [1] and I went back to the video store we rented videos from the other day, thinking that it may have fallen out there.
No luck.
Upon getting home, I called my bank and had the current card cancelled. I was worried since with a check card you are liable for more money if it is abused than with a proper credit card. The good news is that there wasn't much money in the account to abuse (the bad news being—there isn't much money in the account to use). Fortunately for me though, the last transaction on the card was the ATM from the 13^th so I most likely left it in the machine.
I ordered a new one but it'll take something like two weeks to arrive (given the current holiday season and the recent Anthrax scares). Sigh.
