Last week I noticed that my ATM access card for TD was cracking (right through the middle of the on card chip), and my wife told me I should go get a new one before this card stopped working (because it would most likely stop working at the most inopportune moment). This sounded like a good idea to me, so one night last week I managed to get to the TD branch near my house.
Mrs. C8j had told me that you didn’t actually have to go to a teller to get a card, you could simply drop by the desk at the front door and they would take care of you, and so I did, and I met a bubbly young lady who was very helpful. She had a look at my card and said yes now would be a good time to replace the card as it wasn’t going to last much longer. The next question she asked is sort of the crux of my point here: did I want to replace my existing card or simply take a new card with a new number?
The TD ATM card doesn’t have your name on it, so it can be quickly replaced if you wished, and then the young lady pointed out that if I wanted the same number, it would take 10 days to get a new card, however, to get a new card with a new number could be done right away. I decided I’d rather have a new card with a new number, since my old card was not going to last.
This meant I then had to change my on-line access information with the new card number (after the young lady had set up the new number as my new access card number), but it was pretty easy to do, and didn’t take very long.
The inadvertent security crossed my mind as I changed my on-line interface, as now that number is changed if anyone had stolen my banking info or “cloned” my card (as Mrs. C8j had in TD I Apologize ) . I wonder what TD might do if every 6 months or so I came in with a damaged card and asked for a new one? My guess is they might not care much, although their security division might notice after a while, but this looks like an interesting security measure. The number on my ATM access card is not needed for anything except for ATM transactions and Interac transactions, so changing it just means I have to change my on-line banking.
I believe I have stumbled across an interesting inadvertent security measure.
