Forum moderators here have been stating for years that it is a good idea to have multiple debit card designs for people with multiple accounts. And for years they have been stating that they are forwarding it "up the ladder". I think its time to find a different ladder because it has been years and not one thing has been done about it.
I just had the problem last week of using the wrong card because they look all look exactly alike. This is a very simple fix and something customers have been asking for for a very long time.
I have brought this issue up numerous times with phone representatives. Im tired of having to put stickers on my debit cards to tell them apart on our multiple accounts. I'm going to take care of the problem by moving my accounts to other institutions and droping all of the other services that I pay for as well.
