It's the only card I've ever had that can't be universally read. It's not embossed enough for the old systems (that attempt to get an imprint of the name and number) and it's apparently problematic in certain swipe readers. I think that 10% of the time I've needed to use a different card to complete a transaction. Hopefully you'll get a metal card with the same number as your plastic card --- as you'll probably find that the plastic one will come in handy!
