Duplicate cards still have different card numbers and chips though, so I think unless you could put the chip back in a card and use normally this method carries quite a few risks. Potentially in the US where chip+pin is rare this is not a risk!Thanks anyway, fun to see
Curious! In theory a card could be activated for remote payments again by the bank, hence probably this is the method thepaymentring uses, but if the bank didnt approve of this I can imagine them being difficult about doing so!!!In the UK at least, every card has a different number, even if you get an e-card on your phone or a spare partner-card. Despite this I love the DIY nature of this project and outcome, just think not possible in the UK (or Europe probably) sadly.
