A London-based startup has joined up with Mastercard Inc. to launch a payment card that allows users to retroactively choose a different credit or debit card for a purchase they have already made, in what they called “financial time travel”.
Starting Tuesday, Curve will offer customers the chance to “go back in time” and switch the card used for any given transaction for up to two weeks after the purchase, in what it said would be a world first.
The startup also said on Monday that it was planning to announce backing from two large international banks soon, but declined to provide more detailed information.
