alt Hacker NewsMy wife found out her new card was Discover debit card right before her trip to France. Her bank sent her a new card unrequested. In an abundance of caution she activated the new card which automatically cancelled her debit Mastercard. Then when she landed in CDG found the new card didn't work anywhere.
This is what these peeps advocating for an "EU-based payment system" don't get, as they typically don't travel worldwide. VISA + Master just work. Have a debit plus credit for one each. (And no, Google / Apple pay won't do it, everyone who calls themselves a "hacker" should know that you too often can't even pay for transport using a rooted phone).
