Totally agree that we need un-named cards back. There are many examples including the ones already mentioned, but I’ll mention my personal anecdote.
My cousin is a hugely successful record producer and DJ. We’re talking tens of millions of sales and productions/writing credits for some of the biggest names in music over the last 25 years. He also has a very unique and “interesting” name. He is literally the only person in the world with his name. When I first got him onto our prepaid Beta and he started using it, one of his first reactions was that he liked that it did not have his name on it because people in stores have looked him up before.
I really hope we can offer the un-named cards again soon, or even the “Monzo Bank” ones, which is what I’ve been using myself for a while!
