Cleaned up my bank accounts in the Channel Islands and opened a new account with Rothschild & Co in Guernsey a while back - money market/cash management is their bread and butter and they are one of the few private banks that would do it as a standalone service instead of only for wealth management clients.
Since I posted an Apple Pay screenshot containing the cards - I thought I come back and post the actual cards as well especially since they had actually changed the design since I first opened the account.
I quite love the new design. The debit card is blue on a white background and the charge card is dark blue. The charge card also arrived in a very fintech-esque package with a pull tab.
They also have an app to manage the cards - the same UI design has been used by a few smaller banks. I suspect they all use the same underlying technology.
