Post cards not working

My postcard (pre mastercard, but in post card accepting places) was declined in two different places today, when I got it out at a third to try the cashier told me postcards have not been working since yesterday.

Since then fiance was told at another place that they were not working.

I checked my efinance account and there were no messages.

Does anyone know what is going on?

Should be solved by now. No idea what happened.

Saw a message on the SBB app yesterday that they were not accepting Post Finance cards.

I’m surprised it was not on the new last night.

Migros today had a sign they are not accepting the "new" post cards,

Huh, I only have an old one and it is not working.

I wonder what happened

Wife had problems too on Thursday with the new mastercard one =/. We were a bit surprised about it.

It was on our local news site, it said things were partially restored but others were still not functional. I didn’t really pay much attention to the details as we don’t have any post finance accounts.
