Benutzte Schweizer Postfinance Card (Plus) funktionierte. Das maximum bei mir waren 3000 Bolivianos.
I used Mastercard and this worked fine!
The only ATM that seems to be reliable this side of Copacabana!
There was also no domestic charge for using my card here which is great!
Also right next to the bank so very safe (door locks from the inside).
FYI, Master card is not available. But Visa card is available.
