Bali has developed over the last 10 years and one of the good things for tourists is the number of ATMs located all around the island. You will find a range of ATMs belonging to local bank banks on most busy streets and also inside convenience stores like Circle K. These machines accept cards from all over the world and I can use my Washington Mutual bank card from Oregon.
Many systems are covered, Plus, Maestro, Cirrus etc, and there are a few things to point out regarding the machines. They dispense cash in 50,000rp & 100,000rp denominations. It was usually say on the machine, which one you will get. The amount you can withdraw each time varies. BCA machines allow 2.5m rp and a maximum of 5m rp per day. If you accidentally mis-type your PIN 3 times, the system will bar entry to card for 24 hours, but your card will be returned to you immediately.
On occasion during power outages the card will stay inside the machine and resume its process from the last point, when the power is turned back on. If you have already entered your PIN it will be possible to withdraw cash, meaning if someone else gets hold of the card they have access to your bank account.
Machines all ask whether you want instructions in English or Bahasa so language is not a problem. Most of the booths are AC too.
