I spent a month in Cambodia and had a great time. Payments are mostly done by QR code now, then cash, then card.
For cash, I ordered new $100USD notes from one of the banks in Hong Kong. I was told the businesses check bills carefully, so they need to be crisp and never folded. After a few days I found out USD still works almost everywhere, but the government is encouraging more use of the Riel.
I found a few good ways to exchange money:
- I first changed $50 at the hotel. The rate was fine but slightly worse than elsewhere.
- ABA Bank turned out to be the best option as they didn't charge fees and their rates were almost the same as online rates. They were also quite happy to break some USD into smaller USD notes without fees as well. There are ABA branches all over Phnom Penh and Siem Reap.
- A few of my friends tried the street exchangers and got a slightly better rate than ABA, though the difference was small.
Personally I thought the variance in exchange rates was negligible and better to do it in a bank.
Riel notes are accepted even if they’re worn out, but places are quite picky with the USD condition. We found that in the villages people pay mostly in Riel, though they take small USD bills too, but don’t expect change in USD. In Siem Reap and Phnom Penh some shops were quite happy to give USD back in change.
QR payments are everywhere now. The government rolled out an app for tourists called Bakong. It links your card for local payments, though I couldn’t get mine working. Locals use their own version of the app, and I think the QR code works for both apps.
I’ll try setting it up again next trip since it would make things easier than carrying so much change.
Basically 1 beer = $1USD, buying a slab = 50% ROI. Simply lovely.
