The official currency of Cambodia is the Cambodian Riel, which is used by both natives and foreign tourists. In addition to the official currency, the US Dollar (USD) is also commonly accepted and utilized because of its convenience to users, particularly for bigger transactions. 100, 500, 1000, 2000, 5000, 10000, 15000, 20000, 50000, and 100,000 Riel banknotes are available. There are 1, 5, 10, 20, 50, and 100 dollar bills for the US dollar. 

Cambodian banks have set up an online banking system to make mobile and QR code payments easier. Banks including Chip Mong Bank, ACLEDA Bank, Canadia Bank, and ABA Bank are currently improving their online banking apps. Users have the option of sending money overseas for a slight additional fee or transferring money between bank accounts for free (local banks exclusively via Bakong). Nowadays, you may pay with your online bank account practically anywhere, especially at grocery stores, restaurants, retail centers, and more which is very convenient and easy.
