In March 2021, the National Bank of Cambodia (NBC) enforced the Circular on E-KYC Guidance and Transaction Limit for Payment Service in Cambodia, clarifying procedures and information required for payment service institutions to identify customers and to set limits on the daily transaction amounts allowed for each type of customer. The Circular established the Bakong Payment System by the NBC, which is a centralized platform that allows customers to make bank transfers across banks and payment institutions. Based on the Circular, the size of daily transactions permitted depends on the platform, the personal information provided by the customer, and the stage of the payment service institution’s review of the customer’s information. In accordance with the different customer risk levels, customer identification procedures are determined by the four following transaction types: (i) Transactions between Bakong Accounts; (ii) Transactions between Bakong Accounts and Bank Accounts/E-Wallet Accounts; (iii) Transactions between E-Wallet Accounts and E-Wallet Accounts/Bank Accounts and; (iv) Transactions between Bank Accounts and Bank Accounts via Bakong (Backbone).
For transactions falling under items 1 – 3 above, customers are classified into three categories:
- Basic Customers: The transaction limit is KHR 2 million (approx. USD 500) per day;
- Partial KYC: The transaction limit is KHR 12 million (approx. USD 3,000) per day;
- Full KYC: The transaction limit is KHR 40 million (approx. USD 10,000) per day.
- For transactions falling under item 4, customers are considered as full KYC customers and the transaction limit is KHR 200 million (approx. USD 50,000) per day.
