To participate in PromptPay, users need to register by linking their existing bank accounts with their citizen ID or phone number through convenient channels such as mobile banking, internet banking, ATM machines, or branch services. Registration can be completed at the user's convenience and readiness.
Individuals who has bank accounts across different banks do not need to register PromptPay for each account; they can simply choose one account for receiving money via PromptPay (e.g., Mr. A). Alternatively, if individuals wish to use PromptPay with different accounts, they can link their citizen ID to the first account and their phone number to the second account (e.g., Mr. B and Mr. C). However, it is crucial to note that the same phone number cannot be linked to more than one account.
