Final answer:
A bank transfer request or a wire transfer instruction is a document that instructs a banker to transfer money from one account to another.
Step-by-step explanation:
A document that instructs a banker to transfer money from one account to another is called a bank transfer request or a wire transfer instruction. It is usually initiated by the account holder and can be done through various channels such as online banking, telephone banking, or by visiting a bank branch.
To complete a bank transfer request, the account holder needs to provide the necessary details such as the recipient's account number, bank name, and the amount to be transferred. The bank then processes the request and transfers the specified amount from the account holder's account to the recipient's account.
Bank transfer requests are commonly used for various purposes including transferring funds between personal accounts, making payments to suppliers or service providers, or sending money to family and friends.
