How do you write a letter to bank manager for handover ATM to my wife?

When writing a letter to the bank manager to hand over an ATM card to your wife, address the manager formally using their proper title and name. Clearly state the purpose of the letter in the opening paragraph, explaining that you are requesting the ATM card to be handed over to your wife. Provide your wife's full name and account details for verification purposes. Conclude the letter by expressing gratitude for their assistance and providing your contact information for any further communication. Be sure to sign the letter before sending it to the bank manager.
