My friend has 3 bank accounts. Sometimes he transfers money from one or the other, and I frequently transfer money back to him. He normally prefers I transfer to the same account he sends from.
Unfortunately, on the transfer received page, I can only see his name, but no details about his account number. So when I have to transfer back, I have to ask him for his account number because all his three accounts have his same name so I can only distinguish between them from his account number.
