An acquaintance sent me a message saying how much money was left in my bank card.

Does the subject want to ask, "An acquaintance sent me a text message saying how much money is left in my bank card to reply?" Bank cards have no money and have been consumed in daily life.

1. According to Sohu News Network, the bank card had no money and was lent to colleagues and friends.

Thank you for your concern. There is no deposit in the bank card and it has been spent in daily life.
