What does txn not allowed mean on card machine?
Excuse me, could you please clarify what "txn not allowed" means on a card machine? Is it an error message that indicates a specific problem with the transaction? Does it mean that the card is not authorized for the type of purchase being made? Or is it a sign that the machine itself is experiencing some sort of technical issue? Additionally, is there anything that the customer can do to resolve the issue or should they contact their bank or card issuer for further assistance? Thank you for your help in clarifying this matter.
