Why do I need to tap the customer's card when making a refund using Ingenico SoftPOS, and why can't I refund to a different card?

This requirement is implemented for security purposes. Ingenico SoftPOS (Tap to Pay) ensures that refunds are processed securely by linking the refund to the original card used for the transaction. This helps protect merchants from potential scams and ensures that all transactions are regulated and authorized, preventing unauthorized activity with the device.
