How do I pay a fee with my debit card?

Hello, I'm curious about how I can go about paying a fee using my debit card. I understand that there are various platforms and methods available, but I'm not sure which one would be the most suitable for me. Could you please explain the process step-by-step, including any potential risks or limitations I should be aware of? Additionally, I'd like to know if there are any specific requirements or restrictions when it comes to using a debit card for fee payments, and whether there are any alternatives I should consider. Thank you in advance for your assistance.
