Hello, card friend!
The situation you described in your question is the channel currently adopted by many people for recharge-related businesses. Whether you need to pay for recharging water, electricity, gas, etc. through this channel depends on whether your credit card issuer supports these services, or whether it cooperates with the issuer of the self-service payment machine. If it is supported (with cooperation), then you will not be charged any handling fees and interest; if it is not supported, then your payment behavior may be treated as a cash withdrawal, and handling fees will be charged according to the payment amount, and daily interest will be paid ( Five ten thousandths).
If you are not sure, you can directly consult the issuing bank of your credit card.
