Before payment, you must fill in the collection code of the property with the customer's phone number. Is this receipt code legal?

Personal payment code doesn't matter, because the payment code is mainly used when you need to collect money from others. Different from the payment code, the payment code will not automatically update the QR code, so some small businesses will post their payment codes in the store to collect money, but in the era of mobile payment, it is even more necessary to develop good payment habits.
