Besides the business license, you should also bring your ID card and letter of introduction. I don't know how to write it, so I put the seal of that unit on the white paper and take it to write.

However, you should pay attention to leave your phone number when registering. If you leave your phone number, you will call for information after you get the card. If the phone is disconnected, or the other party answers that there is no such unit, the card will be banned directly.

There is no purpose, depending on the business model. Cashiers do not issue receipts, but directly issue invoices or VAT invoices, so we must register the company name and related information in advance.
