Hello, first of all, congratulations to the landlord. I am an employee of McDonald's. I can use the points sent by mobile as long as they are within the validity period, and there is no limit to the number of them. If they expire, they will be invalid! You can't exchange the things in this kind of coupons, only the products specified in the coupons, and you can't exchange them for other foods, such as packaging, and you can exchange them all at once! If you exchange points, Mobile will send a multimedia message and a short message to your mobile phone! If you use it, just take the short message from your mobile phone. Tell the employee where to change the QR code, and he will understand what it means. Then he will take your short message and verify it on a verification machine at one end of the counter. The main content of that message is a string of numbers, which is very important. Without any number, you can't change it. Some customers will change it with that MMS, but the screen of the mobile phone is very bright and sticky, which affects the machine to read the QR code. Therefore, it is recommended to take that short message.

The landlord can take friends to eat, or forward the short message sent to you by mobile to your relatives and friends! Just take that message and you can spend it, not limited to restaurants!
