# Binding products and instructions
The product ID is bound to the specific instruction. This instruction can be bound to a certain product.
Common usage scenarios are as follows:
## Vending machine
After the user places an order to purchase goods on the mini program, h5, web, or app, the system automatically activates the power switch, opens the door or gate, or controls the rotation of the motor to eject the goods.
## Unmanned hotels, chess and card rooms, dance studios, gyms, tea rooms, etc.
This need is combined with the daily pricing and period pricing of goods to provide users with a reservation function. According to the scheduled date and period, the user executes control instructions (such as opening the door, turning on the lights, closing the curtains, etc.)
After the reservation time is over, the system automatically triggers control instructions, such as automatically cutting off the power when the reservation time is up.
