How A Vending Machine Works

After a user selects a product, the vending machine goes through the following process:

Product Selection: The user selects a product using the keypad or touchscreen and then enters the quantity to purchase.

Payment: The user can pay by card, scanning a code, or inserting coins.

Dispensing: Based on the selected product and payment status, the vending machine dispenses the product from the chute.

Receipt or Voucher: The vending machine issues a purchase receipt or voucher, and the user needs the voucher to retrieve the product.

Precautions
When using a vending machine, pay attention to the following points:

Avoid selecting damaged or expired products.

After payment is completed, follow the instructions to take your product and change.

Avoid selecting the same item multiple times to prevent unnecessary burden.
