10. The system according to claim 6 , further comprising:
a prompting module configured to generate a prompt message to prompt the user to make payment in an alternative method.
11. A non-transitory computer-readable medium storing a program causing a computer to execute a process, the process comprising:
in response to a shopping cart being within a preset distance from a shelf, acquiring video data associated with the shopping cart;
determining, based on the video data, an article being placed into the shopping cart;
capturing an image of the article from the video data;
determining one or more product types associated with the shelf at a present period of time;
retrieving pre-stored images of the one or more product types;
identifying a product type of the article based on a two-stage matching procedure, comprising (1) performing a first matching procedure between the image of the article and the pre-stored images of the one or more product types associated with the shelf at the present period of time; and (2) in response to a nonmatch at the first matching procedure, performing a second matching procedure between the image of the article and pre-stored images of all product types;
