Abstract
Techniques for weight checking for verification of ticket switching are disclosed herein. An example system includes: a weighing scale; cameras configured to capture images of items passing through a product scanning region and images of barcodes affixed to the items; a processor; and a memory storing instructions that cause the one or more processors to determine a first identification of an item based on the image of the barcode; determine a second identification of the item based on the image of the item; compare the first identification to the second identification to determine whether the two identifications match; based on determining that the two identifications do not match, generate a request for the user to place the item on the weighing scale; determine that the weight of the item does not match a first weight associated with the first identification of the item; and trigger one or more mitigation actions.
