System and method for preventing cashier and customer fraud at retail checkout

A detection system, comprising:

• one or more item identifier acquisition devices to acquire identifiers of items to be transacted;
• one or more cameras or imagers to acquire images of the items to be transacted;
• an object recognition component to perform visual recognition of the acquired items through comparison of the acquired images of the items with a database of item information and obtain identifiers of one or more items represented in the database of item information that correspond to an acquired image according to a correspondence criterion;
• a comparison component to compare a set of identifiers acquired through the one or more item identifier acquisition devices with a set of identifiers obtained through the object recognition component to detect, identifier by identifier or between the sets as a whole:
• i) match or mismatch between the identifiers acquired through the one or more item identifier acquisition devices and the identifiers obtained through the object recognition component, and
• ii) absence of identifiers acquired through the one or more item identifier acquisition devices when identifiers obtained through the object recognition component are present;
• and
• an alerting component to provide an alert in case of discrepancies between the set of identifiers acquired through the one or more item identifier acquisition devices and the set of identifiers obtained through the object recognition component.
