Why isn't the price on the bar-codes?

Prices are typically not included on barcodes to ensure that retailers can easily update pricing without needing to reprint barcodes. This allows for dynamic pricing strategies, promotions, and discounts to be applied at the point of sale without altering the product's packaging. Additionally, barcodes are designed to contain product identifiers, which are linked to a database that holds pricing and inventory information. This system helps streamline inventory management and sales processes.
