Abstract:
The Erasable Barcode prevents the sale of products by invalidating the barcode. The invalidation can be based on shelf life, or improper temperature maintenance. The invalidation is also visible to humans so that the consumer knows if the exposure occurs after purchase. Activation brings liquid from the first reservoir in contact with the migration medium. The liquid progressively produces a change in color over time in the migration medium. When the liquid has crossed the migration medium, it will come in contact with the absorptive medium. The absorptive medium will then rapidly change color. The absorptive layer is the substrate for a machine readable barcode such that the color change renders the barcode unreadable
