Two University of Arkansas professors have found that placing imperceptible barcodes on products may prevent injuries among cashiers and lead to more retail efficiency. Imperceptible barcodes are not visible to the human eye, but are placed all over the packaging so a product is scannable from any side. The research is published in the International Journal of Industrial Ergonomics.
