Major retailers like Dollar General, Five Below, Target, and Amazon are reversing their investments in self-checkout technologies due to increasing concerns over theft and inventory loss, commonly referred to as 'shrink.' Target has announced it will stop accepting personal checks due to their declining use, with checks now representing only a small fraction of noncash payments. This decision aligns with broader trends in the retail industry where digital payment methods are becoming more prevalent. Additionally, Walmart's stringent anti-shoplifting measures, which include locking certain items in glass cabinets, have been criticized by customers for causing inconvenience. These changes reflect the ongoing challenges and adaptations retailers face in balancing customer convenience with security and loss prevention.
