Wal-Mart Confirms Chainwide Self-Checkout Glitch

When a picture of a Wal-Mart self-checkout screen showing the wrong total for a purchase made its way around the web last week, many assumed it had been altered or perhaps the screen had been captured the instant before an update. But Wal-Mart has now confirmed that a software update impacted almost all of the chain's self-checkout units for about two weeks, causing incorrect and confusing displays. The receipts and the amounts charged, however, were reportedly correct.
