Been seeing a few of these as of late, those weird squares that peeps scan with the cell phones.  Thieves remake them and stick them over existing ones and rob the digital money people now.

Even Home Depot is removing self checkouts as they can scan and print their own tag and stick it onto the merchandise.  I find this quite amusing.
