How to Spot Ingenico Self-Checkout Skimmers
Summary: Ingenico issued a May 16, 2016 security bulletin describing how to identify skimmer overlays fitted to its iSC250 self-checkout card terminals, after a KrebsOnSecurity report on skimmers at some Walmart self-checkout lanes drew questions from retail readers. The bulletin says the overlay is over 6 inches wide and 7 inches tall against the iSC250's 5 9/16 by 6 1/2 inches, and that it blocks the keypad backlight and the green contactless LED, interferes with magnetic stripe reads, and blocks the stylus tray.
Why it matters: Each iSC250 overlay skimmer already costs a few hundred dollars before the electronics that store card data, and fraudsters have no guarantee of recovering a device once it is found - so employees and customers who know these five tells are the control that makes that up-front investment fail.
