The only retailer you mentioned that isn't in the Top 10 of NRF's TOP 100 RETAILERS CHART 2015 is Best Buy, and it came in at #11.
Aeropostale didn't even rank on the Top 100 list.
My thought is that the processors are giving the bigger retailers head-of-line privileges when it comes to certification. What's your thought on why they aren't taking EMV transactions if they already have the equipment in place?
Perhaps the retailer is unaware of the liability shift, or they don't feel the need to upgrade to EMV because the headache of having their customers use a new technology is a pain in the rear-end.
