Walmart already has EMV terminals. I don't go to Walmart very frequently, but last time I went there, I was unable to use my Amex card with the usual swipe; the terminal told me I had to insert the card into the chip reader. I haven't run across another retailer in the USA yet that even supports using the chip, must less requiring it when it's present (Many places have new terminals with chip readers but they are not enabled. See Target, Home Depot, etc.)
