Just about a month ago I got a emv chipped card from my bank. The grocery stores and a few other shops near me have that same type slot reader under the keypad you mentioned. I've been sticking my card in all of them when it prompts for an insert/swipe but I don't know if they're just not enabled around here or what because it never works and I always have to fall back to the mag strip.
The thing I don't like about it, is on the signature block on the back of the card I just write check id, then I put clear tape over the sig block and the cvv so it doesn't wear off (I've worn off the cvv #'s before...). Anyway, so my old card had a picture of me on the front of it. The new one doesn't. So now if someone actually does bother to read where it says check ID, instead of just me saying look at the picture, I have to pull id as well (which is either an RFID Drivers license, or an RFID enabled passport card). So for now, I kind of miss my old photoid card, vs my emv chipped card that doesn't work. I already had to buy a faraday cage wallet because of my drivers license & passport card (I'm paranoid about the rfid stuff), and then another rf blocking pouch for my regular full size passport.
