I heard from an American friend that they don't even have chip and pin in the US, they still swipe and sign. Nor do they have mobile banking apps etc. Still use cheques
By the sounds of it the US infrastructure needs a lot of work before it's ready for this
Only one bank in the US currently issues chip and PIN cards to new customers (UNFCU). USAA used to issue them, but switched to chip and signature (though they still say chip and PIN on their website). Diner's Club US (which is a Mastercard, unrelated to Diner's Club everywhere else which is Discover in the US) is chip and PIN, but they no longer take new customers.
Most US banks are chip and signature - insert chip, sign receipt. VERY few shops, however, have chip support. Basically, most Walmarts, some smaller shops using First Data or Chase as their merchant bank, and it sounds like - very recently - some Home Depots.
There are, oddly, a ton of shops with chip readers (to name and shame a few - Target, Barnes and Noble, Lowes, Staples, Wet Seal, Sears, Ulta, Smith's, Aeropostale, etc) but which have them set to swipe-only mode (EMV chip support disabled/not set up).
Now, as for mobile banking apps - of course we do. Doesn't mean cheques aren't still used - even in the UK, cheques are still used - the deadline on eliminating cheque processing was delayed due to complaints from the few, mostly elderly, who still use them. The difference is that, in the US, I still write the occasional cheque - some people insist on being paid by cheque. I also get paid by cheque QUITE often. It's bizarre. But there definitely are alternatives.
