There's little need for your bank to double-check with you for credit cards, IMO. In fact, in the few instances where my bank has checked with me, it's been a pain in the ass. (Travelling or otherwise making unusual purchases.)
If you don't agree to pay a merchant, you dispute the charge after the fact and the onus is on the merchant to prove that you agreed to that amount and that they delivered the product/service satisfactorily, etc.
In 2 decades, I've probably disputed 5 or 6 charges. In every case, it took less than 15 total minutes of time, and averaged under 10. So, in 2 decades, I've spent an hour dealing with credit card issues that smartphones might solve. And believe me, I'm not shy about using the plastic, averaging $30K+ per year in purchases on the card to get the 1% cash back.
I'm just not sure I care about better security for my CC information, and I'm sure I'm not alone...
