Let's talk money. Apple, the tech giant, the iPhone maker, this week launched … a credit card. That's right, Apple Card, linked to Apple Pay. Apple's pitch with the card? It starts with cash and goes deep with security and design. This week we're going to take a closer look at the card and the app … which I have seen up close. And we're going to compare it to the deals and features you can get elsewhere. Is it really a good deal?  With me this week: Sara Rathner from NerdWallet – a site that studies these kinds of things – and joining us a bit later, CNBC's Dierdre Bosa.
