How long until the designers rethink the design and make it as thin/robust as credit cards. I think there are already some adopters of keyboards with a credit card chip reader, though not sure how mainstream popularity of it would be jump started.

Lots of keyboards with smart card readers already, for customers like the US DoD. They're not pretty though. Don't expect to see one on display at the Apple Store.

I see cheap ones on sale for 20 bucks or so. Cheaper than an NFC reader. Programmable "Java cards" are affordable.
