Comment Magnetic strip? (Score 1) 212

Why ATM still relies on magnetic strip card...that the data (key) could be easily replicated?

We have smart card for years, NFC card for years...Couldn't the bank phase out all those magnetic card with NFC one?
I presume sniffing the NFC air traffic does not compromise the system, of course.

Eye-Fi is a real SD card, and appears to be a storage SD card to the camera. Instead of Wifi card using SD as interface.

Consider this is a USB Flash drive - but it can do two-way sync to the Wifi (Wifi configured separated, not with convention tools, and you cannot get network connection with that Wifi either). And this is not USB Wifi stick. Now s/USB/SD/g and you see the different.

I live in Hong Kong so maybe I could chime in. Hong Kong and the rest of the mainland China is running two system, having different jurisdiction and law.
Factories were moving to Guangdong province (mainland China), where is just 100 mile anyway, anyway regardless of the law because of the cheaper labor cost (around 5 to 10 times).

Plus, factories moved from Hong Kong to Guangdong is just accounted for a small percentage, compare to the whole mainland China. Perspective: Hong Kong population: 7 millions. China population: 12 billions.

Maybe mainland China have some similar environmental protection law, but mostly they could get away by bribing the officials.

Same for NFC and mag-strip. Access to audio maybe easier than NFC signal, but it's still "open" to user. Same for SSL...it's all in-band and accessible.
Last time I read a NFC related spec, a asymmetric encryption/PKI is employed.

If phone company run the signal in-band today with the signal signed with PKI, etc etc, it's just as secure as running it out-of-band. It's just we didn't have the technology to do that efficiently a few decades ago.
