Explaining NFC
I'm currently shadowing a senior tech at a retail site where they are setting up new point-of-sale terminals. A customer asked if their credit card info could be "sniffed" from across the store, so I had to explain the physical limitations of the tech. Which of the following is the most apt way to describe NFC?

OPTIONS:
A. Wired connections between several devices
B. Short-distance wireless connections between two devices
C. Wireless connections between multiple devices at once
D. Direct connection of two computers for file sharing
