Some might suggest there is a purely physical reason why the iPhone 5 does not support near field communications.
The iPhone 5’s all-aluminum-and-glass body would block information from being transmitted to a terminal, according to Will Strauss, an analyst of Forward Concepts, a research firm that follows digital signal processing and chips.
In other words, iPhone 5 is physically incapable of supporting near field communications for reasons related to the design of the case. “NFC employs lower-frequency operation than cellular, requiring a longer antenna,” says Strauss.
A metal back shields any radio waves from reaching a nearby data terminal. Only plastic, Kevlar or something similar allows the radio connection for NFC.
