Samsung defines Near-field Communication or NFC as a standard defined by the NFC Forum, a global consortium of hardware, software/application, credit card companies, banking, network-providers, and others who are interested in the advancement and standardization of this promising technology. http://developer.samsung.com/android/technical-docs/Near-Field-Communications-in-Android
They also define NFC as a short range wireless technology that allows enabled devices to share information in close proximity. It’s similar to Bluetooth, but instead of programming devices to work together, all you need to establish a connection is to hold the devices close to each other or touch them together. Once within range (usually 4 cm or less) NFC allows the transfer of data or power in just seconds. http://www.samsung.com/us/article/near-field-communication-a-simple-exchange-of-information
It is a set of short-range wireless technologies, typically requiring a distance of 4cm or less.
YES, THEY CAN SCAN YOU FROM A DISTANCE!
Compared to other wireless technologies such as Bluetooth or WiFi, NFC provides much lower bandwidth and range, but enables low-cost, un- powered targets and does not require discovery or pairing. Interactions can be initiated with just a tap. TIME TO SHIELD YOUR WALLET! I’m told a lead wallet for helps named ALUMA WALLET: http://www.officedepot.com/a/products/278637/Aluma-Wallet-Black/
