NFC:

1. Stands for “Near Field communication”

2. Range of ~ 4 cm

3. Low speed

4. Used for sharing small files, such as authentication tokens for contactless payment

5. Due to low power & proximity, little interference occurs from radio waves

· Older Bluetooth signals used to only have a limit of 10 feet or so, newer signals can reach up to roughly 30 feet. However, the range will vary depending on obstacles (people, walls, etc).

There are five different versions of it. The first version was called 1.1, which was followed by 1.2, 2.0 plus EDR, 3.0 plus HB and version 4. They are backwards-compatible with Bluetooth devices.

·         The latest version lets a single device act as "master" and communicate with up to seven "slaves" at once.

·          In 2008, only 5% of mobile devices were Bluetooth-enabled. Compare that to today, when roughly 95% of mobile devices support it.

·         The protocol for Bluetooth allows it to be updated with ease.  These upgrades offer new features and are typically compatible with older forms.  Newer versions of the technology are currently being developed.

Near Field Communication (NFC) technology allows users to make secure transactions, exchange digital content, and connect electronic devices with a touch. NFC transmissions are short range (from a touch to a few centimetres) and require the devices to be in close proximity.

6cm range

# data[].attributes.body
basic NFC tags can usually hold only 48 bytes of information

# data[].attributes.body
NFC uses magnetic coupling to send and receive signals

NFC has a range of roughly 6CM

NFC range depends on the size of the antenna in the NFC enabled device.

There are two main types of NFC devices, passive and active.

They simply transmit data, unable to process it.

Bluetooth:

1. Shorter range than other systems

2. Direct communication to other devices

3. Uses low amounts of power

4. Mainly used for mobile devices

5. Communicates using Radio waves

6. Uses the same radio band as baby monitors, garage door openers & cordless phones

7. Named after King Harald Bluetooth of Denmark, the logo is the combination of the Runes for ‘H’ and ‘B’ in younger futhark
