INTRODUTION
NFC is a set of short-range wireless communication , Based on the Radio Frequency Identification (RFID), it uses magnetic field induction to enable communication between electronic devices
Typically requiring a distance of 20 cm or less. NFC operates at 13.56 MHz and at rates ranging from 106 Kbit/s to 848 Kbit/s.
How is NFC different from or related to other wireless?
NFC is a short-range wireless connectivity technology that enables simple and safe interactions between electronic devices, allowing consumers to perform contactless transactions, access digital content, and connect electronic devices with a single touch.
Bluetooth wireless technology was designed to replace cables between cell phones,
laptops, and other computing and communication devices within a 10-meter range.
Conclusion:
Like all new technologies, security concerns still remain.
NFC-enabled devices can change the way we make transactions ,
exchange information , and send and receive data.
In 2011, the big names in mobile technology plan to integrate NFC
with their new devices .Both Android and Blackberry
Wi-Fi technology was designed and optimized for Local Area Networks (LAN);
it provides an extension or replacement of wired networks for dozens of computing
devices within a +100-meter range.
ZigBee wireless technology is a standard enabling control and monitoring capabilities
for industrial and residential applications within a +100-meter range.
IrDA is a short range (< 1 meter), line-of-sight communication standard for exchange of data over infrared light. IrDA interfaces are frequently used in computers and
mobile phones.
