Nearfield Communication

1           Introduction

Radius Communication is one of the leading Internet Service Provider (ISP) in the country with its point of presence in 3 major cities. With wireless Internet Service, Radius customers has been reaping the benefits of roaming Internet in the major cities of the nation. Beside ISP, Radius provides other various services like Internet Phone (IP Telephone), Web Solutions, Software Development. Radius is also authorized distributer of Mikrotik devices for Nepal. With unmatched Quality of Service (QoS), fanatical support, Radius has been recognized as one of the leading IT Company in the country.

This report describes the significant use of Near Field Communication (NFC), its benefits to the company along with staffs and challenges faced while implementing the system and its future plan.

NFC is a standards-based, short-range wireless connectivity technology that enables simple and intuitive two-way interactions between electronic devices. With NFC technology, consumers can perform contactless transactions, access digital content and connect NFC-enabled devices with a single touch. NFC simplifies setup of some longer-range wireless technologies, such as Bluetooth and Wi-Fi. It is also compatible with the global contactless standards (ISO 14443 and/or ISO 18092), which means transport agencies that have already deployed contactless programs enjoy a built-in advantage, as their equipment may readily interact with NFC enabled mobile devices and provide richer services. Communication occurs when two NFC-compatible devices are brought within about four centimetres of each other. By design, NFC requires close proximity and it offers instant connectivity, which provides an intuitive consumer experience that can be readily applied to the transit environment (NFC Forum, 2011). NFC operate at 13.56MHz with data transmission rates up to 424kbit/s.

1.1         How it works

The principle mechanism of NFC communication between two devices is the same as other wireless communication technique, there is both a master of the conversation and a slave. The master is called the emitter, or interrogator (reader/writer) and the slave is a tag or card.

To function, the interrogator sends out a signal to the tag. If the devices are close enough to each other, the tag becomes powered by the interrogator’s signal. This signal powers the tag, allowing the tag to be small in size and function without any battery or power source of its own.  The data is stored in NDEF (NFC Data Exchange Format) and is stored in the tag’s EEPROM memory and its structure is defined by the NFC Forum for interoperability (Proehl, 2013).
