Transponder - RFID

Radio-frequency identification (RFID)is an automatic identification method,relying on storing and remotely retrieving datausing devices called RFID tags ortransponders.

An RFID tag is an object that can be attached toor incorporated into a product, animal, or person forthe purpose of identification using radio waves.Chip-based RFID tags contain silicon chips andantennas. Passive tags require no internal powersource, whereas active tags require a power source.

Near Field Communication (NFC)

Near Field Communication or NFC, is a short-range high frequency wirelesscommunication technology which enables the exchange of data between devicesover about a 10 centimeter distance.The technology is a simple extension of theISO/IEC 14443 proximity-card standard (contactless card, RFID) that combines theinterface of a smartcard and a reader into a single device. An NFC device cancommunicate with both existing ISO/IEC 14443 smartcards and readers, as well as

with other NFC devices, and is thereby compatible with existing contactlessinfrastructure already in use for public transportation and payment. NFC is primarilyaimed at usage in mobile phones.

NFC technology is currently mainly aimed at being used with mobile phones. There arethree main use cases for NFC:

card emulation: the NFC device behaves like an existing contactless card reader mode: the NFC device is active and read a passive RFID tag, for example for

interactive advertising

P2P mode: two NFC devices are communicating together and exchanginginformation.

Near Field Communication (NFC)

Plenty of applications are possible, such as:

Mobile ticketing in public transport an extension of the existing contactless infrastructure.

Mobile payment the device acts as a debit/ credit payment card.

Smart poster the mobile phone is used to read RFID tags on outdoor billboards in order to getinfo on the move.

Bluetooth pairing in the future pairing of Bluetooth 2.1 devices with NFC support will be as easy

as bringing them close together and accepting the pairing. The process of activating Bluetooth onboth sides, searching, waiting, pairing and authorization will be replaced by a simple "touch" of themobile phones.

Other applications in the future could include:

Electronic ticketing airline tickets, concert/event tickets, and others

Electronic money

Travel cards

Identity documents

Mobile commerce

Electronic keys car keys, house/office keys, hotel room keys, etc.

NFC can be used to configure and initiate other wireless network connections such as Bluetooth,Wi-Fi orUltra-wideband
