NFC Technology May Change Your Daily Life
Near Field Communication, is a short range wireless RFID technology that makes use of interacting electromagnetic radio fields instead of the typical direct radio transmissions used by technologies such as Bluetooth?
To connect devices, Distance should maintain 10 cm max. NFC tags are ten times cheaper than Bluetooth enabled tags. Along with rapid data exchange for higher volume it also maintains High level of security. NFC can also work when one of the devices is not powered by a battery. Two mobile devices exchange photos or files using NFC and save their Internet bills as well as the long procedure to access each other. NFC Technology allows users to seamlessly share content between digital devices, pay bills wirelessly or even use their cellphone as an electronic traveling ticket on existing contactless infrastructure.
NFC-enabled device can work in following modes such as P2P (Peer-to-Peer) communication, card emulation and NFC readers or writers. Technically, NFC requires an initiator and a target to exchange the data. When an active device powered a passive device or card/chip using its electromagnetic field, it becomes the passive mode. Whereas, two active devices actively exchanges data with each other using near field protocol (NFC), that becomes the passive mode.
When it comes to compare among active & passive mode than oblivious, passive mode is more useful for the App developer who produce solution effective & more potential while developing mobile app by using NFC technology. However, payments and passport like functions are passive by nature, but highly useful and the most applicable to the present moment.For Authentication Process and data storage of critical Info NFC uses tags and it can be observed
LIKEWISE QR Code and barcode, NFC tags used in authentication as well as small data storage for critical info. Therefore, passport authorities are on the way to create mobile apps that let its authenticated users pass through ports without physical boarding pass just using their mobile devices with such apps.
In short, NFC is useful for mobile app developers working on the mobile app development for Smart e-transactions, smart ticketing, Smart keys, Smart Gov. or public services, parking pay, Traffic alerts, Aids in retail shopping by NFC tags on products, Beaming files.
