Doesn’t it sound like magic? When you pick your phone & Move it over a barcode, the payment is processed! This was something unimaginable till a couple of years back. This thought makes me feel so proud of technology’s rapid evolution! Let me take you through the magic called NFC Tag.
What is an NFC tag?
NFC is a cutting-edge mobile payment technology that helps in extracting data from barcodes using an NFC-enabled smartphone. This service is compatible with iOS and Android smartphones and a tag reader at the store where you may scan your barcode to pay. Contactless payments rely primarily on NFC. It is a wireless radio communications standard similar to Bluetooth and Wi-Fi. Retailers and package delivery companies, in particular, use RFID as a tool for tracking inventory, suppliers, and shipments. You could also have an RFID-enabled ID badge that you tap when you arrive at work.
Many of us use this technology already but never had a chance to know what it is and how it works! No worries, we are walking you down through some interesting information about this omnipresent technology.
What is NFC?
Near-field communication is a collection of communication protocols that allows two electronic devices to communicate across a distance of 4 cm or less. NFC provides a low-speed connection via a simple setup to launch more sophisticated wireless connections.
What is an NFC tag reader?
Have you ever seen the “no supported app for this NFC tag” message? NFC tag reader is an NFC device that operates in NFC reader or writer mode, allowing it to read the information contained on the chip. The Android system (or, more precisely, the NFC system service) displays the warning “NFC tag type not supported” before and instead of delivering the tag to your app. It implies that the NFC system service filters MIFARE Classic titles and never alerts any app.
iPhone NFC tags enable full access to NFC Tag functionalities with iOS 13. iPhone apps may now write information such as URLs and text using this new functionality. iPhones also have native tag access, allowing them to utilize the functionality offered on various NFC chips.
What is the NFC chip?
A Near-Field Communication chip is a silicon component of an Integrated Circuit (IC). Used in various ways depending on the application. When attached to a suitable antenna, an NFC chip permits short-range wireless communication between two devices. It ensures an extra degree of security as the devices in proximity to each other may interact via NFC.
NFC technology, for example, can enable contactless communication between:
- A credit card and a payment terminal.
- Two electrical gadgets.
- A smartphone as well as a consumer product.
NFC enables wireless communication through the chip installed in each system’s component. A few examples are:
- Financial card
- Payment terminal
- Passport to record biometric data.
These are to name a few!
