In the last few months, near-field communication (NFC) smartphone cases have been going viral on social media. The specialty of these cases is that they allow users to display photos or graphics of their choice. NFC smartphone cases are considered to be very unique cases of their kind, where NFC is only a part, while the color e-ink display is the main technology of these cases. NFC smartphone cases are now available for many smartphones such as Samsung and Apple's flagship models. However, it can be difficult to find them for budget smartphones, as these cases are expensive and cost more than Rs 1,000.

What is an NFC case and how does it work?
An NFC case is a smartphone case that has a color e-ink display. This is the same technology used in e-book readers like Amazon Kindle, which enables users to show photos and digital art on the back of their smartphone.

When you attach an NFC case to a smartphone, it transmits data from the phone via NFC. NFC can transmit data just like Bluetooth and Wi-Fi but at a much slower speed. These cases only work with phones that support NFC.

Most NFC cases connect to the phone via an app that transmits the picture or graphic. Different types of NFC cases come with e-ink displays in different colors. Budget options have monochrome e-ink displays, while more expensive cases have three or four colors of e-ink displays that offer a more Live Photo-like quality.

Does it require a battery?
The biggest feature of NFC phone cases is that they do not require a battery. The NFC chip can work even without power and can get energy from the system itself. This does not affect your smartphone's battery.

Are there any disadvantages of NFC cases?
At the moment, there are no major disadvantages to NFC cases, except that you need to install an additional app on your phone to use them. If you want to customize your smartphone in a new way and show off your style, an NFC case can be a great choice.
