French start-up Prynt recently presented its smartphone case, which includes a built-in printer.

The printer is in turn connected to the smartphone via Bluetooth and can produce a photo in about 50 seconds.

The developers say their case will soon be able to print pictures in just 30 seconds, a news website reported.

"At the moment, only one sheet of paper can fit in the case. However, this will soon be increased to up to 30 pieces," Clement Perrot, CEO of Prynt, was quoted as saying.

Prynt has been working on the new case since January this year and is planning to launch the smartphone case at the beginning of 2015.

The case was developed for four-inch screen smartphones, but the company plans to make models for larger devices  such as the iPhone 6 Plus and the Samsung Galaxy Note in the future.

It is priced USD 99 (approximately Rs 6,000). Moreover, if you take a snap using the Prynt app, it will record a video of the moment before and after you click the photograph.

The app will virtually turn your photo into a video that you can view.
