The Portronics Electropen 3 ­ comprising a wireless receiver and a stylus that uses a regular ball-point refill ­ is a combination gadget that’s built for the business traveller. It allows users to scribble notes and diagrams on a paper page, and converts it into a digital diagram on the fly.

All you have to do is install the Elec tropen 3 app on your Android smart phone, pair it via Bluetooth with the receiver, and then clip the latter to any A4 or A5 page.

The receiver, on detecting the stylus nearby , will scan whatever you write or draw and transmit it onto your app’s can vas. You can also use the app to create a video capture ­ along with audio notes ­ of whatever you draw on the paper.

The app also includes basic pen tools where you can choose ink colour, pen thickness and even draw simple shapes on the canvas. You can even annotate copy by importing images from the phone’s gallery. A screenshot tool saves your work as a JPEG file, which can be shared via e-mail, on social media or instant messengers.

The receiver and pen have built-in rechargeable batteries, which can give you more than a day’s worth of service. Additionally , this kit comes with a smart faux leather pen case, which you can carry with you in your shirt pocket.
