PenFriend helps the blind read

Boffins have come up with a new device that will assist blind people read audio labels on everyday objects, where it is aptly known as the PenFriend. How does it work? Well, the PenFriend relies on minute barcodes that when scanned by a digital pen, will kick off MP3 files recorded on the unit. Costing less than £60, it was developed by a UK firm alongside the Royal National Institute of Blind People (RNIB). Meant to be used to label foods, medication, clothing, personal documentation and film and music collections. No idea on whether the final product will be affordable enough for the blind all over the world, and not only those who are residing in developed countries.
