A microchip developed by a company based in Lamberhurst, in Kent, is being used to tag valuable instruments at the Royal College of Music in London.

Each chip is 1.4mm by 8mm and has a unique number which is registered into a database.

They have been used on string instruments at the Royal College, including one cello which is worth about £300,000.
