Tactile markings for blind and partially sighted people feature on the Bank of England’s new £20 note that are different from the existing £5 and £10 polymer notes.

The new note went into circulation on February 20 and includes three separate clusters of dots along the short edge to differentiate it from the £10 note, which has two clusters of dots.

It is purple in colour and larger in size than the smaller denominations, with a clear '20' marked on a white background.

The Royal National Institute of Blind People (RNIB) has been working with the Bank of England to make money accessible for people with sight loss and involved 50 blind and partially sighted people during testing of the note’s development.

David Clarke, director of services at the RNIB, said: ‘Handling cash can often be a challenge if you're blind or partially sighted, because it can be difficult to tell the difference between the different notes and coins. We hope the creation of these notes will help enable people with sight loss to use money more easily and with confidence. By incorporating tactile features on money, we are closer to creating a more inclusive society. It’s the small changes that can make a big difference to independent living.’
