What is on a banknote to help blind and partially sighted people identify the different denominations?
Each denomination is a different size; the greater the value the larger the note. So a £10 is larger than a £5 note and so on. There is a densely coloured shape on the front of the note that is unique to each denomination – a turquoise circle on the £5, an orange diamond on the £10, a red triangle on the £50 – and the £5, and £10 notes have large denomination numerals on the front of the note. The £20 note does not require a separate recognition symbol because the denomination numeral is prominently displayed in the clear white area.
