National Transport Tokens are used to in lieu of, or in combination with, regular currency when using public transport.
In the United Kingdom, the tokens are usually purchased by the local authority or welfare organisations. They can be used on most public transport services. NTT's are currently minted in denominations equal to regular British coin currency, with £0.10 being the minimum denomination.
