Alice should be able to pay using digital cash in any situation, for small purchases (like buying a hot-dog) as well as for bigger ones (e.g. buying a car). Digital cash should become well-known and accepted in a large commercial zone. Primarily a brand issue, this feature implies recognition of and trust in the issuer. Even with several digital cash providers displaying wide acceptability, Alice should be able to use her preferred unit in more than just a restricted local setting.
