Hi,
One day the idea of using a plastic card with a magnetic stripe may seem
antiquated. Cell phones may be better for identification/authorization
purposes. Bank transactions will still occur. To be robust, the less
concrete and more essential the use cases are, the better. The ATM card is a
specific detail describing how the business transaction is to be
implemented.
Larry Constantine specifically mentions the ATM use case when he
distinguishes between concrete and essential use cases BTW.
