"Electronic cash registers would probably be developed rapidly, not only to show instantaneously the equivalent of any price in any currency desired, but also to be connected through the computer with banks so that firms would immediately be credited with the equivalent in the currency in which they kept their accounts." — F.

The future of checkout is pure currency competition. As a currency issuer, what should matter is not how many people pay with your currency, but how many payments ultimately settle in it.
