The story of Visa is one of the great untold stories of American and international business.
Why carry cash or checks if you can get a visa or mc? Lose a visa or mc? No problem if you exercise due diligence in reporting it lost/stolen (not the same with cash or checks unfortunately). Order something & it doesn't get delivered? No problem more often than not (with no attorney needed) when paid for with visa or mc, again as long as due diligence is exercised in reporting the problem (not the same with cash or checks unfortunately). The list of benefits associated with visa & mc "currency" over cash & checks goes on & on. Visa & mc are available today, everywhere.
Literally don't leave home without a visa or mc (the truth of that ad phrase is ridiculously deep).
It is a must read for anyone who works in this industry or has a card.
