As i understand it, Visa was a document which allowed persons to enter other countries (since 1920s, right?). Then Bank of America named their ( ? ATM-) cards ( wait, were there ATMs in 1976) as VISA cards because, I guess, of the name's popularity and being seen as a symbol of acceptance. Now doesn't it create a confusion between the 2 uses? I mean wasn't "Visa" trademarked by countries or something? Then tomorrow a company could call its ( debit / credit ) card as a "passport" without any problem, right? I understand that brands are always trying to create an allusion to something more than what the product aspires to be like, I guess, WINDOWS is for a PC (a window to a virtual world), but this is something different. I cant explain my confusion and chagrin quite neatly with that example, but... anyways have i got all these facts so far, right? And does anyone feel the same way about this ?
