Are all VISA cards connected with bank accounts?
Not necessarily. You can issue credit cards without a bank involved, although companies which do so may have additional legal complications, such as usury regulations. As an example, AmEx is a network which also issues cards themselves. The company is not a bank; they sold their banking subsidiary in 2007. It's also possible to get a bank-issued credit card without banking with that same company.
