It would prohibit gambling businesses from accepting credit card or bank transfers to fund online wagering. It also would prohibit credit card companies and banks from transmitting electronic payments for the purpose of online wagering. UNLESS you are wagering on horses (can you smell the lobbying exemption, people?) -- but any other sort of online games of chance... lotteries, poker, craps, slots etc. ... would fall under the new law.
I should point out that it contains no penalties or prohibitions on actually *wagering* for individuals, so really it's pretty useless (where there's demand supply will follow). But it does make it potentially a lot more difficult to get your wagering accounts funded -- again, unless you're wagering on horses.
ripley.
