The United States Court of Appeals for the Fifth Circuit ruled in November 2002 that the Federal Wire Act prohibits electronic transmission of information for sports betting across telecommunications lines but affirmed a lower court ruling that the Wire Act "'in plain language' does not prohibit Internet gambling on a game of chance." But the federal Department of Justice continues, publicly, to take the position that the Wire Act covers all forms of gambling.
The money for online gambling can come from credit card, electronic check, certified check, money order, wire transfer, or cryptocurrencies. Normally, gamblers upload funds to the online gambling company, make bets or play the games that it offers, and then cash out any winnings. Gamblers can often fund gambling accounts by credit card or debit card, and cash out winnings directly back to the card; most U.S. banks, however, prohibit the use of their cards for the purpose of Internet gambling, and attempts by Americans to use credit cards at Internet gambling sites are usually rejected. A number of electronic money services offer accounts with which online gambling can be funded.
