Full Tilt Poker has begun offering Instant eChecks as a deposit option for select members. If Full Tilt makes Instant eChecks widely available, it will become just the second U.S.-facing poker room to offer this option.
PokerStars began offering Instant eChecks in August.
Instant eChecks use Electronic Fund Transfers to transfer money from checking accounts to player accounts. At
PokerStars, players need to provide the routing and account numbers for their banks in addition to social security numbers, date of birth and phone numbers.
I little tip since poker sites are outside the USA and could be hard to run down set up a seperate bank account just for your gaming transactions if your going to give out you bank account routing and access numbers. Only keep enough funds in the account for you gaming. You can ussally set on up for a low deposit amount.
