Yes, it is possible to actually write a check and mail it to some online poker rooms. The downsides to this are speed and security. Obviously, it will take a while for your check to get through the mail and then be processed at the poker room. The mail is also not encrypted like online transactions are. If someone feels like opening your envelope, like any other piece of mail, they can.
In addition, many sites offer checks as a cashout option and for some they are the only option. A major negative for checks is that they often take a long time to be processed and sent to the player.
It remains to be seen whether or not U.S. banks will be required to track every paper check to see which are going to online gambling sites. If they do not, then for U.S. customers, paper checks may eventually be the way to go, like it or not.
