Citi bank easy checking.

It someone wants to steal your account info, it does NOT matter you pay them using online or paper check. On your paper check, it has everything they want to forge your check.

Just make sure your PC has not spy ware, no key loger, etc! A good and free way to start is install the ZoneAlarm (the free one). When any program of your PC wants to connect to internet, it will warm you (and you should deny internet access for as many program as you can).
