    An Xbee would work.

    thanks you for your help,
    will this device pick up any RF signal in a room,
    If i don't want any interference from other devices which might send out RF signals, wouldn't a bluetooth setup be better, and if so is there any bluetooth chips or devices that you might recommend.

    (PS: correct me if i'm wrong)

    Bluetooth with RS232 will cost much more than the $20 an XBee costs.

    Cost is not much of an issue, but say i do use an RF module is there a way i can 'pair the devices' like you can do with bluetooth. So in my case my LCD display will only get a signal from the balance board and not any other device in the room.
