 Bigger Bigger  Smaller Smaller  Reset Reset

The project I am working on requires multiple slave Bluetooth devices to be connected to a master(currently an arduino uno R3), but only one of the slaves can be accessed at a time. The slave device would be worn like a watch so they would be mobile but the master would be stationary.I was hoping to use RFID tags attached to the slave device to tell the master which slave to connect to. the only problem is that i don't know if i have enough serial ports. If i connect the bluetooth module to a software serial port, can I connect the RFID reader to the hardware serial ports and get two seperate readings on each? My concern is that the arduino needs to be able to work the two serial ports separately, though not at the same time.
Any help would be greatly appreciated.
