REACTIVATION LOOP
The reactivation loop is used to process a device with
its FR bit cleared. A device in this loop waits for the
FRB command. If a device receives the FRB
command, it transmits the contents of Block 1 (Tag ID)
to its memory and waits for a MC2 in its listening
window. If the device receives the MC2, it leaves this
loop and enters the processing loop. This reactivation
loop has no anti-collision capability. It is designed for
reactivation of single devices. This loop can be
effectively used in retail store applications to process
returning items from customers.
