A preferred embodiment is directed to a method of RFID power ramping (174) for tag singulation that includes activating the trigger control (12) of an RFID reader (2) for engaging power to begin reading RFID tags (4, 40, 41, 42, 43, 44). A user may take a first reading at a low power level (151) of a volume around the RFID reader establishing a first read volume. If the user does not detect a particular RFID tag, the user may then increase the transmitting power from the RFID reader to a second higher power level (152) obtaining a second reading of RFID tags in a second read volume. The user may once again increase the transmitting power from the RFID reader to a third higher power level (153) obtaining a third reading of RFID tags in a third reading volume. Increasing the RFID transmitting power is repeated until there is a final read volume where the operator reads and recognizes the detected RFID tag.
