Methods and systems for efficiently communicating information to/from an RFID reader are provided. According to one embodiment, a command is received by a Radio-Frequency Identification (RFID) reader from a handheld computer via an audio connection of the handheld computer. Responsive to the command, a tag scanning process is initiated by the RFID reader to cause all RFID tags within range of the RFID reader to communicate their unique IDs to the RFID reader. A unique ID of an RFID tag is received by an RFID transceiver of the RFID reader. Responsive to receipt of the unique ID, the RFID reader: (i) assigns a short tag ID to the RFID tag and creates an entry in a table having stored therein the short tag ID and the unique ID; and (ii) reports detection of the RFID tag by transmitting to the handheld computer the short tag ID and the unique ID.
