Abstract: Items associated with radio frequency (RF) identification (RFID) tags sequentially arranged in a list are to be retrieved from a venue. A mobile RFID tag reader is jointly movable with an operator. The reader is controlled to non-sequentially read the tags from the list. The operator is guided to find any one of the items by reading the tag associated with the any one item. The operator is prompted to retrieve the any one item and to remove the associated tag from the list. The guiding operation to the any one item is discontinued after retrieval of the one item. The guiding operation, the prompting operation, and the discontinuing operation are repeated for any others of the items from the list in a non-ordered sequence.
