Strip leading '10' from item_id
    The ID submitted by the RFID-readers on our self-checkin machines contains
    the numbers '10' before the actual item id (barcode). We don't know what it
    means or why it's there, but in order to match the barodes in the database,
    we have to strip them away. This is off course just a temporary fix.
