An EEG POS system has an EEG device that detects electrical signals representing brain waves. A database of brain wave profiles represents a plurality of items to be identified. A live signal analyzer compares electrical signals from the EEG device with stored brain wave profiles in the database to identify entries in the database representing items that match the electrical signals from the EEG device, where items whose stored brain wave profiles match the electrical signals are considered identified items. A POS terminal is coupled to the live signal analyzer in order to log and tally items for a transaction.
