A process for electronic authorization to access a common account via personal identification devices such as Radio Frequency Identification (RFID) tags, such as may be mounted on a wristband. RFID wristbands for auxiliary users are not authorized by a cashier/operator unless a primary account holder's RFID wristband is utilized as an immediate preceding step. This process alleviates a problem with simpler approaches which merely require operator authorization to associate auxiliary RFID wristbands with primary RFID wristbands.
