A bag unlocking method includes receiving, by a bag handling system, a bag during a check-in process. The bag handling system identifies, from a travel carrier system, traveler information corresponding to the bag. A securing device of the bag is programmed, using an unlock code pertaining to the traveler information. The bag handling system reads a bag tag of the bag at a baggage inspection station and determines the unlock code pertaining to the bag tag. The bag handling system transmits the unlock code to cause the securing device to unlock at the baggage inspection station.
