The purpose of a carry-on baggage "verifier" would solve the common action of oversized and overweight baggage being brought on board, taking up precious space that could be utilized by all passengers. It would also allow air carriers to collect the fees of baggage that would normally be checked in at the counter.

The "verifier" would check the carry-ons weight and size to confirm it meets the carry-on baggage required limitations set by the airlines. Once the requirements of the baggage size is met, a method of confirmation would be provided to the passenger to place on their carry-on luggage.

Other than the standard tubular racks provided, there are no existing method, other than the gate attendants, to inform passengers that their carry-on excedes the size and/or weight per airline requirements. Given the fact that gate attendants are usually busy taking care of other duties to insure a smooth boarding, something that assist them would be benefitical. The airlines would also benefit from checked on baggage losses due to passengers avoiding the established carry-on requirements.

The "verifier" would be a simple construction of composite, plastic or sheet metal self standing apparatus. Mounted on four posts would be optical sensors that face each other and set at a calibrated height from the bottom plate of the apparatus. The bottom plate would be a made from a lightweight composite or plastic that is able to move from the weight of the inserted baggage. A sensor or switch would be mounted under the bottom plate. The apparatus would have a dispenser mounted on the side of the apparatus which would produce a colored label or other determined method of identification indicating that the luggage has been "verified", passing size and weight requirements. There would be a process panel on the apparatus with pictures showing the steps to take.

The process begins with the passenger placing the luggage into the "verifier" and pushing the green button on the process panel. If the weight of the luggage exceeds the maximum allowed, the sensor or switch under the bottom plate is actuated and the red indicator light will illuminate at which time the passenger would need to remove the luggage from the apparatus to take to the gate attendant to process for check on luggage. If the weight of the luggage is less than the maximum allowed, the optical sensors on the four posts would activate to now check the physical size. If the beam of those sensors are blocked, the luggage exceeds the size requirements and the red indicator light will illuminate. The luggage would then need to be checked by the gate attendant. If the sensors are not blocked, the luggage is within size, the process panel green light will come on and the dispenser produces a colored label or other. The passenger then removes the luggage from the "verifier", places the colored label, or other, from the dispenser on the luggage for the gate attendant to see when boarding the aircraft.
