the following description of my novel method , together with its associated system for identifying the checked baggage of &# 34 ; no show &# 34 ; passengers , ( passengers that fail to board an aircraft ) carries the presumption that this is a highly suspicious situation or circumstance that should be investigated and that the baggage must not be allowed to be loaded or if previously loaded , should be removed . referring now to the drawing , it will be seen that with the system i propose , optimum results may be achieved in preventing the loading of the previously described undesirable baggage . the present airline procedures utilize a system whereby each ticket 10 and each claim check 24 is identified by a unique number , or if the baggage has been loaded , its easy and rapid identification and removal . i propose that tickets 10 and baggage claim checks 24 be imprinted with unique code numbers that are machine readable , in much the same manner as bank checks . they may also be provided with any one of the presently known machine readable bar codes as will be later described , in greater detail . the expression &# 34 ; code number &# 34 ;, as hereinafter used , refers to any distinctively coded , machine readable data and is meant to include any one or any combination of the following : numbers that have been printed with magnetic ink ; any &# 34 ; bar code &# 34 ; system such as the vertically arranged , parallel bars , used in supermarkets to identify the various items for sale ; the bars used by the postal service to designate the various zip codes ; any concentrically arranged circles forming a &# 34 ; bulls eye &# 34 ;, as well as any other coded data provided it is in a machine readable format . the ticket and claim check code numbers will then be entered into the airline computer memory bank 18 by means of either automatically scanning the number code and / or bar code , or by a manual , direct keyboard entry 19 . tickets 10 will then be distributed to airline ticket agents or travel agencies 12 , and the claim checks 24 distributed to baggage handlers in the same manner currently practiced . the information so derived may be used to indicate the airline ticket agent or the travel agency 12 , as well as the baggage handler , to whom the ticket was assigned . tickets are frequently sold and issued 12 to passengers at the ticket counter , by an agent of the airline , or at a travel agency that has a computer terminal and the authority to access the airline computer . in the normal course of events , the reservation will be confirmed and a boarding pass with a seat assignment will be issued . according to my novel system , now , the ticket code number is scanned again and loaded into the computer memory 18 , together with any other pertinent information ( passenger name , address , credit card or other billing information , etc ). this latter entry may also be done by any of the many automatic scanning devices currently in use , or in the absence of an automatic scanner , the ticket code number may be entered manually 19 , via the terminal keyboard . thus , every ticketed passenger now has a uniquely different , identifying number . this procedure neither delays nor inconveniences the passenger and is entirely compatible with the vast majority of tickets that are currently being sold and processed . for those passengers holding tickets that were issued at a travel agency that has no computer terminal or other access to the airline computer , my check - in procedure requires that the passenger report to the airline ticket counter , or to the check - in counter at the boarding area , in order to confirm his reservation and obtain a seat assignment and boarding pass . this gives the airline the opportunity to capture the necessary ticket code number and enter it into their computer memory 14 , 16 . should there be any changes in any of the seating assignments , flight plans etc ., or if any other transaction is made , each such change or alteration will be entered 14 , accompanied by the unique ticket code number now used for identification . thus , with the information now stored in the computer memory , it is a simple task for the computer to to then consolidate all of the transactions since they are all keyed to the unique passenger ticket code number identification . the next step in my novel procedure addresses the handling of baggage during the check - in process upon the arrival of the passenger at the airline terminal building 22 . normally , baggage is processed either at curb - side or at the ticket counter . in either event , a baggage claim check 24 , consisting of a tag portion and a receipt portion , with both portions also bearing a unique claim check code number , similar in type to that used on the ticket . customarily , when baggage is presented for check - in at curb - side , the tag portion is affixed 26 to the baggage and the receipt portion is either given to the passenger if a ticket is to be purchased at the counter or , if the passenger has a ticket , it is affixed to airline ticket 10 . at this point , various check - in scenarios are possible . for example , if the passenger possesses a ticket 10 , indicating a confirmed reservation , and has a previously issued boarding pass with a seat assignment then , during baggage check - in , the code numbers on the ticket , the boarding pass and any checked baggage receipt are scanned 28 at the curb - side check - in station , to enter the ticket and baggage code number information into the computer memory , after which , the passenger proceeds to the boarding area . in another situation , the passenger arrives at terminal 22 with baggage for check - in at the curb - side station with a ticket but with no boarding pass and no seat assignment . in this event , the baggage is checked in and the tag portion of the baggage claim check 24 is affixed to the baggage 26 . the code number portions of both baggage claim check 24 and ticket 10 are then scanned 28 for entry into the computer memory . the passenger is then required to check in at the ticket counter to confirm his reservation and get a boarding pass and seat assignment 14 . at this time , the agent has an opportunity to re - scan 16 the code number portions of ticket 10 , baggage claim check 24 and the boarding pass 14 , either to enter , or to confirm , that the data is in the airline computer system . the passenger may now proceed to the boarding area . alternatively , the passenger may go directly to the boarding area to obtain his boarding pass and seat assignment . in this event , after a boarding pass 14 is issued , all of the code number information is re - scanned 28 and entry into the computer memory confirmed , just as it would have been had the passenger gone to the ticket counter instead . yet another check - in situation arises where a passenger arrives 22 to check baggage 26 at the curb - side station without a ticket , intending to purchase , or pick up a ticket ordered earlier over the telephone . the passenger may opt to have the baggage checked and get a code numbered claim check that will be scanned 28 at curb - side , or forego the curb - side check - in and transport the baggage to the ticket counter where the ticket is either issued , or picked up . the ticket agent will also issue a boarding pass with seat assignment 14 , and a claim check 24 and , in not done earlier , will issue a code numbered claim check and affix the tag portion 26 to the baggage . the agent now has the opportunity to scan and capture 16 , 18 , or re - scan and confirm that all of the necessary passenger , baggage and seating information , is in the computer memory 20 . the passenger may now go to the boarding area . at this point in time , the passengers and baggage go their respective ways to the aircraft . upon entry of the passenger and baggage information , the computer correlates the information received to match and assign the various pieces of baggage to each passenger ( 30 ) as well as perform other desirable functions . the passengers , when boarding the aircraft , are required to surrender the ticket 10 ( if they had not been asked to do so earlier ), and the code number portion of ticket 10 is again scanned 32 . the ticket code number information so derived is then sent to the airline computer memory where the computer generates a list of passengers 34 that are aboard the aircraft . the baggage tag code number portions of the checked baggage are also weighed and scanned 38 in order to generate a list of the baggage that may be allowed aboard the aircraft . this latter step is done by matching the baggage claim check code numbers , entered into the system memory during check - in , with the list of boarded passengers . while the foregoing description of the operation of my novel security system has been presented in terms of scanning code numbered tickets and baggage claim checks , it should now become obvious from a reading of this exegesis , that alterations may be made to my system , without departing from the inventive concept . for example , one embodiment would utilize the addition of code numbers imprinted on the boarding pass / seat assignment care to accommodate some airlines . in certain instances , an airline may require that the passenger surrender his code numbered ticket at the boarding area , prior to actually boarding the aircraft . the passenger then proceeds , on his own and unattended , to board the aircraft by traversing either down an elevated boarding ramp or across the tarmac to the aircraft . in either event , the terrorist is provided with an avenue of escape . if this be the case , the boarding pass / seating assignment 14 card is provided with a detachable , code number portion , that may be similarly coded and read as are the ticket 10 and claim check 24 . the code numbered , detachable portion is then collected by an attendant at the time the passenger physically arrives at the aircraft , and is boarded . the code numbers are then scanned and the passenger list generated for use as previously described . thus , all possible scenarios by which terrorist &# 34 ; no shows &# 34 ; may have previously been able to get undesirable baggage aboard an aircraft have been prevented since , if any claim check code number information is present in the system , without corresponding ticket and / or boarding pass / seating code number information , the system will quickly indicate that the information is missing . the code numbered claim check list will then be used to identify the offending baggage 42 , which will then be removed if loaded 44 , or separated if not loaded , to await possible identification by a later entered code for a passenger that may have been on standby status . after all properly identified baggage is loaded , any remaining baggage is removed entirely if no further valid identification or explanation is forthcoming . other advantages are achieved by using my novel security system . for example , two lists are generated ; the first is a list of the passengers aboard the aircraft , arranged by seat assignment and the second is a list of the loaded baggage , identified by passenger . such lists will serve to keep track of passenger and baggage destinations , within the system , and as a check for the baggage loaders and minimize losing or misplacing baggage . it could also provide a means for quickly finding any lost or misplaced baggage . an additional advantage may be derived by weighing the baggage ( 38 ), while reading the claim check code number , and programming the computer to perform the required weight and balance calculation 43 to assure the pilot ( and the airline ), that the center of gravity ( c . g .) of the aircraft , when loaded with fuel , passengers , baggage and cargo , is maintained within the weight - c . g . envelope design parameters , and that the weight and balance calculations have , in fact , been made and are met . while the above - described security system has been set forth in terms of aircraft passenger and baggage surveillance , i do not wish to be so limited . it will now be obvious that my system has equal applicability for the security maintenance of bus lines and seagoing vessels , as well as any other means of transporting the public .
