The most important things in ticket printing are serial numbers and barcodes for tracking tickets in ticket distribution and confirming awarded numbers. NASPL[1] provides a standard[2] of barcodes printed tickets combined with 52 bits as in [Table. Example of 52-bit combination barcode of NASPL]. The most important thing in ticket barcode design is that every ticket must have the unique identification system.

   Each identification number of tickets used in Korea has a serial number for tracking ticket packaging and distribution and a verification number for confirming an award grade. The verification number is printed not to be seen to a customer by being located below scratch. Each barcode and each serial number made with numbers are printed on a graphic area so that they can be seen with eyes during distribution, and distribution of tickets can be managed by scanning barcodes.
