The administrating system is configured to calculate places and a number of packages of shuffled playing cards at places of the backyard, the places of playing tables, places of carriers and the disposition place using information obtained by the loading step and unloading step and the administrating system calculates by every ID codes bases 1) places of packages registered by the registering step for registering to a data base of administrating system and a number of packages place by place from information obtained from the loading step and the unloading step. The administrating system is configured to recognize whether there is a lost package by comparing the information of all ID codes registered in registering steps with the ID codes at places of packages obtained at the calculating step from the loading step and the unloading step. ## Claims ### Claim 1 A method for tracking movement of a plurality of packages of playing cards in an entertainment facility, the method comprising: obtaining an ID code of at least one package of the plurality of packages when the at least one of the package comes into a detectable range of an ID code sensor; generating an event signal including information on the obtained ID code and a location of the obtained ID code when the at least one package of the plurality of packages enters the detectable range, departs the detectable range, or both enters and departs the detectable range; periodically creating, based on the generated event signal, an event record including information on the obtained the ID code, a time of obtaining the ID code and a location of obtaining the ID coded; and writing the created event record into a database. ### Claim 2 (depends on 1) The method according to claim 1, wherein periodically creating the event record includes: generating a first event record for the at least one package at a first time; receiving an indication to generate or update the first event record; and generating a second event record for the at least one package at a second time. ### Claim 3 (depends on 2) The method according to claim 2, wherein periodically creating the event record further includes determining the second time based on a duration for updating event records. ### Claim 4 (depends on 2) The method according to claim 2, further comprising writing the second event record to the database or updating the first event record with the second event record. ### Claim 5 A tracking system for monitoring and recording movement of packages of playing cards in an entertainment facility, the system comprising: a plurality of ID code sensors configured to obtain an ID code and generate an event signal responsive to obtaining the ID code, wherein the event signal includes information on the obtained ID code and a location of where the ID code was obtained in the entertainment facility, wherein the ID code is affixed to a package of playing cards; a database configured to store event records, wherein a particular event record of the event records includes information indicating the obtained ID code, a time of detection of the ID code, and a location of the detection of the ID code; and a processor communicably coupled to the database configured to generate the event records based on the event signals, wherein the processor is configured to generate or update the event records periodically based on the event signals generated by the plurality of ID code sensors. ### Claim 6 (depends on 5) The tracking system according to claim 5, wherein: at least one of the ID code sensors is installed at a storage area of the entertainment facility where the packages are stored, and at least one of the ID code sensors is installed in an forwarding area where each of the packages are in transit in the entertainment facility. ### Claim 7 (depends on 5) The tracking system according to claim 5, wherein each ID code sensor of the plurality of ID code sensors is configured to obtain the ID code when the package enters a detectable range of the ID code sensor, departs the detectable range, or both enters and departs the detectable range. ### Claim 8 (depends on 5) The tracking system according to claim 5, wherein the processor is further configured to determine whether the package of playing cards is missing by comparing a particular event record to at least one of the event records stored at the database.
