A method of examining a product inspection, which is applied to a data management system comprising a database storing a plurality of product items which are corresponding to a plurality of products, wherein an identification tag is placed on each of the plurality of products; the identification tag has a tag code which is corresponding to one of the products; the method comprises the steps of: A. performing an inspection step multiple times, wherein the inspection step comprises the steps of: A1. reading the identification tag on one of the products by at least a tag reading device to obtain one corresponding tag code, which is performed by at least an inspector; A2. after obtaining the tag code, transferring the tag code and a corresponding inspection data to the data management system; and A3. according to the received tag code, recording the received inspection data in the product items which are corresponding to tag code, which is performed by the data management system; B. providing a first electronic device connected to the data management system; selecting a plurality of product items from the product items in the database through the first electronic device, which is performed by a first party; C. generating a check code which is corresponding to the selected product items in the step B and writing the check code to a data of the selected product items in the step B, which are performed by the data management system; generating a notification message which is corresponding to the check code, which is performed by the data management system; D. providing a second electronic device connected to the data management system, wherein the notification message is sent to the second electronic device; responding to the notification message through the second electronic device, which is performed by a second party; and E. obtaining check items from the database according to the check code which is corresponding to the notification message that is responded by the second party, and then examining the inspection data of the check items, which are performed by the data management system; if the examined inspection data of each of the check items satisfies a check condition corresponding to each of the check items, transferring the check items satisfying the check condition to the second electronic device, which is performed by the data management system. A. performing an inspection step multiple times, wherein the inspection step comprises the steps of: A1. reading the identification tag on one of the products by at least a tag reading device to obtain one corresponding tag code, which is performed by at least an inspector; A2. after obtaining the tag code, transferring the tag code and a corresponding inspection data to the data management system; and A3. according to the received tag code, recording the received inspection data in the product items which are corresponding to tag code, which is performed by the data management system; A1. reading the identification tag on one of the products by at least a tag reading device to obtain one corresponding tag code, which is performed by at least an inspector; A2. after obtaining the tag code, transferring the tag code and a corresponding inspection data to the data management system; and A3. according to the received tag code, recording the received inspection data in the product items which are corresponding to tag code, which is performed by the data management system; B. providing a first electronic device connected to the data management system; selecting a plurality of product items from the product items in the database through the first electronic device, which is performed by a first party; C. generating a check code which is corresponding to the selected product items in the step B and writing the check code to a data of the selected product items in the step B, which are performed by the data management system; generating a notification message which is corresponding to the check code, which is performed by the data management system; D. providing a second electronic device connected to the data management system, wherein the notification message is sent to the second electronic device; responding to the notification message through the second electronic device, which is performed by a second party; and E. obtaining check items from the database according to the check code which is corresponding to the notification message that is responded by the second party, and then examining the inspection data of the check items, which are performed by the data management system; if the examined inspection data of each of the check items satisfies a check condition corresponding to each of the check items, transferring the check items satisfying the check condition to the second electronic device, which is performed by the data management system.
