Abstract
The present invention is a message updating system for an electronic label. The system comprises a message updating device, wherein a controller thereof controls a power-supply transmission unit and a message-update transmission unit to respectively transmit a charging signal and a message-updating to the electronic label for charging the electronic label and updating label information of the electronic label. A detection device picks up the label information to generate label content information, transmits the label content information to the controller to make the controller compare the label content information with update comparison information, and generates an alert message if the label content information is different from the update comparison information. The present can charge the electronic label that is mounted on an article and update label information simultaneously while the article is being transported.
