Daily maintenance checks are performed on civil aircraft to guarantee that they are always prepared for takeoff. Verifying the existence and expiration dates of life vests is part of this. However, there are a number of problems with the conventional manual inspection method. 

• Low inventory efficiency: It takes 30 to 60 minutes to check a single aircraft using the traditional manual inspection method. 
• High error rate: The chance of overlooked inspections is heightened by human factors. 
• Inadequate monitoring of expiration dates and challenges in retrieving inventory data contribute to ineffective management. 

The utilization of the AUTOID UTouch 2 RFID Mobile Computer provides HNA with the following benefits: 

• Compared to manual operations, the application of RFID technology has increased efficiency by more than five times. 
• Accuracy is greatly increased when real-time display is used during the inventory •process to avoid missing inspections. 
• Integrating life vest monitoring with the software management system allows for full-process information management.

Every life vest has an affixed high-reliability RFID tag. Information about each life vest can be efficiently and quickly obtained in real-time by utilizing the software system in conjunction with the AUTOID UTouch2 RFID Handheld Computer. This enables the inspection of every life jacket on an airplane to be finished in five minutes.
