6.2. Post-evaluation
The proposed system was developed in the lab setting first. We identified various system test cases in the system components including thin client with RFID backend, barcode backend, web frontend, login system, querying, and DB manipulation and integrity. The system was revised until it passed all the tests in the lab. After all the debugging and tests
were conducted in the lab, the system was demonstrated and tested on site several times with equipment shown in Fig. 7 for acceptance testing and further system revisions. We performed two major tests to evaluate the developed system's on-site performance and feasibility:
1) usability test and 2) environmental test.
