Case Study

School Gate Entry Solution

Poor internet in the area, untrained personnel & client wanted a manpower free solution at the gate.

The School had only 450 students and only one gate which was used both for entry and exit. From this same gate, students were going to the play ground also. However, the school did not want to capture entry to the playground, but wanted that it should capture data Only during school entry and exit

We decided to put a UHF RFID reader and entry and exit gate (Even though NFC solution was being provided for bus tracking). We proposed combi cards (both UHF and NFC) so that it would work for both gate and bus attendance capture.

Initially, After installing a UHF reader we were able to register only 40% students' data due to sub optimal placing of the level of the reader. We analyzed every parameter on ground and adjusted the reader accordingly and achieved getting 96% data. Subsequent investigations revealed that 2% students had not received their cards , 1.5% students forgot to bring their cards and 0.5% students kept their card inside their bags. We then sensitised the users to wear their cards around their neck and to bring cards on daily basis. Thereafter we achieved accuracy levels of 99.5%. (Out of 450 students present on campus, we captured the data of 445 to 448 on daily basis).

"We found that instead of using one reader there should always be 2 readers at the gate to get 100% efficacy. We also found that Main application system on local environment was erratic in the absence of trained IT person in school . In such cases We ought to have recommended usage of NFC (Minimum hardware based product) instead of UHF. Capturing and collection of student's data was a huge challenge for the school and before project commencement all student data, cards printing and mapping the cards ought to be completed prior to any commissioning work. This whole excercise could take 3 to 4 weeks and must be guided through a process oriented protocol. We also found that schools often insist on buying their own hardware ( NFC devices) themselves but it is better they procure through the vendor who can pre-check the compatibilty of the devices with the app, ultimately saving time and energy"
