To use this app I have provided a google drive link below. Just click on it and download the apk on your phone and you are ready to go!!! some credentials:

for employee & security login:

username : vgssam2003@gmail.com

password : 123

for employee email in visitor you can use this email : vgssam2003@gmail.com.

while registering in visitor you need to write employee email as vgssam2003@gmail.com as you can login as an employee only on this email

I have also attached a ppt for the project you can look into it if you just want a quick glance at the project.

P.S ONLY The first response takes around 50 seconds loading time as the server is deployed in render and with less activity it spins down :))
