According to my friends who tried it, u need to fill the online form only once. After that, u need to “check registration” and you should receive a pdf document of your submission details. Then , you need to go queue the normal counter for the staff to verify one time. He will also stamp your passport. Then he will ask u to try the e-gate to enter. On exit , you would need to stamp out as you stamped in earlier. Then u can try the e-gate again. Subsequently , you do not need to fill in the form anymore. U can just use the e-gate directly.
