can users earn point after a time period?

Hey guys, You just made a great plugin. I love it.

I’m willing to know is there any chance to make an ability all users get point after a time period but not instantly?

for now I made a rule for viewing post, when someone read a post get 10 points. but the system will credit user right after the page opened!
so many of our users doesn’t read and just open/close pages to get earn points.

so I need to specify a time period like 60s with a countdown timer and popup message to let user knows time is ended and they earned the point.

thanks for helping.
