Happen to saw this in the news recently where some predefined activities in your daily life would act as trigger activity to pay a small premium for a micro insurance policy.

I thought it was a nice idea where it become micro purchases that might not seem to large and daunting. Wonder what are your views on it ? Pro , Cons, etc. I was thinking of starting small with a critical illness plan by SNACK and slowly accumulate coverage as i travel using my EZ link.
