I had the same experience last year.... this is the process if dowwan to attend court session:

- Wait around 3-5 days for your 'saman' to enter (and captured) into the traffic online system

- Check how much is the offense online and pay immediately if possible

- Print the receipt of payment and keep as proof

After doin all these, no need to attend court session d cos the system already captured your payment.

I didn't receive any letter (or reminder) to attend court after I did all these steps, so no worries....
