A very common technique used in Hindu/Buddhist Japa Meditation is to count the phalanges/creases in each finger including the tip thus making 4x5=20 count in one hand. For each 20 count of the right hand use 1 phalange/crease of the left hand and thus you can easily count upto 20x20=400 in a single complete cycle.
