The expression "put your hand in your pocket" is often used to suggest that someone should spend their own money on something. For example, if you're going out for lunch with a friend and you suggest going to an expensive restaurant, your friend might respond by saying "I can't afford that, you'll have to put your hand in your pocket if you want to go there." This means that if you want to go to the fancy restaurant, you'll have to pay for your friend's meal as well as your own. So, in essence, "put your hand in your pocket" means to offer or contribute money towards something.
