Taiwan had the same concern. What they did is make it so that receipts also work as lottery tickets, to encourage people to ask for them and hold on to them.
Not from Taiwan, but the way it works is that there’s a unique ID on each of the receipts. The ID is there anyways, so no additional things to be done at this point. What’s different is that a lucky ID is announced e.g. every month, and the person with the receipt can collect a small amount of money.
