Yes, however, like your bank card or your passport, all your details and playing habits are stored on a central system, meaning that if you don’t return for 100 years, your name is still on the system, and the casino can pick you up where you left off, and usually they’ll bung you a few little added extras, unlike banks! As long as you have some form of identification any casino comp club should be able to issue you on the sport with another comp club card if you can no longer find your old one so never be afraid to ask!
