Should I throw away my card once I've played all of my rounds?

​NO!  Your Players Card account number is on the back of the card, and cards can be used year over year. When you purchase a new card each year, the new membership is added to your existing record. 

Additionally, team members can look up your Players Card rounds with your email address or phone number. You do not need to have your card physically on your person to use your rounds.
