what is grace period for metrocard
Don't waste your time trying to stock up on unlimited Metro cards. Unlimited-ride MetroCards purchased at today's prices will stay valid for trips after fares rise Dec. 30 - but not for very long. The MTA has set grace periods for each type of unlimited MetroCard that range from one day to six weeks. At the end, software at subway turnstiles and bus fareboxes will reject the MetroCards as payment.
