Sometime this summer, the validator screens will go live, and anyone with a turquoise card will be able to tap their way onto the trains. This means the days of standing in line at a SEPTA counter to purchase a paper ticket and then submitting the little card to a train conductor to be hand-punched will soon be over. The cost of the trip will simply be deducted from your Key card balance when you step through the turnstile. As a bonus, improvements to PATCO's ticketing system should soon make it possible for its riders to use their passes on SEPTA.
