There are many more types of smart card but I prefer to use #Edsys smart card. It is very useful for student and for parent. By using this we can track school bus as well as we can purchase the student books.

Three Smart cards of Metro , one for Express line that connects New Delhi Railway station to Terminal Three and two smart cards (using one only on regular basis , bought a new one because this card was misplaced at that time) for other Metro operations in Delhi/NCR .
