The next time you plan to buy a ticket from the reservation counter, be prepared to provide your biometric data. In order to curb tout menace at railways, authorities are planning to install biometric authentication system before the reservation counter. 

To book a ticket, one would have to first take a coupon from the system, by giving their thumb impression. The centralised biometric system will allow only two coupons per person per day. If anyone tries to book multiple tickets, the system will alert officials.
