What are Electronic Ticketing Machines?
Electronic Ticketing Machines or ETMs are new generation automated ticketing machines that can manage numerous fare structures and ticket types. They are small, light-weight, handheld devices, that are used by conductors to print and issue tickets. ETMs make the whole process of issuing tickets easy and convenient. They also reduce the risk of any fraudulent practices and facilitate rich MIS.
Why ETMs?
The current practice of issuing tickets is fraught with many problems such as:
  • Cumbersome ticket sale reconciliation process for conductors
  • Greater risk of errors by conductors if they are not very familiar with the fare structure
  • Risk of cheating by conductors by reselling tickets and by issuing tickets of lower denominations
  • Circulation of fake tickets
  • Tedious process of drawing up the inventory, distributing and reconciling ticket stocks
  • Time consuming process of reconciliation of accounts by depot staff
  • Limited reports, as the entire ticket sale data is on papers
  • High cost
ETMs address all these problems faced by the current system. Since the tickets are printed on the spot and on special paper, it does away with the risk of fake tickets or the tedious inventory/distribution process. Even if conductors are not very familiar with the route or fare structure they need not worry as all the data is available in the machine itself. All details on the number of tickets issued to revenue collected are stored inside the machine, saving the conductor from the long drawn reconciliation process.
