An ETM machine (electronic ticketing machine) is the handheld device a bus conductor uses to issue printed tickets. The conductor selects the passenger's destination stage and the ticket type, and the ETM calculates the fare from a fare table stored inside it, prints the ticket in a second or two, and saves a record of it. At the end of the day the machine produces a collection report, so the cash the conductor hands in can be checked against every ticket sold. ETMs replaced the punched paper tickets and ticket racks that conductors carried for decades.
They are now standard on state transport buses: TNSTC has put electronic ticketing machines in 700 of the 800 buses in its Nagercoil zone. Private bus operators in Tamil Nadu and Kerala use them for the same reasons: accurate fares, a ticket with the bus number on it, and a daily record of collections. This guide explains how a bus ticket machine works, how it compares with paper tickets and phone apps, and what to check before you buy one.
1. How a Bus Ticket Machine Works: A Conductor's Day
An ETM follows the shape of a bus duty. On a Clancor MP7510 running our bus ticketing app, a typical day looks like this:
- Open the day. The conductor logs in and opens the day sheet (waybill): route, bus, permit number, driver, conductor and direction of travel. Every ticket printed after this carries those details.
- Issue tickets stage by stage. For each passenger the conductor keys in the destination stage and the ticket type: full, half (child), luggage, group or pass. The machine looks up the fare between the current stage and the destination, prints the ticket, and adds it to the trip total.
- Move through the stages. As the bus passes each fare stage the conductor moves the machine on to the next stage (the STAGE+ key on the MP7510), so the next tickets start from the right boarding point. The REPEAT key issues the same ticket again for a queue of passengers going to the same stop.
- Close the trip. At the terminus the conductor closes the trip and the machine prints a trip summary: tickets by type, passengers and collection.
- Close the day and hand over. After the last trip, the day-close report shows the total to be handed in. The ticket data then goes to the office: by USB stick, by SMS summary, or uploaded online, depending on the version of the app.
Where the fares come from. Routes, stages and fares are set up once on a computer in the office, then loaded onto every machine. Fares can be a stage-to-stage table (each pair of stages has its own fare) or a linear scale (fare rises by a fixed amount per stage). When fares change, the office updates the table and reloads the machines; conductors never calculate a fare by hand.
Offline, SMS or online. An ETM does not need the internet to print tickets. The three common setups are:
- Offline: tickets are stored on the machine and collected at the depot by USB. Lowest running cost, works on any route.
- SMS: the machine also texts a trip summary at each trip close and a day summary at day close to the owner's phone, so collections are visible the same day without an internet plan.
- Online: tickets are uploaded over mobile data (2G) or Wi-Fi to a web dashboard, so the owner sees every bus's collection as the day runs.
2. ETM vs Paper Tickets vs a Mobile App
| Factor | Paper ticket book | Phone ticketing app + Bluetooth printer | Handheld ETM |
|---|---|---|---|
| Fare accuracy | Conductor calculates or reads a chart | Calculated by the app | Calculated from the stored fare table |
| Record of every ticket | Only the stubs and counterfoils | Yes, if the phone is not lost or reset | Yes, stored on the machine and sent to the office |
| Bus number and route on the ticket | Only if pre-printed | Yes | Yes, from the day sheet |
| Speed in a crowded bus | Fast for one fare, slow with change and stages | Two devices to hold; Bluetooth can drop | One hand-held unit with keypad and printer |
| Trip and day reports | Manual tally at the depot | Depends on the app | Printed on the machine; sent by USB, SMS or online |
| Works with no network | Yes | Often needs data to sync | Yes; online upload is optional |
| Built for daily bus use | Yes | Consumer phone, not drop-rated | Rugged body, full-shift battery, keypad usable on the move |
The bus number matters more than it looks. In Kerala, transport officials say that under the rules tickets must include the bus number, and Onmanorama reports that some private operators fall back on blank tickets printed only with the word "bus" when their machines break down. A reliable ETM that prints the bus number on every ticket keeps an operator on the right side of that rule.
3. What to Check Before You Buy a Bus Ticket Machine
- Fare setup that matches your routes. Check that the machine supports stage-to-stage fare tables as well as linear fares, and the ticket types you sell (child, luggage, group, passes). Ask how fares are updated and how long it takes to reload a fleet.
- Printer and paper. A 2-inch (58mm) thermal printer is standard. Look for a print speed of at least 50mm per second so the queue keeps moving; the MP7510 prints at over 55mm/s.
- Battery for a full duty. A conductor's day can run 12 hours or more. A 7.4V / 2,600mAh Li-ion pack is a common size for a full shift of ticketing.
- Built for the bus, not the shop. Look for a drop rating (the MP7510 is rated for a 1m drop onto concrete) and an operating range that covers Indian summers (the MP7510 runs from -20°C to 50°C).
- Connection you can afford to run. Decide whether offline, SMS or online reporting suits your fleet before you buy, and check whether the machine can move to a higher version later without being replaced.
- Language on the ticket. If passengers or inspectors expect Tamil, check the machine can print Tamil tickets, not only English.
- BIS certification and local support. Electronic equipment sold in India falls under the Bureau of Indian Standards registration scheme. Ask who repairs the machine, how fast, and whether spare batteries and printers are stocked.
Where Clancor fits. The Clancor MP7510 is a BIS-certified handheld with a 2.8-inch colour screen, built-in 2-inch thermal printer and a 2,600mAh battery, listed at ₹9,999. It runs our bus ticketing app in offline, SMS and online versions, with separate Tamil Nadu and Kerala builds and Tamil ticket printing. Our earlier MP6320 handheld is used for bus ticketing too.

Frequently Asked Questions
What is the full form of ETM in bus ticketing?
ETM stands for Electronic Ticketing Machine (also called an electronic ticket machine). It is the handheld device a bus conductor uses to print tickets, calculate fares from a stored fare table, and keep a record of every ticket sold for the day's collection report.
How does a bus ticket machine calculate the fare?
The office loads the route's stages and fares onto the machine. The conductor keys in the destination stage and ticket type, and the machine looks up the fare between the current stage and the destination in its fare table, or applies a fixed amount per stage on a linear scale. Child, luggage and group tickets use their own fare rules.
Does an ETM machine need internet to work?
No. An ETM prints tickets and stores them on the machine without any network. Internet or mobile signal is only needed for optional reporting: an SMS version texts trip and day summaries to the owner, and an online version uploads tickets over 2G mobile data or Wi-Fi to a web dashboard.
Can a bus ticket machine print tickets in Tamil?
Some can. The Clancor MP7510 bus ticketing app can print Tamil tickets as well as English, which suits Tamil Nadu routes where passengers and checkers expect the local language. Check the language support of any machine before you buy, as many print English only.
How much does a bus ticket machine cost in India?
Handheld bus ticket machines in India are commonly priced from under ₹10,000 to ₹20,000 or more, depending on the screen, printer, battery, connectivity and software included. The Clancor MP7510 is listed at ₹9,999. Budget for paper rolls, a spare battery and, for online versions, a mobile data plan per machine.
