Cost Examples and Choosing an Acceptance Set-up
POS card machine: rent, buy or use tap-on-phone? Costs and payback for Indian shops
How card terminal pricing works in India (rental, waivers, purchase, Android POS, mPOS and tap-on-phone), with a worked buy-vs-rent payback and contract points.
A card terminal (POS machine) costs a merchant in two ways: the MDR on each card payment, which depends on the card and your agreement, and the device cost, which can be a monthly rental (often waived above a monthly sales target), a one-time purchase, or almost nothing if you use tap-on-phone acceptance on a compatible Android phone. Buying pays back only if the rental you avoid, minus maintenance, SIM and repair costs, recovers the price within the time you will stay with the same acquirer. For many small shops that meet a waiver target, renting costs nothing; for a shop that misses the target, a purchase or tap-on-phone can save thousands a year. This guide shows how to decide. It belongs to the best-fit method.
Types of card acceptance devices
| Device | What it is | Tends to fit | Watch out for |
|---|---|---|---|
| Countertop terminal | Fixed terminal on wired or SIM connection | Shops with one billing counter | Fixed location, cables |
| Android POS (smart POS) | Touch-screen terminal running apps; often includes printer, QR and billing | Retail, restaurants, pharmacies | Higher price or rental; app lock-in |
| Mobile POS (mPOS) | Small card reader paired with a phone | Field sales, home services | Phone battery and compatibility |
| Tap-on-phone (SoftPOS) | NFC phone becomes the terminal through an app | Low-volume card acceptance, delivery | Contactless limits without PIN, compatible phones only |
| Terminal with soundbox and QR | Combined device | Counters with mixed UPI and card | Rental may be higher |
The RBI's contactless rules let cardholders pay small amounts without PIN up to a limit; above that, PIN is needed. Check the current limit with your acquirer; it affects whether tap-on-phone suits your ticket sizes.
How terminal pricing works
All figures are illustrative; ask for written prices.
| Element | Forms | What to ask |
|---|---|---|
| Rental | Monthly, debited from settlement | Waived above what monthly card value? Is UPI counted? |
| Purchase | One-time price | Locked to the acquirer? Warranty? |
| Security deposit | Refundable | Refund timeline |
| SIM/data | Included or extra | Annual price after first year |
| Paper rolls and accessories | Usually extra | |
| Maintenance (AMC) | For purchased devices | Price; what is covered |
| Minimum MDR or minimum monthly fee | Sometimes | Removes the benefit of low sales |
| Exit | Return of rented device, closure charges | Penalty if lost or late |
Worked example: rent or buy (illustrative)
A hardware store expects card sales of ₹1,20,000 a month. The acquirer offers:
- Rent: ₹600 a month (₹7,200 a year), waived if monthly card sales exceed ₹2,00,000. The store will not reach the target.
- Buy: ₹15,000, with a ₹3,000 discount for a 24-month commitment; owning still needs a ₹1,200 yearly maintenance and SIM plan.
In the payback calculator: cost ₹15,000, subsidy ₹3,000, yearly saving ₹7,200 − ₹1,200 = ₹6,000, increase 0%, horizon 3 years:
| Output | Result |
|---|---|
| Net upfront cost | ₹12,000 |
| Purchase recovered after | 2 years |
| Net saving over 3 years | ₹18,000 − ₹12,000 = ₹6,000 |
If the store would reach the waiver target, the rent is zero and buying loses ₹12,000 plus maintenance. If it might switch acquirer within two years, the purchased device may not work with the new acquirer, and the saving disappears.
Tap-on-phone alternative. If most card payments are small and contactless, a tap-on-phone app may have no device fee at all, only MDR. The store could test it with a few customers before committing.
MDR does not depend on owning the device
Whether you rent or buy, the MDR per card type is set in your agreement. Some offers bundle a lower rental with a higher MDR, or the reverse. Compare the total: rental + MDR on your card mix. For ₹1,20,000 of card sales, a 0.2 percentage-point difference in MDR is ₹240 a month, which can outweigh a ₹200 rental difference. The offer comparison guide shows how to compute the effective rate.
Contract points that cost money
- Waiver conditions: card value only, or card plus UPI? Calendar month or rolling?
- Lock-in: months you must stay; charge for early closure.
- Price changes: notice period for rental or MDR changes.
- Device swap: who pays if the terminal fails; turnaround time.
- Dormancy fees: some agreements charge if no transactions occur.
- Return: how to return; get a receipt to stop rental.
Who may provide terminals
Banks provide terminals directly. Non-bank companies that aggregate in-person payments operate as payment aggregators – physical (PA-P) under the RBI's 2025 Master Direction and were required to apply for authorisation by 31 December 2025. Check that your provider is authorised or is a bank. See payment aggregator rules.
FAQ
Can I use one terminal with two banks?
Usually a terminal is tied to one acquirer. Some Android POS devices can run several apps, but check with the provider.
Is the rental charged when the shop is closed for a month?
Usually yes, unless you have formally paused or returned the device.
Is tap-on-phone secure?
It works within the card networks' and acquirer's security rules. Follow the app's instructions, keep the phone updated, and do not use rooted phones.
Does a terminal accept UPI too?
Most modern terminals display a dynamic UPI QR; UPI pricing follows the UPI rules, not card MDR.
