Mini ATM or AePS First? Cash Float and Location

You’ve seen a cash-withdrawal counter in a market and thought your shop could do the same. Then the questions start. Mini ATM or AePS? Which machine? How much cash do I keep? Will anyone even come?

Here’s the thing. The machine is the smallest part of the decision. What decides whether a cash service works at your counter is whether you can fund the cash, whether you sit where people need it, and whether the customers are there. This checklist is built on RBI and UIDAI documents. It gives no commission rate and no income figure, because none of those sources does.

What are you actually choosing?

Four words get used loosely in this business. Keep them apart.

• AePS is a payment system. RBI’s directions of 27 June 2025 say it is run by the National Payments Corporation of India (NPCI) and lets people transact “through Aadhaar number and biometrics or OTP authentication”. The services include cash withdrawal, cash deposit, fund transfer, balance enquiry and mini statement.
• A Micro ATM is a terminal, a device. RBI’s Payment System Report, December 2025 counts Micro ATMs separately from PoS terminals. It also says AePS works at “Point of Sale (Micro ATM) terminals”.
• A Business Correspondent (BC) is a bank’s retail agent. It’s the appointment under which you serve the bank’s customers.
• “Mini ATM” isn’t a term in the RBI documents we cite here. They say Micro ATM.

So when a seller offers you a “mini ATM”, ask what it does. A card-swipe cash device may or may not be the same product as the AePS Micro ATM. RBI’s circular of 20 September 2019 lists “Cash at PoS” among card transactions, but it doesn’t call that a mini ATM. Ask the seller to put the device’s supported transaction types in writing. Then you’re comparing facts, not names.

How much cash float do you need?

Float is the cash you keep on hand to pay customers. It’s easy to underestimate.

An older RBI-hosted paper on the micro ATM model expected the money for a withdrawal to come from the BC’s cash drawer. That paper carries its author’s personal views and uses data only up to March 2010, so treat it as the origin of the idea, not today’s rulebook. Whether your bank works that way is a question for the bank. If the bank expects you to pay out of your own drawer, settle the float before you think about any device. Ask what cap applies to the cash you may hold, and to single payments and receipts.

Cash also moves the other way. AePS includes cash deposit, so a deposit brings cash into your drawer and a withdrawal sends it out. The float you need on a given day depends on the mix of services, not just on which ones you offer.

A float worksheet using your own numbers

No source gives a standard float. So build yours.

1. Estimate how many withdrawals you might serve in the longest stretch between two refills.
2. Multiply that by the typical withdrawal amount you expect.
3. Add the cash your shop needs for its own sales, which must never be spent on pay-outs.
4. Check the total against any cap in your bank’s agreement.

Write the answer as one rupee figure and one date when you can next refill. If you can’t name both, you don’t have a plan yet. And if the figure is more than you can safely hold, don’t stretch the till. Reduce the service instead. Plan your refills around bank holidays too, because a shut bank means no refill.

Is your location right?

The sources don’t say where a cash service works. They do show what the bank looks at, so start there.

Ask which branch you’ll be attached to. Then ask whether any distance limit between your counter and that branch applies to you. Get the answer in writing.

Expect monitoring that includes your location. RBI’s AePS directions, effective 1 January 2026, require the acquiring bank to monitor AePS touchpoint operators and set parameters based on the operator’s business risk profile. Location, type of operator, and the volume and speed of transactions are part of its fraud risk framework. So be ready to explain what a normal day looks like at your counter.

An idle counter has a cost. If an operator has done no transaction for a continuous three months, the acquiring bank must carry out the operator’s KYC before enabling further transactions. A quiet counter can mean paperwork all over again.

Walk the area yourself. Note how far people live from the nearest branch or ATM, and which banks they use. No document can tell you that about your street.

Don’t lean on a national trend. The RBI report shows the Micro ATM count fell from 14.59 lakh at the end of June 2025 to 14.15 lakh at the end of December 2025. That’s the whole country over six months. It says nothing about whether your corner is a good one.

Who is your customer?

AePS customers use Aadhaar-linked bank accounts, with biometric or OTP authentication. So an AePS counter serves people who have such an account and whose authentication works. If a customer’s fingerprint doesn’t read, the counter can’t do much for them.

Any fingerprint device you use must be a UIDAI Registered Device. UIDAI’s biometric devices page says it “mandates usage of only Registered Devices in Aadhaar Authentication Ecosystem” and has moved from L0 to L1 fingerprint registered devices. Ask the seller for the device’s registered-device status and level. And ask who pays if the reader has to be changed.

What happens when a transaction fails?

Sooner or later a customer will come back saying money left the account but no cash came out. Know the rule before it happens.

RBI’s 2019 circular (RBI/2019-20/67) says that for ATMs including Micro-ATMs, a debit without cash dispensed must be reversed within a maximum of T + 5 days. If it takes longer, ₹100 per day of delay is credited to the account holder. T is the day of the transaction. For AePS, where the account is debited but the merchant location never gets confirmation, the acquirer starts a “Credit Adjustment” within T + 5 days.

A warning, though. That is the 2019 edition of the rule, not a confirmed current one. RBI’s Master Directions index now lists the Commercial Banks Responsible Business Conduct Directions, 2025. So ask your bank which timeline applies today. And give the customer something to carry: the slip or a screen record is what they take to the bank.

AePS operator or bank CSP: which role do you hold?

RBI’s documents describe overlapping roles. Your agreement decides which one is yours, so ask the bank directly.

• Business Correspondent. A retail agent engaged by a bank to give banking services away from a branch, according to an RBI discussion paper (an undated page that dates to 2010).
• AePS touchpoint operator. The individual onboarded by the acquiring bank to run an AePS touchpoint, per the June 2025 directions.
• Customer Service Point (CSP). In an RBI speech of 8 September 2015, BCs and Business Facilitators were allowed to act as a CSP for e-KYC. Confirm whether your bank uses CSP for the agent, the outlet or both.

The AePS directions let a bank adopt due diligence already done on a person as a BC or sub-agent. That suggests the roles can overlap, but it doesn’t mean every operator is a BC. RBI’s KYC Directions, 2025 for commercial banks (updated as on 1 October 2026) also let a bank use BCs for biometric e-KYC authentication, with the bank keeping the responsibility. KYC work is a different service from paying out cash, and it needs the bank to switch it on for you.

How do you read a commission schedule?

None of the RBI documents here sets a commission rate, and this guide doesn’t either. Pay terms sit in your agreement. So when a schedule lands in your hands, read it with these questions:

1. What’s the unit? A rate per completed transaction, or a slab that changes with amount or volume?
2. Do withdrawals, deposits and balance enquiries pay differently?
3. Are failed or reversed transactions paid?
4. Who pays you: the bank, or a company that manages BCs for the bank?
5. Are there deductions, and when does the money reach your account?

If a schedule can’t answer these, it’s not a base for planning your cash.

What should you get in writing before you commit?

None of the sources here sets a device price or the customer’s withdrawal fee. Get the current position from the bank, in writing.

Which one first?

Nothing in the sources ranks one service above the other. So let your own answers set the order.

• Can’t fund the float? Settle that before any device.
• Does your area depend on people with Aadhaar-linked accounts and working authentication? Then AePS is the service RBI describes at Micro ATM terminals.
• Does your bank offer only one of the two? Then the choice is already made.
• Still unsure about location and role? Wait. A written agreement is cheaper to ask for than to undo.

Questions about starting a cash service

Is a Mini ATM better than AePS for a small shop?

No source ranks them. The order above, cash first, then location, then role, is the useful way to decide.

Does AePS need a Mini ATM?

RBI describes AePS as working at Point of Sale (Micro ATM) terminals through Business Correspondents. The documents here don’t say whether another device type can be used. UIDAI requires Registered Devices for Aadhaar authentication.

Is UPI cash withdrawal an option?

This guide doesn’t compare it. Ask your bank whether it offers UPI-based cash withdrawal for agents, and on what terms.

What can SiOnline tell you about this?

This guide describes no SiOnline offer, device, price or schedule. To confirm availability, ask SiOnline support through the help centre, the customer care page or the support page, or call +91 91091 35959, 24 hours, 7 days.
