A POS payment involves more than inserting a card and waiting for a receipt. This guide explains the roles of the customer, agent or merchant, terminal provider, issuing bank and payment network from authorization through settlement. It shows what to check before entering a PIN, how to read Approved, Declined, Failed and Pending responses, and why a printed slip alone
POS does not use one customer USSD code. The terminal processes card/payment requests, while disputes use bank or provider support.
What to dial first
| Need | Code or route | Use it for |
|---|---|---|
| POS terminal | Merchant/agent terminal | Start card payment or withdrawal |
| Customer bank | Official bank support | Report debit without value |
| Terminal provider | Provider support line/app | Resolve settlement or terminal errors |
Step-by-step
- Merchant enters the amount on the POS.
- Customer confirms amount and inserts/taps card.
- Customer enters PIN privately if required.
- Wait for approved, declined or failed status.
- Print/save receipt.
- Release value only after approved/confirmed payment.
Expected result
Approved should produce terminal confirmation and receipt. Failed or pending needs evidence.
Alternatives
Use transfer, wallet or cash if POS is unavailable.
Common errors and fixes
- Issuer unavailable: retry later if no debit.
- Failed but debited: keep slip and report.
- No settlement: merchant contacts terminal provider.
Customers should shield PINs; agents should keep transaction records.
POS payment in plain English
A POS payment happens when a customer uses a card or payment method on a terminal, the terminal sends the request through payment networks, the bank approves or declines it, and the merchant receives a receipt and later settlement. If any part fails, evidence is needed.
Why POS is everywhere
POS terminals are common in shops, fuel stations, pharmacies, markets and agent banking stands. They help people pay without cash and help agents provide withdrawal or transfer services.
Because POS involves cards, banks, terminals, networks and settlement accounts, a transaction can fail even when a customer is debited. Understanding the flow helps both customers and merchants respond calmly.
Who is involved in a POS transaction
The customer, merchant or agent, POS terminal provider, acquiring bank, issuing bank and payment switch may all be part of the process. The customer sees only the terminal, but the transaction travels through several systems.
A receipt matters because it carries transaction details. Merchants should keep daily records, and customers should keep failed receipts until disputes are resolved.
What happens during payment
A typical POS card payment follows these stages.
- Customer presents card or payment method.
- Merchant enters amount and initiates transaction.
- Terminal requests authorization from the banking network.
- Customer enters PIN where required.
- Issuing bank approves or declines.
- Terminal prints or displays receipt.
- Merchant reconciles transaction and waits for settlement.
If the terminal says failed but the customer is debited, both sides should keep evidence and follow dispute processes.
POS status messages explained
| Status | Meaning | Customer action | Merchant action |
|---|---|---|---|
| Approved | Bank authorized payment | Keep receipt | Release goods after value policy |
| Declined | Bank refused request | Use another method | Do not release goods |
| Failed | Request did not complete | Check debit alert | Keep slip and reconcile |
| Pending | Status unclear | Wait and verify | Do not rely on screenshot only |
Three POS situations
The following examples explain three POS situations and show how the guidance applies in different situations.
1. Approved purchase in a pharmacy
The POS prints approved and the merchant sees the sale in terminal history. The customer keeps the receipt and leaves with goods.
2. Failed withdrawal at an agent
The terminal prints failed but the customer receives a debit. The agent should not pay cash without confirmation, and the customer should report with the slip.
3. End-of-day reconciliation
A shop owner compares receipts, bank settlement and sales records. This helps catch missing settlement early.
POS safety for customers and agents
Customers should shield card PINs and avoid giving cards to strangers out of sight. Agents should not rely only on customer screenshots for payment confirmation.
For formal disputes, use the bank, terminal provider or payment processor official support route. Keep transaction IDs, amounts and dates.
POS payment FAQs
The following examples explain pOS payment FAQs and show how the guidance applies in different situations.
Why was I debited when POS failed?
The authorization may have reached your bank while the terminal did not receive final confirmation. Report with evidence.
Should the agent give cash after a failed withdrawal?
Only after confirming value through proper records. Failed slips need dispute handling.
How long does settlement take?
Timelines vary by provider and bank. Merchants should confirm with their provider.
Is a screenshot proof of payment?
It is not enough by itself. Confirm through account or terminal records.
POS works best with records
POS payments are useful, but records protect everyone. Receipts, terminal history and settlement checks reduce arguments.

Payment-system reference
The CBN payment-modes page places POS within Nigeria’s non-cash retail channels. A merchant must still rely on the acquiring bank or licensed provider for the status and settlement of a particular terminal transaction.
