POS Fraud Safety
Avoid POS fraud and card skimming with disciplined device checks, transaction hygiene, reconciliation, and dispute readiness. Merchants and customers both play crucial roles.
Device Hygiene
1
- Inspect POS terminals for overlays, loose parts, or unusual attachments that hide skimming hardware.
- Ensure firmware is updated and sourced from the official provider. Avoid unknown maintenance technicians.
Transaction Safety
2
- Keep cards within sight and avoid handing them out of view. Verify the amount before approving.
- Use chip and PIN where available; avoid magstripe-only transactions which are easier to skim.
- Enable transaction alerts and review statements frequently for anomalies.
Reconciliation and Disputes
3
- Maintain daily reconciliation logs and cross‑check terminal batch totals with bank deposits.
- For unauthorized debits, contact the acquiring bank, provide terminal IDs, transaction timestamps, and receipts.
- Document CCTV footage and staff rosters for investigative audits.
Customer Habits
4
- Shield PIN entry and avoid distractions during transactions.
- Decline assistance from unknown bystanders; verify staff uniforms and IDs.
Merchant Policies
5
- Define terminal custody, maintenance logs, and access control to prevent tampering.
- Train staff to recognize overlays and report anomalies immediately.
Evidence Retention
6
- Archive receipt copies, batch reports, and error logs for at least 6–12 months.
- Retain surveillance snapshots tied to suspect transactions for investigators.
Dispute Process
7
- Follow acquiring bank dispute timelines and provide complete documentation to avoid rejections.
- Escalate unresolved disputes with case references and chronological evidence.
Checklist
Work through these steps in order.
- Inspect terminals regularly.
- Use chip/PIN; verify amounts.
- Enable alerts; reconcile daily.
- Escalate with full transaction data.
