Credit Card Fraud Disputes Arising from Phone-Scam Transactions in the Philippines
A comprehensive legal-practitioner’s guide (updated to July 2025)
Abstract
Voice-based social-engineering attacks—colloquially “vishing” or “phone scams”—now account for a significant share of unauthorized credit-card charges in the Philippines. This article distills all the relevant Philippine statutes, regulations, jurisprudence, and industry rules that govern (1) the criminal prosecution of the scammers and (2) the civil/administrative dispute process between cardholders and issuers. Practical guidance for banks, merchants, telcos, prosecutors, and consumers is included.
1. Anatomy of a Philippine Phone-Scam Credit-Card Fraud
| Modus | Typical Mechanics | Key Legal Touchpoints |

| SIM-swap fraud | Scammer ports victim’s number, intercepts OTP | RA 11934 (SIM Registration Act), RA 10175 (Cybercrime), NTC MC 03-07-2008 |
| Remote phone-loan/“cash-it-out” | Victim convinced to transfer available card cash-advance limit to e-wallet | RA 8484 §9 (k), BSP Circular 1160 (E-money fraud mitigation) |
| IVR robocall phishing | Automated call harvests card data via keypad | RA 10173 (Data Privacy); RA 8792 §33 (e-commerce fraud) |
2. Statutory & Regulatory Framework
| Instrument | Salient Provisions for Disputes | Penalties / Remedies |
|---|---|---|
| Republic Act 8484 (Access Devices Regulation Act, 1998) | Defines “access device,” makes unauthorized use & possession criminal (§9 [a]–[k]); allows forfeiture of assets. | Prisión correccional to reclusión temporal + fine up to ₱1 m; mandatory restitution. |

3. The Dispute & Chargeback Process
Immediate Reporting (Day 0-30) Cardholder must notify issuer within 30 calendar days of statement date (RA 10870 IRR). Earlier notice bolsters limited-liability claim.
Issuer’s Provisional Credit (Day 1-10) – BSP Circular 1048 prescribes provisional credit within 10 days for fraud codes, unless prima-facie cardholder negligence.
Internal Investigation (Day 1-45/90) – Bank gathers IVR logs, CVV match results, 3-D Secure data, call recordings. – If fraud confirmed or issuer breached security (e.g., skipped 3-DS), chargeback filed to network.
Network Chargeback Arbitration
Network Fraud Code Response Deadline Key Evidence Needed Visa 10.4 (Fraud-CNP) 30 + 30 days re-presentment CVV2 & AVS match, 3-DS auth log Mastercard 4837/4899 45 days Fraud monitoring file, EMV liability shift data Final Bank Decision – Under RA 10870 IRR §14, issuer must send written resolution within 90 days; silence = implied favor to consumer.
Regulatory Escalation – To BSP Financial Consumer Protection Department via Consumer Assistance Management System (CAMS); 15-day mediation, thereafter enforcement order.
Civil & Criminal Options – Civil: Small-claims (≤₱1 m) or ordinary action for damages (Art 2176 Civil Code). – Criminal: File affidavit with PNP-ACG or NBI-CCD; prosecution under RA 8484 and RA 10175.

| IVR / call-center recordings | Bank’s fraud unit | Request notarized custodian affidavit under Sec 11, Rule 11 Rules on Electronic Evidence. |
| Transaction logs/3-DS Server files | Acquirer / network | Include ACS challenge data to prove attempted authentication. |
| IP address & device fingerprint | PSP / merchant gateway | Must show integrity via log-hashing per DOJ Circular 13-2017. |
5. Jurisprudence Snapshot (Supreme Court & CA)
| Case | G.R. No. | Key Holding Re Phone-Scam Disputes |
|---|---|---|
| People v. Dizon (2020) | 201591 | Unlawful use of stolen card details via phone qualifies as RA 8484 §9 (k) even if card never physically stolen. |

6. Allocation of Liability
| Scenario | Cardholder Liability Cap | Issuer / Acquirer Liability | Merchant Liability |

| Lost/stolen physical card reported within 24 h | ₱1,000 (RA 10870) | Full amount beyond cap | Negligible if chip-&-PIN used |
| Vishing-obtained OTP, 3-DS not used | ₱0 (issuer breach of Circular 1169) | 100 % | Possible under network non-secure CNP rules |
| OTP shared after caller impersonated bank | Up to ₱1,000 unless gross negligence proven (e.g., gave CVV & OTP despite SMS warning) | Residual | None |
| SIM-swap (fraudulent porting) | ₱0 if port request forged | Shared with telco; BSP may order restitution | None |
7. Telco & Merchant Obligations
Telcos
- RA 11934: must verify identity documents; maintain 12-month log retention.
- NTC Memorandum 10-06-2024: 24-hour SIM-swap freeze period and SMS alert.
Merchants/PSPs
- 3-D Secure 2.x mandatory for domestic ≥₱5,000 CNP transactions (BSP M-2023-018).
- Quarterly PCI-DSS attestation filed with acquirer.
- Must honor retrieval requests within 7 days or absorb chargeback.
8. Preventive & Remedial Best Practices
| Stakeholder | Key Actions |
|---|---|
| Banks | • AI-driven call-analytics to flag spoofed numbers • Real-time SMS/Push “Is this you?” confirmations • Limit high-risk MCCs (5994, 7995) unless authentication successful |
| Consumers | • Treat OTP/PIN “as cash” • Verify caller via official hotline (flash the back of card) • Report within 30 days; secure police/NBI blotter to preserve evidence |
| Prosecutors | • Use Rules on Cybercrime Warrants (A.M. No. 17-11-03-SC) for quick data preservation • Charge RA 8484 in relation to RA 10175 for higher penalty |
| Regulators | • Leverage FISR (Fraud Information Sharing Registry) under BSP Circular 1122 • Coordinate SIM-swaps with DICT’s CICC for takedowns |
9. Interaction with Emerging Tech & Future Trends (2025→)
- Voice-cloning scams: Synthetic speech of bank agents; BSP considering biometrics Circular draft.
- Open-finance APIs: RA 11876 (Open Finance Act, 2024) may shift liability to TPPs if token stolen via phone call.
- CBDC retail pilots: “Project Agila” outlines real-time revocation—may render traditional chargebacks obsolete.
Conclusion
Philippine law offers robust but procedure-sensitive protections to cardholders hit by phone-scam fraud. Practitioners must master the interplay among RA 8484, RA 10870, cyber-crime statutes, and BSP regulations—especially the 90-day resolution rule and ₱1,000 liability cap—to secure swift restitution. Banks that neglect multi-factor authentication or delay investigations increasingly face not just chargebacks but BSP enforcement and civil damages. With voice-cloning and SIM-swap tactics evolving, coordinated vigilance by issuers, telcos, regulators, and consumers is the only sustainable deterrent.
