Mobile payments face unique fraud vectors — SIM swap, device takeover, number porting, synthetic identities. Jalda combines operator-native verification, device-bound authentication, and bounded-loss architecture to make fraud structurally unprofitable.
View Security LayersSecurity failures cascade. Jalda implements multiple independent verification layers so that no single compromise can drain value.
Mobile operators maintain authoritative identity and billing relationships. Jalda leverages CAMARA Number Verification and SIM Swap Detection to verify that the person initiating payment controls the registered phone number and SIM card.
For large-value transactions, Jalda requires WebAuthn/FIDO2 biometric authentication tied to a registered device. Credentials never leave the device, and possession + biometric factors prevent remote account takeover.
Transaction limits scale with trust signals. New accounts start with low per-transaction and monthly caps. Trust increases with verified history, device consistency, and operator risk scores, limiting exposure from any single compromise.
Each layer addresses a specific attack vector. Together they create structural barriers that make fraud economically infeasible.
Before accepting payment, Jalda verifies that the user's device is connected to the mobile network with the claimed phone number. This uses GSMA's CAMARA API standard, where the operator cryptographically confirms number ownership without exposing PII.
SIM swap fraud is the primary vector for mobile account takeover. Attackers social-engineer operators to port a victim's number to a new SIM, then intercept SMS 2FA codes. Jalda queries CAMARA SIM Swap APIs to detect recent SIM changes and blocks high-risk transactions during the vulnerability window.
Legitimate users rarely change devices frequently. Jalda tracks device fingerprints (browser, OS, hardware tokens) and flags accounts that exhibit rapid device rotation, location jumps, or inconsistent behavioral patterns characteristic of account takeover or device farms.

For transactions above defined thresholds, Jalda requires FIDO2/WebAuthn biometric authentication (FaceID, TouchID, Windows Hello). Private keys never leave the secure enclave, and the protocol cryptographically binds authentication to specific devices and origins, preventing phishing and remote attacks.
Even with all verification layers, compromise is possible. Jalda implements strict per-transaction and cumulative limits that scale with account trust. If an account is compromised, exposure is capped to amounts that make fraud structurally unprofitable given attack costs.
Economics matter. If a SIM swap attack costs 200 EUR in labor and social engineering, and the maximum extractable value per account is 50 EUR, the attack is economically irrational at scale.
MNO fraud teams evaluate partners on risk posture. Jalda's architecture aligns operator incentives with security outcomes.
Operators absorb chargeback risk on DCB transactions. Jalda reduces operator exposure through defense-in-depth, limiting fraud losses that would otherwise hit operator P&L. Lower fraud = higher revenue share and sustainable partnerships.
Jalda uses GSMA CAMARA APIs (Number Verification, SIM Swap Detection, Device Swap), making integration with operator infrastructure standardized and auditable. No proprietary backdoors, no regulatory ambiguity.
Operators receive structured fraud event logs: blocked transactions, SIM swap detections, device anomalies, chargeback claims. This data improves operator fraud models and informs network-wide security policies.
Strong Customer Authentication (SCA) via WebAuthn meets PSD2 requirements. CAMARA's privacy-preserving verification architecture aligns with GDPR data minimization principles. No raw PII exposed during authentication.
For fraud teams at mobile operators or risk officers at content providers, Jalda's architecture is designed to make your second meeting easier. Let's talk specifics.
