Frequently Asked Questions

Q: Does this work when a user is roaming?

Yes. If we have coverage of the user’s home network, the service works worldwide because the mobile IP address checked is supplied by their home Mobile Network Operator (MNO), which owns the SIM card.

Q: How do you handle Dual SIM phones?

If two SIM cards are present, IDlayr SNA verifies only the SIM that is connected or enabled for mobile data.

Q: Can you prevent SIM Swap fraud?

Yes. IDlayr can check for a recent change of SIM card, indicating potential fraud. With this signal you can reject an authentication request or route the user through a higher-friction step-up check.

Q: Do IDlayr solutions work over WiFi?

Yes. IDlayr can silently switch the mobile identity authentication check to run over the mobile data channel, even if the phone is connected via WiFi.

Q: Do you offer demo / testing environments?

Yes. We offer a Demo & Testing Environment with demo apps, sandbox tools, live testing environments, and professional services to help you learn, demo, adopt, and deploy mobile identity technology quickly.

Q: What kind of fallback solutions do you offer, if Silent Network Authentication is unavailable?

IDlayr Reverse SMS provides a high-security, low-friction fallback for SNA that works wherever your users are and strengthens your overall security posture.

Q: How does your solution help with payments?

SCA-compliant payment authentication can be achieved by combining silent possession-factor verification with a biometric to deliver secure, low-friction step-up or payment authentication—reducing checkout delay and improving user experience and conversion rates.

How can you help protect against AI Fraud?

AI cannot fake possession factors. Using the cryptographically secure SIM card as a possession-factor is a very effective method for preventing remote, AI-based, attacks. The binding between the SIM card and the mobile number creates a secure digital identity that provides a foundational trust layer for mobile identity and any associated credentials.
