Since the new **NPCI 2-Factor Authentication (2FA)** merchant login rules came into effect, I frequently get: > **Error 55: Merchant Aadhaar Biometric Mismatch / Device Authentication Failed** Setup details: - Device: **Mantra MFS100** - OS: Windows 10 Due to this, my AePS terminal remains locked for the **entire day**. Has anyone found a permanent fix?

## L0 vs L1 Biometric Device Architecture | Feature | L0 (e.g. MFS100, Morpho E3) | L1 (e.g. MFS110, Morpho L1) | |---------|------------------------------|-------------------------------| | Encryption location | Host OS (Windows driver) | On-device hardware crypto chip | | Vulnerability | Memory replay / spoofing attacks possible | Cryptographic signing happens inside scanner | | NPCI AePS status | Being phased out | **Mandatory from April 2024** | ### Why L1 is more secure In **L0 devices**, fingerprint image encryption happens at the OS level, leaving a theoretical window for memory replay attacks. In **L1 devices**, the dedicated hardware cryptographic processor inside the scanner signs and encrypts data *before* it ever reaches the host computer. > All AePS applications now enforce L1 device whitelist validation at the NPCI switch level.
