Electronic signature in banking, insurance and fintech: complete guide

Legal framework: electronic signature in the financial sector

European directives DSP2 (payments) and DDA (insurance) impose specific requirements for strong customer authentication (SCA) and traceability of the duty to advise. Advanced signature (AES) compliant with eIDAS satisfies these requirements.

• Business account agreement: AES + DSP2 SCA (art. L312-1-1 CMF)
• Property credit: AES + timestamped Scrivener 10-day period (art. L313-14 Consumer Code)
• Life insurance subscription: AES + timestamped 14-day withdrawal period (art. L132-5-1 Insurance Code)
• DDA duty to advise: AES of the advice sheet + traceable audit trail (EU 2016/97)

Frequently asked questions — Electronic signature in banking & insurance

Does electronic signature satisfy DSP2 SCA (Strong Customer Authentication)?

Yes. DSP2 requires two of three elements: knowledge, possession, inherence. Certyneo''s advanced signature (AES) covers knowledge (password + email) + possession (OTP SMS on verified phone). SCA-compatible without additional biometrics.

How to comply with the 10-day Scrivener period on property credit?

Certyneo timestamps the receipt of the offer with a qualified timestamp under eIDAS. The 10-day period runs from that moment. The platform technically blocks all signatures before day 11 — enforceable in case of inopposability disputes (art. L313-39 Consumer Code).

Is the mandatory handwritten mention in life insurance compatible?

Yes — case law (Cass. civ. 2e, 2018) accepts that the handwritten mention required by art. L132-5-1 may be entered by keyboard, provided it is timestamped and accompanied by an advanced signature. Certyneo automatically generates the form and integrates it into the audit trail.

Is DDA duty to advise traceable?

Yes. Certyneo allows electronic signature of the advice sheet (identification of needs, rationale, product suitability). The audit trail proves delivery to the client and acceptance — enforceable before ACPR in case of audit.

How does ACPR or AMF audit proceed?

Certyneo''s audit trail is exportable at any time in certified PDF, documenting signatory identity, qualified timestamp, document integrity, compliance with legal periods. Elements are enforceable against authorities to demonstrate compliance with duty to advise and pre-contractual information.
