Probative value in banking & insurance
The probative value of an electronic signature in finance hinges on three fronts: demonstrating strong customer authentication (DSP2 SCA), proving compliance with legal deadlines (Scrivener, waiver, withdrawal), and guaranteeing contract integrity in archived form in case of ACPR/AMF audit.
Certyneo delivers for each signature an audit certificate embedded in the PDF, which aggregates technical evidence:
- Signatory identity (email + phone verified by OTP — DSP2 SCA compatible)
- Qualified timestamp of each action (sending, viewing, signing, refusal)
- SHA-256 cryptographic fingerprint of the signed document
- IP and rough geolocation of the signatory
- Detailed log of reminders and notifications
- Traceability of legal deadline (Scrivener reflection, withdrawal, waiver)
This body of evidence meets the requirements of Article 1366 of the Civil Code, the eIDAS regulation, and supervisory authorities (ACPR, AMF). In case of audit or client dispute, the audit trail constitutes direct admissible evidence.
DSP2, DDA, Monetary Code and eIDAS compliance
Certyneo operates within the legal framework applicable to banking, insurance, and fintech institutions.
DSP2 Directive (EU 2015/2366) — SCA
Strong customer authentication (SCA) requires two out of three elements: knowledge (password), possession (OTP phone), inherence (biometry). Certyneo natively covers knowledge + possession elements via OTP SMS and email.
DDA Directive (EU 2016/97) — insurance distribution
The insurance distribution directive mandates a documented pre-contractual information procedure (DIC IPID, duty of advice). Certyneo enables electronic signature of information elements with timestamped tracing of delivery to the client.
Monetary and Financial Code — art. L312-1-1 (account) & L313-14 (credit)
Article L312-1-1 mandates a written account agreement in advance; Article L313-14 governs mortgage loan offers with a 10-day reflection period. Certyneo precisely traces the moment of acceptance and expiration of the legal deadline.
Insurance Code — art. L132-5-1 & L112-2-1
Article L132-5-1 mandates a prior information note for life insurance; Article L112-2-1 sets a 14-day withdrawal period for distance selling. Certyneo''s advanced signature + qualified timestamp make these deadlines enforceable.
Frequently asked questions by financial institutions
Can a professional account agreement be electronically signed?
Yes, without restriction. Article L312-1-1 of the Monetary and Financial Code requires a prior written agreement but prescribes no specific form. Certyneo''s advanced signature (AES) meets DSP2 requirements for strong customer authentication (SCA) while precisely timestamping acceptance.
How to respect the 10-day Scrivener reflection period on a mortgage credit?
Certyneo precisely timestamps the making available of the loan offer and the client''s signature. The audit trail proves unambiguously that the 10-day period (art. L313-34 Consumer Code) was respected before signature — enforceable in case of dispute over contract unenforceability.
Does electronic signature replace manuscript notation in life insurance?
Yes, within the framework of an advanced signature (AES) with audit trail. French case law accepts that an advanced electronic signature, accompanied by an audit trail demonstrating the client''s knowledge of contractual elements, satisfies the requirements of Article L132-5-1 of the Insurance Code.
Is the 14-day withdrawal period enforceable?
Yes. The qualified timestamp of the contract signature triggers the withdrawal period under article L112-2-1 of the Insurance Code (insurance) or L222-7 of the Consumer Code (distance financial services). Certyneo tracks this period and automatically notifies its expiration.
Does Certyneo integrate with my banking CRM?
A public REST API is available with event webhooks (envelope.signed, recipient.signed, deadline.reached). Compatible with major core banking systems (Sopra, Linedata, Murex) and insurance IT systems (Adelia, Cassiopae) via webhooks or polling.
Are customer data protected by banking GDPR?
Yes. TLS 1.3 + AES-256 encryption, strict isolation by institution, 100% EU hosting (Germany) with no sub-contracting outside the EU. GDPR-compliant DPA available including clauses specific to banking secrecy (art. L511-33 Monetary and Financial Code) and insurance secrecy.
What to do in case of an ACPR or AMF audit?
The Certyneo audit trail is exportable at any time as a certified PDF. It documents the signer''s identity, qualified timestamp, document integrity, and compliance with legal deadlines. These elements are enforceable against supervisory authorities to demonstrate compliance with the duty to advise and pre-contractual information requirements.
How much does electronic signature cost for a financial institution?
A free plan allows testing on 5 envelopes per month. Beyond that, paid plans start at a rate compatible with the current opportunity cost of paper files. 10-year archiving, eIDAS audit trail, and technical support are included.
