THE CONTUM APPROACH
We deliver working business processes, not isolated technologies.
Electronic signatures create real value when identity, document generation, validation and preservation all fit the organisation’s operating model.
We stay involved from business and technical design through integration to post-launch support.
Digital identity and EUDI Wallet
We connect online onboarding to business systems, from data collection through identification and checks to contracting. Our DÁP eIdentification component is ready, and we design EUDI Wallet (European Digital Identity Wallet) acceptance and attestation-issuance integrations.
Enterprise Content Management
We have worked in enterprise document management since 2004. We design, implement and support IBM FileNet environments and connect digital documents to signing and preservation workflows.

CURRENT FOCUS
Preparing for the next digital identity environment.
eIDAS 2.0, the EUDI Wallet, AMLR and DÁP bring new opportunities and new responsibilities. Beyond connectivity, organisations must design data requests, validation, business use and evidence retention.
Identity
EUDI Wallet, DÁP or another suitable identity route
Data and checks
Receive, validate and interpret the required data in the business context
Contract preparation
Prepare the documents for signing once the required business decisions and approvals are in place.
Electronic signature
Embed the appropriate signing method in the same customer journey
Consulting and solution design
Joint design of the business process, regulatory model, system boundaries and target architecture.
Custom delivery and systems integration
Development, configuration, adapters, APIs, migration, testing and production rollout.
Support and continuous improvement
Operational support, release management, incident resolution and delivery of new business requirements.
Managed services
Monitoring and operation of selected solution components under clearly defined responsibilities.
LONG-TERM TRUSTED ARCHIVING
Storage alone does not keep a signature verifiable over time.
The preservation solution manages the document together with the validation data, timestamps and renewal events required for future verification.
