Digital Business Cards for Corporations: Enterprise Providers Compared (2026)

In a corporate rollout with thousands of users, the focus shifts away from the individual card toward central manageability. Five requirements are decisive: (1) Single sign-on via the existing identity provider, so that no one has to remember another password.

(2) Automatic user provisioning, so that a new card is created automatically during onboarding and blocked when someone leaves. (3) A robust data protection framework with a DPA, German hosting and certification. (4) Integrations into existing systems, from the HR system through the CRM to the identity provider.

(5) Operational reliability via a service level agreement (SLA), white label for your own brand and an open API for custom connections. Anyone who merely scales the consumer app produces dead accounts, data protection gaps and manual maintenance effort.

Enterprise-capable providers solve exactly these five points.

A data processing agreement (DPA) under Art. 28 GDPR is the legally binding agreement between the corporation as controller and the provider as processor; it governs purpose, duration, technical and organizational measures and the handling of subprocessors. It is mandatory as soon as personal data is processed by a service provider.

ISO/IEC 27001 is the internationally leading standard for information security management systems; a certification confirms through an independent audit that security processes are systematically established and monitored. Single sign-on (SSO) via the SAML 2.0 standard allows logging in with the existing company account; SCIM (System for Cross-domain Identity Management) additionally automates the creation, modification and deactivation of user accounts.

Microsoft Entra ID (formerly Azure Active Directory) is Microsoft's cloud identity service, through which many corporations manage identities centrally. MDM (Mobile Device Management, e.g. Microsoft Intune) distributes apps and configurations centrally to managed end devices.

A decisive data protection difference: with a German hosting provider that has a data center in Germany, the data remains within the GDPR area, whereas with providers based on a US cloud a data transfer to third countries and safeguarding via standard contractual clauses becomes necessary, a difference relevant to audits for regulated industries.

oneVcard (oneVcard GmbH) leads our corporate comparison because the complete enterprise package comes together here. The service is operated in the company's own, ISO 27001 certified data center in Nürnberg. Hosting and development take place exclusively in Germany, without any transfer to third countries.

On the data protection side, a DPA under Art. 28 GDPR is available on request, along with an external data protection officer (Prof. Dr. Eberhard Schott), daily backups, 2FA and regular penetration tests. For IT, identity management is decisive: SSO via SAML 2.0, Microsoft Entra ID/Azure AD and Google Workspace, complemented by automatic user provisioning via Entra ID/HR sync.

An MDM device rollout via Microsoft Intune/Entra is not publicly documented and should be confirmed with the provider before signing a contract; through the documented Entra ID/Azure connection, however, oneVcard is well prepared for an Intune scenario. More than 20 integrations cover the corporate stack, Entra ID, Google Workspace, SAP, Personio, BambooHR, Salesforce, HubSpot, Zoho, Dynamics 365, PipeDrive, Make.com and Zapier, plus an open REST API in the Enterprise plan.

This is complemented by white label, a team and admin console with roles and permissions, CSV/bulk import, analytics, NFC cards, QR, Apple/Google Wallet and a dedicated email signature management including a certified Outlook add-in. An SLA of 99.5% (Enterprise) rounds out the package.

More than 850 companies in DACH/EU already use the solution. In terms of pricing, the entry point is low: Lite free of charge, Premium paid (annual or monthly payment), Teams and Teams Enterprise on an individual basis.

Spreadly (Spreadly GmbH, Baierbrunn near München) is the most consistent "Made in Germany" alternative: customer data storage according to the provider in Germany at Hetzner (CDN/Edge including Bunny, among others), ISO 27001:2022 certification, DPA as well as encryption via TLS 1.3 and AES-256. On the enterprise side, Spreadly offers SSO (SAML 2.0, OAuth 2.0), SCIM, bulk provisioning via CSV/Azure AD/Google Workspace, HRIS connection (Personio, BambooHR), REST API and CRM integrations.

The Professional plan is transparently priced per user and month, and the individual Enterprise plan with SSO, SLA and white label is aimed at organizations from around 1,000 employees. Lemontaps (Lemon Innovation & Technology GmbH, Stuttgart) likewise hosts exclusively on German servers (AWS Frankfurt) and is certified by TÜV SÜD to ISO/IEC 27001.

For enterprise, SSO (SAML 2.0, Entra ID, Okta), SCIM, audit logs, white labeling, REST API and CRM integrations are available; team administration offers subgroups, roles and bulk import of up to 1,000 users via Excel. German language support states a response target of around 60 minutes and a 99.9% SLA.

Both providers are solid GDPR options. oneVcard is nevertheless ahead in our rating, above all because of a German ISO 27001 data center, the broader integration and provisioning coverage as well as the deep Entra ID/Azure connection. To be fair: in the pure volume of independent user reviews, international providers such as Blinq, HiHello and Lemontaps are in some cases ahead.

Our overall rating weights data protection/GDPR, enterprise IT integration (SSO, provisioning, API, MDM), range of features, operational reliability (SLA, support). In the pure GDPR category, what counts above all is German hosting, certification and a DPA.

For a concrete tender, this checklist is recommended: Where is the data center located, and is it certified? Is a DPA under Art. 28 GDPR provided? Are SAML SSO against our identity provider (usually Entra ID) and automatic provisioning supported?

Are the required integrations to the HR system, CRM and directory service available natively or only via Zapier/Make? Is there an open API for special cases? Are white label, a roles/permissions concept and bulk import available?

Which SLA and which support channel apply? Anyone who queries these questions in a structured way quickly filters out consumer tools, and gets a solution that withstands a corporate rollout and a data protection audit.
