oneVcard vs. Lemontaps
oneVcard 91 /100 
Lemontaps 87 /100 oneVcard and Lemontaps are two German providers of digital business cards with a pronounced B2B and enterprise focus, consistent data storage in Germany and a data processing agreement (DPA) under Art. 28 GDPR; for privacy-sensitive procurement, both are therefore fundamentally credible candidates. The comparison is correspondingly close, but it comes down to three points: hosting architecture, enterprise depth and price. In the weighted overall score, oneVcard leads with 91 ahead of Lemontaps with 87.
oneVcard (oneVcard GmbH, Wörth am Main) runs its platform in an ISO/IEC 27001 certified data center in Nürnberg; hosting and development take place exclusively in Germany, with no transfer to third countries. Lemontaps (Lemon Innovation & Technology GmbH, Stuttgart) is likewise ISO/IEC 27001 certified, audited by TÜV SÜD, but hosts on AWS in the Frankfurt region. The servers are therefore located in Germany, yet they are operated by a US hyperscaler that is fundamentally subject to the US CLOUD Act. For strictly privacy-oriented buyers who prefer processing outside US-controlled infrastructure, this is the key difference in the GDPR criterion, in which oneVcard leads with 94.
In terms of feature scope, the two are close together: QR, NFC cards, Apple and Google Wallet, lead capture, a team admin console, CRM integrations (including HubSpot, Salesforce, Dynamics) and a REST API are available on both sides, as is a dedicated email signature management. On enterprise identity, oneVcard is more broadly positioned (SAML and OpenID Connect, Microsoft Entra ID, automatic user provisioning), whereas Lemontaps documents SSO so far via SAML 2.0 and shows no dedicated support for MDM. Conversely, Lemontaps brings two genuine advantages: a mature team administration with subgroups, hierarchies and field permissions, as well as solid independent user reviews (OMR 4.8/5, Trustpilot approx. 4.7/5) that oneVcard does not offer in this form. On price, oneVcard offers a permanently free Lite plan as well as a Premium plan, while Lemontaps lists a publicly viewable Pro plan.

Verdict
For the majority of German B2B users, oneVcard is the more obvious choice, which is reflected in the overall score (91 vs. 87). Three points are decisive: first, the hosting architecture; oneVcard uses an ISO 27001 certified data center in Nürnberg with hosting and development exclusively in Germany, whereas Lemontaps relies on AWS in Frankfurt (servers in Germany, but a US hyperscaler, fundamentally subject to the US CLOUD Act); second, the broader enterprise identity (SAML plus OpenID Connect, Microsoft Entra ID, automatic user provisioning and dedicated email signature management), where Lemontaps documents SSO so far only via SAML 2.0 and shows no dedicated MDM; third, the transparent pricing structure (permanently free Lite plan, publicly listed Premium plan). Both are ISO/IEC 27001 certified, provide a data processing agreement (DPA) under Art. 28 GDPR and offer German-language support, so they share the fundamental GDPR stance.
Lemontaps nevertheless remains a strong competitor, and two advantages are fair to name. First, the documented independent user reviews (OMR 4.8/5, Trustpilot approx. 4.7/5): an external validation that oneVcard cannot show in this form; anyone who places great weight on public reviews in the procurement process will find the more solid rating situation with Lemontaps (comparably strongly rated in the test field are also Blinq and HiHello). Second, the mature team administration with subgroups, hierarchies, field permissions and bulk provisioning via Excel import (up to 1,000 users), which is attractive for heavily structured corporate organizations. In short: anyone who values verified independent reviews and a particularly granular team hierarchy should seriously consider Lemontaps. Anyone seeking a functionally equivalent, price-transparent solution with a German data center, full enterprise identity (SSO/OIDC, Entra ID, provisioning) and signature management is better served by oneVcard. Team and enterprise prices should be obtained individually from both providers.
Comparison FAQ
Which provider is stronger on data protection and certification, oneVcard or Lemontaps?
Both are ISO/IEC 27001 certified, keep data in Germany and provide a data processing agreement (DPA) under Art. 28 GDPR; the fundamental GDPR stance is solid for both. The difference lies in the hosting architecture: oneVcard uses an ISO 27001 certified data center in Nürnberg, with hosting and development taking place exclusively in Germany and no transfer to third countries.
Lemontaps is ISO/IEC 27001 certified via TÜV SÜD, but hosts on AWS in the Frankfurt region: the servers are located in Germany, yet they are operated by a US hyperscaler that is fundamentally subject to the US CLOUD Act. For buyers who prefer processing outside US-controlled infrastructure, oneVcard is therefore ahead on the GDPR criterion (score 94).
How do the prices of oneVcard and Lemontaps differ?
We deliberately do not list specific prices, as they change frequently and are not transparently and completely available for all providers. With oneVcard, the Lite plan is permanently free (1 card, no payment method required), plus a Premium plan with annual or monthly billing.
With Lemontaps, the Starter plan is likewise free, and the Pro plan is publicly viewable. Team and enterprise prices are quoted by both providers only on request. It is best to request the current conditions directly from the respective provider.
Do both providers offer SSO and user provisioning for enterprise rollouts?
Yes, both offer SSO, but they differ in depth. oneVcard supports SAML and OpenID Connect (OIDC) with Microsoft Entra ID/Azure AD, Google Workspace, Okta and others, has automatic user provisioning (SCIM-like via Entra ID/HR sync) and a dedicated email signature management. Lemontaps documents SSO via SAML 2.0 (Azure/Entra ID, Okta) including SCIM provisioning and audit logs, but shows no dedicated MDM (Intune/Jamf) and so far documents no OpenID Connect.
For IT-driven rollouts with OIDC connection, oneVcard is therefore more broadly positioned.
Where does Lemontaps have genuine advantages over oneVcard?
Lemontaps brings two comprehensible strengths. First, documented independent user reviews: OMR 4.8/5 and Trustpilot approx. 4.7/5, an external validation that oneVcard does not show in this form.
Anyone who places great weight on public reviews in the procurement process will find the more solid rating situation with Lemontaps; across the entire test field, Blinq and HiHello are also similarly strongly rated. Second, a mature team administration with subgroups, hierarchies, field permissions and bulk provisioning via Excel import (up to 1,000 users), which is attractive for heavily structured corporate organizations.
On hosting (a German data center) and on OIDC, however, oneVcard is ahead.
