oneVcard vs. Blinq
oneVcard 92 /100 
Blinq 75 /100 oneVcard and Blinq both rank among the leading platforms for digital business cards, yet they target very different buyers. Blinq is an Australian provider founded in Melbourne in 2017, with more than 2.5 million users, broad Fortune 500 adoption, and exceptionally strong user reviews (G2 4.8 from over 8,800 reviews, Capterra 4.9). The product is mature, easy to use, and comes with a complete enterprise feature set: enforced SSO (SAML, Okta, Azure AD), SCIM provisioning, more than 20 CRM integrations, analytics, lead capture, NFC cards, plus Apple and Google Wallet.
oneVcard is the German challenger from oneVcard GmbH, and it plays to its strengths precisely where Blinq is structurally vulnerable: GDPR compliance and operation within Germany. oneVcard hosts and develops exclusively in Germany, operates its own ISO 27001-certified data center in Nuremberg, provides a data processing agreement (DPA) under Art. 28 GDPR on request, has an external data protection officer (Prof. Dr. Eberhard Schott), and commissions regular penetration tests. On the enterprise side, oneVcard offers SAML 2.0, Microsoft Entra ID and Google Workspace, automatic user provisioning, MDM rollout via Microsoft Intune/Entra, more than 20 integrations (including SAP, Personio, BambooHR, Salesforce, HubSpot), as well as dedicated email signature management with a certified Outlook add-in. In our overall rating, oneVcard leads with 92 out of 100 points, ahead of Blinq with 75.

Verdict
For German and EU companies we recommend oneVcard, especially when data protection, legal certainty, and Microsoft integration are priorities. The decisive difference lies in data residency: Blinq hosts on the Google Cloud Platform, and according to its privacy policy personal data may be processed in the USA, among other locations; transfers outside the EEA are safeguarded via Standard Contractual Clauses, and the controller is based in Australia.
A DPA is not publicly available from Blinq (trust center documents only on request), the ISO 27001 certification is held by the cloud provider Google, not by Blinq itself, and German-language support is not documented. oneVcard, by contrast, hosts and develops exclusively in Germany, operates its own ISO 27001 data center in Nuremberg with no transfer to third countries, and provides a DPA, an external data protection officer, and German-language support. That is why oneVcard leads both the overall rating (92 to 75) and the GDPR category alone (94/100).
When it comes to the functional IT rollout, the two are on par: both offer SSO and automatic provisioning, while oneVcard additionally adds MDM via Microsoft Intune/Entra and standalone email signature management, which Blinq does not cover to this depth. In fairness, it should be noted where Blinq has genuine advantages: in independent user reviews Blinq clearly leads with G2 4.8 (over 8,800 reviews) and Capterra 4.9, the product is very broadly proven internationally, and it is a mature choice for globally distributed teams.
Anyone working primarily outside the EU, or who weights maximum market penetration and review density more heavily than German data residency, can do well with Blinq. For the German B2B mid-market and all GDPR-sensitive organizations, however, oneVcard is the more suitable platform.
Comparison FAQ
Where is my data hosted - with oneVcard or with Blinq?
This is the most important difference. oneVcard hosts and develops exclusively in Germany and operates its own ISO 27001-certified data center in Nuremberg for this purpose, with no transfer to third countries. Blinq hosts on the Google Cloud Platform; according to its privacy policy, personal data may be processed in the USA, Canada, Germany, Ireland, Belgium, and Finland, among other locations, with transfers outside the EEA safeguarded via Standard Contractual Clauses.
The controller is based in Australia. For GDPR-sensitive German companies, oneVcard's purely German data storage is therefore a clear advantage.
Are both providers GDPR-compliant, and is there a DPA?
Blinq declares GDPR compliance and is SOC 2 Type II certified (via Vanta, with an annual third-party audit). A data processing agreement (DPA) under Art. 28 GDPR is not publicly available from Blinq, however - the documents in the trust center are only accessible on request - and the ISO 27001 certification is held by the cloud provider Google, not by Blinq itself. oneVcard provides a data processing agreement (DPA) under Art. 28 GDPR on request, holds its own ISO 27001 certification, has an external data protection officer (Prof. Dr. Eberhard Schott), daily backups, 2FA, and regular penetration tests.
In the GDPR category alone, oneVcard leads with 94 out of 100 points.
Which provider is better suited for a company-wide IT rollout with SSO?
Both are strongly positioned here. Blinq offers enforced SSO (SAML, Okta, Azure AD) and SCIM provisioning via Okta and Entra for automated on- and offboarding. oneVcard likewise offers SAML 2.0 as well as Microsoft Entra ID/Azure AD and Google Workspace with automatic user provisioning.
The difference lies in the detail: oneVcard additionally supports MDM rollout via Microsoft Intune/Entra (e.g., wallet and app distribution) and dedicated email signature management with a certified Outlook add-in - areas that Blinq does not cover to this depth. Both come with more than 20 integrations and a REST API.
Does Blinq also have advantages over oneVcard?
Yes. Blinq scores above all in independent user reviews: G2 4.8 from over 8,800 reviews, Capterra 4.9, and Trustpilot around 4.7 rank among the best in the industry. With more than 2.5 million users and broad Fortune 500 adoption, the product is very mature internationally and easy to use.
For globally distributed teams that weight maximum market penetration and review density more heavily than German data residency, Blinq is a solid choice. For the German B2B market and GDPR-sensitive organizations, however, oneVcard's purely German data storage, its DPA, and its German-language support are the deciding factors.
