oneVcard vs. Linq
oneVcard 91 /100 
Linq 62 /100 Linq was long one of the best-known names in the digital business card market, a US provider from Birmingham (Alabama), founded in 2019, with NFC cards, a lead scanner and strong user ratings. In 2025/2026, however, the company strategically repositioned itself: after a Series A financing round of USD 20 million, Linq is shifting its focus significantly toward AI messaging infrastructure, while, according to several market sources, the original business card and NFC product is considered largely discontinued or of uncertain future.
This is exactly where this comparison comes in: we set the German, exclusively Germany-hosted enterprise solution oneVcard against the internationally known but, in its core product, strategically fragile provider Linq, with an emphasis on GDPR, future-proofing, team management and integrations. Because anyone rolling out a digital business card platform today is making a multi-year infrastructure decision and does not want to bet on a product whose continued existence is uncertain.

Verdict
In the overall result, oneVcard clearly leads Linq with 91 out of 100 points (62 out of 100). Three points are decisive: First, the level of data protection; oneVcard hosts and develops exclusively in Germany, in an ISO 27001 certified data center in Nuremberg, with a DPA under Art. 28 GDPR, an external data protection officer, 2FA and regular penetration tests, without any third-country transfer.
Linq, by contrast, hosts in the USA; for EU customers this means a GDPR third-country transfer that is safeguarded only via EU Standard Contractual Clauses, despite the existing SOC 2 Type II certification and DPA. Second, future-proofing: Linq's pivot to AI messaging infrastructure calls the business card core product into question, while oneVcard remains specialized precisely in that.
Third, enterprise depth: oneVcard offers SSO (SAML 2.0, Microsoft Entra ID, Google Workspace), automatic user provisioning, Apple and Google Wallet, a dedicated email signature management as well as more than 20 integrations (including SAP, Personio, BambooHR, Salesforce, HubSpot), features that with Linq are partly not documented and partly not available (such as Apple/Google Wallet). In fairness it should be noted: in independent user ratings Linq is ahead (G2 around 4.8/5 from roughly 553 reviews), and the direct CRM integrations with Salesforce and HubSpot are strong for sales.
For German and EU companies that prioritize data protection, planning security and enterprise integration, oneVcard is nonetheless the clearly more viable choice.
Comparison FAQ
Is oneVcard more GDPR-compliant than Linq?
Yes, clearly. oneVcard is hosted and developed exclusively in Germany in an ISO 27001 certified data center in Nuremberg, with a DPA under Art. 28 GDPR, an external data protection officer, daily backups, 2FA and regular penetration tests, without any transfer to third countries. Linq, by contrast, hosts in the USA.
For EU customers this creates a GDPR third-country transfer that is safeguarded only via EU Standard Contractual Clauses (SCC). Linq is indeed SOC 2 Type II certified and provides a DPA, but from the perspective of German compliance it does not reach the level of purely German hosting.
Why is Linq considered a strategic risk for digital business cards?
In 2025/2026, Linq strongly repositioned itself toward AI messaging infrastructure and raised a Series A round of USD 20 million for this in February 2026. According to several market sources, the original business card and NFC product has since been considered largely discontinued or of uncertain future.
Anyone rolling out a digital business card platform company-wide is making a multi-year decision; a provider whose core product is strategically in question is risky for that. oneVcard remains specialized in digital business cards and offers greater planning security here.
Does Linq have advantages over oneVcard in anything?
Yes, in two areas. In independent user ratings Linq is ahead, on G2 around 4.8/5 from roughly 553 reviews, plus very good app store ratings. And Linq offers established direct CRM integrations with Salesforce and HubSpot as well as an API, which is attractive for sales-oriented teams.
For GDPR-sensitive companies, however, these strengths do not outweigh the missing EU hosting location, the strategic product risk and the functions that are unclear in the enterprise environment (SSO/SCIM/MDM not documented, no Apple/Google Wallet).
Which enterprise features does oneVcard offer that Linq lacks or that are unclear?
oneVcard offers SSO via SAML 2.0, Microsoft Entra ID/Azure ID and Google Workspace, automatic user provisioning. Added to this are Apple and Google Wallet passes, a dedicated email signature management with a certified Outlook add-in and more than 20 integrations, including SAP, Personio, BambooHR, Salesforce and HubSpot.
With Linq, central enterprise identity functions (SAML/OIDC SSO, SCIM provisioning, MDM with Intune/Jamf) are not publicly documented; Apple/Google Wallet and an email signature management are missing or not confirmed, and prices are listed exclusively in USD.
