oneVcard vs. Linq
oneVcard 92 /100 
Linq 59 /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, offering NFC cards, a lead scanner, and strong user reviews. In 2025/2026, however, the company realigned its strategy.
Following a USD 20 million Series A round, Linq has shifted its focus significantly toward AI messaging infrastructure, while several market sources indicate that the original business card and NFC product is now largely discontinued or has an uncertain future. This is exactly where our comparison comes in: we put the German enterprise solution oneVcard, hosted exclusively in Germany, up against Linq, an internationally recognized provider whose core product is strategically fragile, with a focus on GDPR, future-proofing, team administration, and integrations.
After all, 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 in question.

Verdict
Overall, oneVcard clearly comes out ahead with 92 out of 100 points, well above Linq (59 out of 100). Three factors are decisive: First, the level of data protection. oneVcard hosts and develops exclusively in Germany, in its own ISO 27001-certified data center in Nuremberg, with a data processing agreement (DPA) under Art. 28 GDPR, an external data protection officer, 2FA, and regular penetration tests, without any transfer to third countries.
Linq, by contrast, hosts in the USA; for EU customers, this means a GDPR third-country transfer that is only safeguarded through 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 its core business card product into question, while oneVcard remains specialized in exactly that.
Third, enterprise depth: oneVcard offers SSO (SAML 2.0, Microsoft Entra ID, Google Workspace), automatic user provisioning, MDM rollout via Intune/Entra, Apple and Google Wallet, dedicated email signature management, and more than 20 integrations (including SAP, Personio, BambooHR, Salesforce, and HubSpot), features that with Linq are either undocumented or not available (such as Apple/Google Wallet). To be fair, it should be noted that Linq is ahead in independent user reviews (G2 rating around 4.8/5 from about 553 reviews), and its 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 nevertheless the clearly more viable choice.
Comparison FAQ
Is oneVcard more GDPR-compliant than Linq?
Yes, significantly. oneVcard is hosted and developed exclusively in Germany, in its own ISO 27001-certified data center in Nuremberg, with a data processing agreement (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 only safeguarded through EU Standard Contractual Clauses (SCCs). While Linq is SOC 2 Type II certified and provides a DPA, from a German compliance perspective it does not reach the level of hosting purely in Germany.
Why is Linq considered a strategic risk for digital business cards?
In 2025/2026, Linq realigned itself strongly toward AI messaging infrastructure and raised a USD 20 million Series A round in February 2026 for this purpose. According to several market sources, the original business card and NFC product has since been considered largely discontinued or with an uncertain future.
Anyone rolling out a digital business card platform company-wide is making a multi-year decision, and 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 any advantages over oneVcard?
Yes, in two areas. In independent user reviews, Linq is ahead: around 4.8/5 on G2 from about 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.
However, for GDPR-sensitive companies, these strengths do not outweigh the lack of an EU server location, the strategic product risk, and the features that are unclear in the enterprise context (SSO/SCIM/MDM not documented, no Apple/Google Wallet).
Which enterprise features does oneVcard offer that Linq lacks or leaves unclear?
oneVcard offers SSO via SAML 2.0, Microsoft Entra ID/Azure AD, and Google Workspace, automatic user provisioning, as well as MDM rollout via Microsoft Intune/Entra, for example for Wallet and app distribution. Added to this are Apple and Google Wallet passes, dedicated email signature management with a certified Outlook add-in, and more than 20 integrations, including SAP, Personio, BambooHR, Salesforce, and HubSpot.
With Linq, core enterprise identity features (SAML/OIDC SSO, SCIM provisioning, MDM with Intune/Jamf) are not publicly documented; Apple/Google Wallet and email signature management are missing or unconfirmed, and prices are listed exclusively in USD.
