oneVcard vs. My Digital Card (MDC)
oneVcard 91 /100 
My Digital Card (MDC) 49 /100 oneVcard and My Digital Card (MDC, operator: Relativity GmbH, Berlin) pursue two fundamentally different approaches to digital business cards. oneVcard is a software-centric B2B platform: hosting and development take place exclusively in Germany, operated in an ISO 27001 certified data center in Nürnberg, complemented by enterprise identity features such as SSO (SAML, Entra ID, Google), automated user provisioning, and a dedicated email signature management for Outlook. My Digital Card comes from the hardware corner: at its core are high-quality NFC cards made of metal or wood as a one-time purchase, which include the cloud-based profile platform "MDC-Cloud" free of charge.
Technically, however, this cloud is implemented as a no-code application on the US platform Bubble.io and is delivered via Cloudflare. This makes MDC attractive for anyone primarily looking for a first-class physical card, but it raises questions for privacy-critical B2B deployments.
This comparison assesses both providers objectively and names the strengths as well as the weaknesses of both sides.

Verdict
In the B2B comparison, oneVcard leads clearly (overall score 91 vs. 49), primarily because it covers the typical requirements of larger organizations that My Digital Card does not aim to compete on. The decisive difference lies in the hosting: oneVcard operates data and development exclusively in Germany in an ISO 27001 data center in Nürnberg and provides a data processing agreement pursuant to Art. 28 GDPR.
With My Digital Card, the operator is indeed a German GmbH based in Berlin, but the actual MDC-Cloud runs on the US no-code platform Bubble.io (standard hosting on AWS in the USA); a German or EU server location, a data processing agreement, ISO 27001 or SOC 2 are not documented, a real GDPR risk for companies. When it comes to enterprise administration (SSO, provisioning), integrations (20+ plus REST API), and email signature management, oneVcard is also considerably more broadly positioned, while MDC offers no verifiable features here.
To be fair, it should be noted: My Digital Card plays to its strength elsewhere. The high-quality NFC metal and wood cards are a genuine unique selling point compared to pure software providers, the free cloud included in the card price avoids an additional monthly subscription, and a company dashboard with white-label option, success tracking, and volume discounts exists.
For individual users or small teams who primarily want an elegant physical card plus a simple online profile, MDC can therefore be a good fit. Those who, by contrast, want to roll out digital business cards across the enterprise, manage them centrally, and host them in Germany in a GDPR-compliant manner are better served by oneVcard.
An honest note on oneVcard: so far there are hardly any independent user reviews (for example on G2, Capterra, or Trustpilot), but such public reviews are equally lacking for My Digital Card.
Comparison FAQ
Where is the data of oneVcard and My Digital Card hosted?
oneVcard hosts and develops exclusively in Germany and hosts in an ISO 27001 certified data center in Nürnberg; a data processing agreement pursuant to Art. 28 GDPR is provided. With My Digital Card, the operator is indeed a German GmbH (Relativity GmbH, Berlin), but the MDC-Cloud itself technically runs on the US no-code platform Bubble.io and is delivered via Cloudflare.
A German or EU server location, a data processing agreement, as well as ISO 27001 or SOC 2 are not documented for My Digital Card, a point that should be examined for privacy-sensitive B2B deployments.
Which enterprise features does oneVcard offer that My Digital Card lacks?
oneVcard supports single sign-on (SAML, Entra ID, Google), automated user provisioning, and a dedicated email signature management for Outlook, and comes with over 20 integrations including a REST API. With My Digital Card, SSO, MDM, a public API, or named CRM integrations cannot be verified; there is a company dashboard with white label, success tracking, and volume discounts, but it turns out rather lightweight and does not replace a full-fledged enterprise administration.
What is My Digital Card the better choice for?
My Digital Card plays to its strength in hardware: high-quality NFC cards made of metal or wood (such as the Sigma Card) with QR code as a one-time purchase, where access to the MDC-Cloud is included free of charge in the card price, so no additional monthly user subscription applies. For individual users or small teams for whom an elegant physical card plus a simple online profile without an app matters more than central IT administration, My Digital Card can be the right solution.
What do oneVcard and My Digital Card cost?
We deliberately do not list specific prices, as they change frequently and are not transparently and completely available for all providers. oneVcard offers a permanently free Lite plan and a Premium plan, a classic, plannable SaaS model for teams. My Digital Card does not follow a subscription model but primarily sells physical cards (one-time purchase) with a free MDC-Cloud; for companies there are volume discounts and an individual or white-label dashboard on request.
My Digital Card does not publicly disclose specific per-user prices for B2B use. It is best to inquire about the current conditions directly with the respective provider.
