oneVcard vs. My Digital Card (MDC)
oneVcard 92 /100 
My Digital Card (MDC) 51 /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, run in the company's own ISO 27001 data center in Nuremberg, complemented by enterprise identity features such as SSO (SAML, Entra ID, Google), automated user provisioning, MDM integration (Intune/Entra), and dedicated email signature management for Outlook. My Digital Card comes from the hardware corner: at its heart are high-quality NFC cards made of metal or wood as a one-time purchase, which come with the cloud-based profile platform "MDC-Cloud" included free of charge.
Technically, however, this cloud is built 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 top-tier physical card, but it raises questions for privacy-critical B2B use cases.
This comparison classifies both providers objectively and names the strengths and weaknesses of each side.

Verdict
In the B2B comparison, oneVcard clearly leads (overall score 92 vs. 51) - above all because it covers the typical requirements of larger organizations that My Digital Card does not aim to meet. The decisive difference lies in hosting: oneVcard operates data and development exclusively in Germany in its own ISO 27001 data center in Nuremberg and provides a data processing agreement (DPA) under Art. 28 GDPR.
With My Digital Card, the operator is indeed a German GmbH from 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 (DPA) under Art. 28 GDPR, ISO 27001, or SOC 2 are not documented - a real GDPR risk for companies. In enterprise administration (SSO, MDM, provisioning), integrations (20+ plus REST API), and email signature management, oneVcard is also considerably more broadly positioned, while MDC offers no documented functions 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 a 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 want to roll out digital business cards company-wide, manage them centrally, and host them GDPR-compliantly in Germany, on the other hand, 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) - however, such public reviews are equally absent 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 operates its own ISO 27001-certified data center in Nuremberg; a data processing agreement (DPA) under 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 (DPA) under Art. 28 GDPR, as well as ISO 27001 or SOC 2 are not documented for My Digital Card - a point to check for privacy-sensitive B2B use cases.
Which enterprise features does oneVcard offer that My Digital Card lacks?
oneVcard supports single sign-on (SAML, Entra ID, Google), automated user provisioning, MDM integration via Intune/Entra, as well as 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 are not verifiable - there is a company dashboard with white-label, success tracking, and volume discounts, but it turns out to be rather lightweight and does not replace full-fledged enterprise administration.
For whom is My Digital Card the better choice?
My Digital Card plays to its strength in hardware: high-quality NFC cards made of metal or wood (such as the Sigma Card) with a QR code as a one-time purchase, with access to the MDC-Cloud included free in the card price - so there is no additional monthly user subscription. For individual users or small teams who value an elegant physical card plus a simple online profile without an app more than central IT administration, My Digital Card can be the right solution.
What do oneVcard and My Digital Card cost?
oneVcard offers a permanently free Lite plan and a paid Premium plan - a classic, predictable SaaS model for teams. My Digital Card does not follow a subscription model but primarily sells physical cards (as a 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 concrete per-user prices for B2B use, which makes a direct cost comparison difficult.
