My Digital Card (MDC)

My Digital Card (MDC) is operated by Relativity GmbH, based at Breite Straße 25 in 13597 Berlin. Unlike pure software providers, MDC comes from the hardware side: at its core are physical NFC business cards made of metal or wood, as well as the MDC Tag and the Sigma Card, available in the Shopify-based online store.

Every card includes free access to the cloud-based profile platform MDC-Cloud, which is used to manage contact details, links and branding. Contact exchange works via NFC tap or QR scan without a separate app.

In our overall assessment, MDC scores 51 out of 100 points, positioning it as a solid entry-level and SME tool whose strength clearly lies in card quality rather than software depth. For companies, there is also a corporate dashboard that can be used to design employee cards, track success and scale via volume discounts and a white-label dashboard.

Data protection reveals MDC's biggest weakness, which is reflected in its low GDPR category score of 40 out of 100 points. While the operator is a German GmbH based in Berlin, this does not replace a documented server location.

The MDC-Cloud is technically implemented as a no-code application on the US platform Bubble.io – recognizable by server headers such as x-bubble-* and by images from cdn.bubble.io – and is delivered via Cloudflare. Bubble hosts by default on AWS in the USA; EU hosting is only available in higher Bubble tiers and cannot be verified for MDC.

A German or EU server location is therefore not documented (serverLocationGermany: false). Likewise, a data processing agreement (DPA) under Art. 28 GDPR, ISO 27001 certification or a SOC 2 report are not evidenced. For B2B buyers, this means that the question of data transfer to the USA must be carefully examined before deployment.

At least the provider references data protection and legal notice pages of the MDC-Cloud, but reliable compliance documents are missing.

For B2B use, MDC delivers an existing but lightweight offering – this is reflected in the category scores for team and admin features (55 out of 100) and enterprise integration (25 out of 100). On the positive side: there is a corporate dashboard for centrally designing employee cards, along with success tracking, bulk provisioning and a white-label dashboard – features that many pure hardware sellers do not offer.

For centrally managing medium-sized teams, this is often sufficient in practice. However, it becomes thin when it comes to the classic enterprise features: verifiable SSO methods (SAML, OIDC or SCIM), MDM connectivity, Entra ID provisioning or granular role and permission concepts are not evidenced.

Likewise, there is no public API and no named CRM integrations; wallet or email signature features are not documented. MDC is therefore purely a contact profile platform with a team layer on top, not full-fledged enterprise software.

The low enterprise score of 25 points reflects exactly this gap.
