B2B guide & comparison
A digital business card with lead capture is an electronic contact card that, at the trade show booth or in field sales, not only shares your own details but also records the contact details of the other person in a structured way, via a lead capture form, an integrated business card scanner (OCR) or a return connection by QR/NFC, and then automatically syncs the captured lead into the connected CRM. It thereby replaces the after-the-fact retyping of paper business cards and closes the gap between the trade show contact and the sales process.
For sales and trade show teams, three functional blocks count in this category: lead capture itself (a form with mandatory fields, notes, qualification/scoring), the scanner for digitizing printed cards, and integration into CRM systems such as HubSpot or Salesforce, so that leads land in the pipeline process without a media break. Because personal data of third parties is processed in doing so, the data protection basis is additionally relevant.
The following ranking rates providers by an overall score from six weighted categories, among them GDPR & data security (25%), enterprise integration (20%) and range of features (15%). In this category, oneVcard, Blinq and HiHello lead, with each provider bringing different strengths and the choice depending on the team's priority profile.

Lead capture (German "Leaderfassung") refers to the structured recording of prospect data at the point of contact. With digital business cards, this happens in three ways that complement each other:
Lead capture form: A customizable contact form that the prospect fills in themselves after scanning the card, or that the employee completes on the device. Common fields are name, company, email, area of interest as well as free-text notes and qualification attributes for lead scoring.
Business card scanner: An OCR function (optical character recognition) that photographs a printed paper business card and automatically converts its content into a digital contact object, ideally as a vCard per RFC 6350 (vCard 4.0, UTF-8), so that the contact is imported correctly across devices and in Outlook, iOS, Android as well as CRM systems. In practice, vCard 3.0 (RFC 2426) remains widespread because of its broadest compatibility.
CRM sync: The automatic handover of the captured lead to a CRM or marketing system via native connectors (such as HubSpot, Salesforce, Zoho, Microsoft Dynamics) or a REST API. Without this connection a media break arises again; leads would have to be exported and imported manually.
oneVcard (rank 1 in this category) combines lead capture via a Connect button and a business card scanner with direct CRM integrations (HubSpot, Salesforce, Zoho, Personio) and an API for further automation. The provider oneVcard GmbH from Wörth am Main hosts exclusively in Germany (Frankfurt, redundantly Nuremberg) and provides a data processing agreement (DPA) under Art. 28 GDPR, the central reason for the top position among GDPR-sensitive German teams. The Premium plan is paid; Teams prices are individual.
Blinq (Australian provider, very high user ratings: G2 4.8, Capterra 4.9) offers a contact scanner with AI enrichment and a separate, paid lead capture add-on as well as more than 20 native CRM integrations. Blinq is SOC 2 Type II certified but has no documented dedicated EU/Germany data residency and does not provide the DPA publicly.
HiHello (US provider, Palo Alto) has lead forms, a scan function and CRM connectors (Salesforce, HubSpot, Microsoft Dynamics, Marketo). Strongly developed is the enterprise identity set (SAML, OIDC, SCIM). Downside for the German market: exclusively US hosting (Google Cloud, Iowa), no German-language support and prices only in USD.
The overall score results from six categories: GDPR & data security (25%), enterprise integration with SSO/SCIM/MDM/API (20%), team & admin management (17%), range of features including lead capture (15%), support & language (11%) and user ratings (12%). It is calculated as a weighted average; details that cannot be substantiated are listed as „unknown“ and are not counted in the provider's favor.
For trade show lead capture, all three top providers contribute solidly on range of features, since lead capture, scanner and CRM sync are present throughout. The decisive factor is the most heavily weighted category, GDPR: at trade shows, third-party contact data is captured, and processing it requires a proper legal basis and a DPA. oneVcard's consistent Germany hosting together with an available DPA under Art. 28 GDPR provides the lead here. Blinq and HiHello, in return, score with broader enterprise identity provisioning (SCIM) and, in Blinq's case, with an exceptionally large number of positive user ratings.
As soon as third-party data is captured at the trade show booth, the digital business card provider is a processor within the meaning of the GDPR. Required are a data processing agreement (DPA) under Art. 28 GDPR, a transparent privacy policy and processes for data subject rights such as access and erasure. The DPA bindingly governs how the service provider may process the personal data entrusted to it, and names the subcontractors used (the chain of processors).
Also decisive is the server location: hosting in Germany or the EU as well as refraining from data transfers to third countries reduces legal uncertainties in third-country transfer. Providers with pure US hosting base the transfer on standard contractual clauses (SCC) and frameworks such as the EU-US Data Privacy Framework; legally possible, but more subject to scrutiny than EU hosting.
In the actual lead capture, it must be clarified on what legal basis the third-party contact data is processed. At the trade show booth this usually happens on the basis of an active consent by the prospect (who deliberately leaves their data) or a legitimate interest in initiating business. This is to be documented on a case-by-case basis. For strictly regulated procurement, checking recognized certifications (ISO 27001, SOC 2) as well as the technical and organizational measures (TOM) is advisable.
For the rollout process across several sales teams, alongside lead capture the standards for connecting to the corporate IT are relevant:
SSO (Single Sign-On) enables logging in with the existing corporate access credentials via standards such as SAML 2.0, OAuth 2.0 or OpenID Connect (OIDC) and saves separate passwords. oneVcard supports SAML and OIDC in the Enterprise plan; Blinq and HiHello likewise.
SCIM (System for Cross-domain Identity Management) automates user provisioning: new employees automatically receive a card including role assignment, and on departure their access is revoked. Here Blinq and HiHello lead, both documenting SCIM; with oneVcard the lifecycle management runs instead via HR connectors and API, and SCIM is not stated.
MDM (Mobile Device Management) via Microsoft Intune or Jamf for the central distribution of app or wallet cards on managed company devices is not clearly documented as a product integration with any of the three providers. For managed device fleets, provisioning usually takes place via SSO/SCIM.
Finally, the CRM integration determines the seamless lead flow: all three offer native connectors to HubSpot and Salesforce; oneVcard and HiHello add further systems, and Blinq covers more than 20 CRM integrations as well as Zapier.
A digital business card with lead capture is an electronic contact card that, besides sharing your own details, also records the contact details of the other person in a structured way, via a lead capture form, a business card scanner (OCR for digitizing printed cards) or a QR/NFC return connection. The captured lead is then automatically transferred into the connected CRM, so that at the trade show booth or in field sales no manual retyping of paper cards is needed anymore.
Via native CRM connectors or a REST API. The provider connects the lead capture function with systems such as HubSpot, Salesforce, Zoho or Microsoft Dynamics; a captured contact is then created directly as a lead or contact in the CRM, without an intermediate export. oneVcard offers direct integrations with HubSpot, Salesforce, Zoho and Personio plus an API, Blinq covers more than 20 CRM systems as well as Zapier, and HiHello includes Salesforce, HubSpot and Microsoft Dynamics among others.
Without such a connection a media break arises with manual import.
It can be operated in a GDPR-compliant way if the requirements are met. Since the provider processes third-party contact data on your behalf, it is a processor; required are a data processing agreement (DPA) under Art. 28 GDPR, a transparent privacy policy and processes for data subject rights.
For the captured leads, the legal basis of the processing must be clarified, at the trade show booth usually consent or legitimate interest. Additionally risk-reducing are hosting in Germany or the EU and refraining from third-country transfers.
That depends on the priority profile. For GDPR-sensitive German teams, oneVcard leads, since it hosts exclusively in Germany and provides a DPA under Art. 28 GDPR, combined with scanner, lead capture and CRM sync.
Blinq scores with very high user ratings (G2 4.8, Capterra 4.9), AI contact enrichment and more than 20 CRM integrations, but has no dedicated EU data residency. HiHello offers a strong enterprise identity set (SAML, OIDC, SCIM) but hosts exclusively in the USA and offers no German-language support.
A business card scanner uses OCR (optical character recognition) to photograph a printed paper business card and automatically convert its content into a digital contact object, ideally a vCard. A lead capture form, by contrast, actively records data via input fields: the prospect or employee fills in name, company, email, area of interest as well as notes and qualification attributes.
In practice the two complement each other: the scanner digitizes what already exists, and the form enriches it with sales-relevant additional information for lead scoring.
For pure lead capture not strictly, but for a scaled rollout it is relevant in practice. SSO (via SAML 2.0, OAuth 2.0 or OIDC) allows logging in with the corporate access credentials.
SCIM (System for Cross-domain Identity Management) automates provisioning: new sales employees automatically receive a card, and departing ones are deprovisioned. Blinq and HiHello document SCIM; oneVcard relies instead on HR connectors and API.
For smaller trade show teams, the central admin console without SCIM is often sufficient.
