oneVcard Lite is permanently free, includes one digital business card, and requires no payment method on file. QR code and wallet integration are included; the paid Premium plan (up to five cards, Designer, Analytics) builds seamlessly on top of it. oneVcard hosts exclusively in Germany (Frankfurt, with redundancy in Nuremberg) and provides a data processing agreement (DPA) under Art. 28 GDPR, the strongest data protection starting point of the three, even in the free entry tier.
Blinq Free offers two digital business cards, unlimited sharing (QR, wallet, email, SMS), and an email signature already in the free plan, the broadest free feature scope in the comparison. The Premium plan is paid (annual payment). Blinq achieves the highest external user satisfaction with a G2 rating of 4.8/5 (over 8,800 reviews), but hosts on Google Cloud without dedicated EU or Germany data residency; a DPA is not publicly available.
HiHello Personal is free, allows up to four digital business cards, includes an email signature generator, and limits contact scans to five per month. The Professional plan is paid (annual payment). HiHello is SOC 2 Type II certified but hosts the data exclusively in the USA (Google Cloud, Iowa), without an EU/DE option and without German-language support.
