Plenty of apps will share your contact info. Only one free card also captures the lead, ranks it, and lives inside a full door-to-door sales CRM. Here's the field, and how they stack up.
Updated 2026 · positioning, not live prices — check each vendor for current plans
A digital business card should do more than replace paper. For a rep, the real question isn't "can I share my info" — every app does that — it's "what happens to the person after they save me?" Most cards stop there. The ones worth using capture the contact, tell you when they're interested again, and ideally connect to the tools you actually sell with. Here's how the popular free options compare on exactly that.
Free forever. Shares by tap, QR, or text; captures every contact on a map; free AI ranks your warmest leads; reviews and referrals built in. The only free card that's part of a full door-to-door CRM — and it comes in every paid plan too. See the card →

For a door-to-door or field sales rep, FieldStacker Card is the strongest free option: it shares by tap, QR, or text, captures every contact on a map, ranks your warmest leads with free AI, and is the only free card that is built into a full sales CRM. Blinq and HiHello also have genuine free tiers if you just want a networking card. RepCard and Popl are polished but lean paid for the features that matter most.
It varies. FieldStacker Card, Blinq, and HiHello all have real free tiers. RepCard is a paid subscription. Popl has a free basic tier and charges for team and analytics features. Always check each vendor's current pricing — this list reflects general positioning, not live prices.
Your contacts do not just sit in a vCard. FieldStacker captures each one with where you met them pinned on a map, tells you which leads are warmest, and keeps everything inside a door-to-door sales CRM. The card is free and standalone, and it is included in every paid plan — so if you ever want to knock a route, quote at the door, or track commission and 1099 taxes, your whole network is already there with nothing to re-enter.
No. FieldStacker shares on-screen by QR or link, so there is no accessory to buy, carry, or forget — you get the same instant "save me to your phone" moment plus an open notification. If NFC hardware is your priority, Popl and similar brands specialize in it.
Yes. The FieldStacker card is free on its own and built into every paid plan. Upgrading adds the knock map, doorstep quoting, and financials on top — it never removes the card or your contacts.
A real free digital business card — and if you ever want more, the whole door-to-door stack is one flat bill away, with nothing to re-enter.
