Networking ring, card, or QR code for an event?
Match the sharing method to movement, visibility, recipient comfort, and the fallback your team can actually support.
A comparison from Ping, the maker of Ping Ring. Based on published product information; not a hands-on test of competing products.
THE SHORT ANSWER
A ring suits repeated one-to-one introductions when the wearer likes the format. A card provides a familiar physical handoff. A displayed QR code helps when many people need access to one destination. Use the method that fits the interaction and keep a fallback.
Use interaction shape as the starting point
For a moving one-to-one conversation, a wearable NFC ring can keep the sharing tool close. For a deliberate exchange across a table, a card may feel familiar. For a booth or sign serving several visitors, a visible QR code can let people scan independently.
These are scenario judgments, not measured conversion claims. dot.cards publicly offers cards and bands as well as QR and NFC sharing, while Ping's product perspective centers the ring. The category includes several valid formats.

Test visibility and recipient effort
A recipient should understand what is being offered before scanning or tapping. Put the destination's purpose beside a displayed QR code. For NFC, explain where to hold the phone and wait for the prompt. For paper, make the next action legible.
Google documents creating QR codes for pages in Chrome, but generation is only the start. Test the printed size, contrast, distance, lighting, and destination with representative phones. Do not collect information merely because somebody scanned a sign.

Design the fallback at the same time
A ring can fall back to a direct link or QR code. A QR display can include a readable URL. A paper card can include both a short destination and a QR code. Redundancy is useful when it reduces friction rather than adding a wall of choices.
For teams, also decide who maintains the destination and how outdated materials are removed. Verify current provider features and terms directly; this article does not claim hands-on testing or platform parity.
| Setting | Natural starting point | Fallback |
|---|---|---|
| Repeated one-to-one introductions | Wearable ring | Direct link or QR |
| Seated exchange | Physical or digital card | Readable contact route |
| Booth or shared display | Labeled QR code | Short URL and staff-assisted sharing |
