Card Contacts support

Last updated 14 September 2026

Signing in

The sign in link never arrived

Check the spam folder first, then ask for a new link. Links are single use and expire, so the oldest one in your inbox will not work. If several attempts in a row produce nothing, the mail service may be rate limiting you: wait a few minutes and try once more.

The link opens a browser instead of the app

Open the link on the same phone that asked for it, and let it hand off to Card Contacts. If your mail app previews links in its own browser, choose to open it externally.

Sign in with Apple or Google

Both are on the sign in screen. Using Apple's hide my email option is fine; the app only ever needs an address it can reach you at.

Scanning a card

The fields came back wrong or empty

Every field is editable before you save, which is the intended fix. For a better read: fill the frame with the card, keep it flat, and avoid a hard shadow across the print. A glossy card photographs better at a slight angle to the light. If the reader cannot make anything of it, the app hands you an empty draft rather than inventing fields, and you can type it in.

What happens to the photo

The cropped card is sent to our reader service to turn the text into fields, and the image is kept with the contact in private storage under your account. The privacy policy sets out the detail.

Your own card

Sharing it

My Card, then Share card, produces a link and a QR code. Anyone can open it with no app installed, and their phone will offer to add you to their address book.

Revoking it

My Card, then Manage tokens, lists every link you have made. Revoke the one you want and the next person who opens it sees a page saying the card is no longer available. Links you did not revoke keep working, so revoke each one you want dead.

Someone opened my link and saw nothing

A link that was revoked, or one that was mistyped, gives a not found or no longer available page. Send a fresh link from My Card.

Your data

Deleting a contact

Open the contact and delete it. The record and its card image go with it.

Deleting your account

In the app: My Card, then Delete account. The screen lists what goes and asks once more before it acts. It removes your card, every contact, every stored image and every share link you have handed out, immediately and for good.

One thing it cannot reach: a contact you already saved into your phone's own address book stays there, because that copy belongs to your phone. Remove it in Contacts if you want it gone too.

If you would rather we did it, or you want a copy of your data first, write to admin@system-sync.com from the address you signed up with.

Reporting a bug or asking for a feature

Same address. What you were doing, what you expected, and what happened instead is enough. A screenshot helps. Security issues: put "security" in the subject line and we will come back to you quickly.
