Getting started
Add a 3D card
Tap the add button at the top of the app and select a USDZ file. Review the name and company, choose My cards or Received, and save. You can also add a USDZ received through Files, Mail, AirDrop, or another source by choosing to open it in 3D Card Wallet.
Find a card
Enter a registered name or company in the search field. Use the category control to view all cards, your own cards, or received cards.
View in 3D
Open a card, drag to rotate it, and pinch to zoom. Reset returns the card to its starting view. Standard Quick Look and AR viewing are also available.
Share
The share button passes the selected USDZ file to the iOS share sheet. You choose the destination and method.
Send directly nearby
The sender opens Send nearby from a card, while the recipient opens the receive button in the wallet. Both people should enable Wi-Fi and Bluetooth and allow Local Network access for the app. Confirm the person and matching code, then the recipient approves and saves the card.
FAQ
Which files can I add?
3D Card Wallet supports USDZ 3D models. The current import limit is 100 MB. A file is not saved if its package structure or 3D model cannot be validated and loaded.
What are the two cards included on first launch?
They are public demos built entirely with fictional information. A new installation adds them on its first launch. You can edit or delete them like ordinary cards, and deleted demos do not automatically return.
Can I add the demos again later?
When an included public demo is available to add, the app shows Add 2 public demo cards in the empty state or near the top of the wallet.
Is my private note sent with the card?
No. Nearby exchange sends the USDZ file, registered name, and company. The on-device note is excluded. The standard share sheet receives only the selected USDZ file.
Why does AR request camera access?
The camera is used only after you choose AR viewing, so iOS can place the 3D card in your surroundings. The app does not independently save the AR camera feed or send it to D.Dealing servers.
Will my cards transfer automatically to a new iPhone?
3D Card Wallet currently has no app-specific iCloud sync, export backup, or bulk restore. Operating-system backups may include app data, but migration and long-term preservation are not guaranteed. Keep important USDZ originals outside the app as well.
Can I add the same card twice?
The same USDZ content is not added twice. Two USDZ files with the same display name but different content can be stored as separate cards.
Deleting data
Delete an individual card from its menu in the app. To remove all app data, first share or preserve any USDZ files you need, then uninstall 3D Card Wallet. Copies shared outside the app must be removed from their destinations separately.
