CM Mobile does not support registering two tags to a single client. However, if you use NFC-only tags, you can duplicate a tag using the NFC Tools app.
Register the tag to the client in CM Mobile first.
Download the NFC Tools app from the App Store or Google Play Store.
Open the app and tap Other.
Select Copy to Infinity — use this option if the tag needs to be copied multiple times.
Confirm the duplicate tags are linked to the correct client in CM Mobile.
🤓Tip: If you make a mistake and have duplicate tags linked to the wrong client, use the Erase Tag option in NFC Tools to remove them.
