Devices & scanning
Devices and staff access
See which phones are connected, disconnect or sign out a device, revoke a person’s access, and understand how device limits and 24-hour connections work.
You decide which phones can reach your inventory. Phones connect with a single-use QR code, every connection ends after 24 hours, and you can cut off a device or a person at any time.
Device limits
Your plan sets how many phones can be connected at the same time: 2 on Starter, 5 on Growth, 15 on Pro and unlimited on Enterprise. Staff accounts are unlimited; only connected phones count.
When the limit is reached, Connect device is turned off and Devices shows Device limit reached. Disconnect a phone or upgrade. If someone reconnects the same phone, the new connection replaces the old one, so it isn’t counted twice.
The Devices page
Open Devices in the Shopify app (the page is titled Mobile devices). At the top you’ll see:
- Connected now — connected phones out of your plan’s limit.
- Pending QR code — the last four characters of a code that hasn’t been used yet, and when it expires.
- Access revoked — how many people are blocked, with a link to review them.
Below, the tabs Connected, Disconnected, Access revoked and All list each device with the staff member, phone model, operating system and app version, status, time left on the connection and last activity.
To connect a phone, click Connect device. See Install Rack Scanner and connect a phone.
Device actions
Open a device’s menu:
| Action | What happens |
|---|---|
| View details & history | Device details, scans on this connection, count sessions from the device and a history of every event |
| Disconnect | Ends this phone’s connection. The person can reconnect by scanning a new QR code |
| Force logout | Ends the connection and also signs the person out of the app on that phone |
| Revoke access | Disconnects all of that person’s devices and blocks them from reconnecting until you restore access |
| Restore access | Lets a blocked person connect again, and shows a fresh QR code for their phone |
The device history shows events such as Connected with a QR code, Connection expired after 24 hours, Disconnected, Signed out of the app, Access revoked and Replaced by a newer connection, with who did it and when.
The Staff page
Staff lists everyone who has connected the app to your store, with their access (Allowed or Revoked), active and total devices, scans, the date they joined and when they were last active. Search by name or email.
Click Revoke to block someone; their devices disconnect right away. Click Restore to let them connect again with a new QR code.
Tip: When someone leaves your team, revoke their access instead of only disconnecting the phone. A disconnected person can reconnect with any new code; a revoked person can’t.
What staff see
When a connection ends, the app returns to Connect Store with the reason, for example Your store connection expired after 24 hours. Scan a new QR code to reconnect. A blocked person who tries to connect sees Your access to this store has been revoked by the merchant.
In the mobile app’s Settings, staff can see when their connection expires, tap Disconnect store to end it themselves, or Log out of the app.
When your plan changes
- Downgrading to a plan with fewer devices disconnects the extra phones. Rack Scanner keeps the most recently active ones connected, and the Plans page warns you before you switch.
- Without an active plan, all phones are disconnected and new phones can’t connect.
