Common QR vs. app-specific QR: which to use when
Last updated:
For one destination, addressQr makes a common QR and app-specific QRs. Here is how to choose, and how one-time QRs differ.
Common QR: the driver chooses the app
Scanning the common QR shows the destination and a list of navigation app buttons. The driver taps their usual app to start.
- When many drivers come and you don't know which apps they use
- For first-time visitors, partners and foreign drivers
- When sending the link by SMS or messenger
App-specific QR: scanning opens that app
A QR tied to one app, such as TMAP only or KakaoMap only. Scanning skips the list and starts navigation in that app. If the app is missing or auto-launch is blocked, one large button appears, and the driver can switch to another app.
- When your company uses a specific navigation app
- Places where drivers need to leave quickly, like a gate sign
When posting several QR codes
If the common QR and app QRs are placed side by side, the camera may read the neighboring code first. On the share screen, pick one QR at a time from the tabs to save or print, and keep them well apart. "Print all" prints each QR on its own page.
Remembering the default app
If the driver checks "Always open this app from now on" on the common QR screen, that phone opens the same app automatically after one second from the next QR. For regular drivers, the common QR then works like an app-specific QR.
Permanent QR vs. one-time QR
- With a place name, the QR is permanent and stays in "My QR" on the device that made it. Good for warehouses and shops.
- Without a place name, it becomes a one-time QR that expires in 7 days. Good for single deliveries or temporary sites, and it is not listed.
