# Labels and QR codes

Category: Field work. Updated 2026-11-10.

Print a QR label for every room, rack, device, patch panel, and run so that scanning one later opens its page, and use the phone's camera or an NFC tag to find a record or read a serial number instead of typing it.

## Print labels for a property or a rack

1. Open the property (or a rack) and press **Labels** at the top of its page.
2. Under **Print labels for**, tick what to print: **Property**, **Rooms**, **Racks**, **Devices**, **Patch panels**, **Runs**.
3. Under **Under the name**, tick the lines each label carries: **Type**, **Path**, **Short ID**, **Serial**, **IP address**, **Cable ID**, **Far end**.
4. Choose the **Stock** you are printing on: a Letter or A4 sheet of die-cut labels, 12, 18, or 24 mm tape, or a 2 × 1 in thermal roll.
5. Press **Print**.

The count under the controls says how many labels and sheets that is, and warns when a label has no room for every line you ticked. Only the labels print. Tape and a thermal roll print one label to a page, so set the printer's paper to the label size shown. Your stock and line choices are remembered on this device.

> Put the room's label by its door. On site, scan the room, then the device, and what you file lands where you are standing.

## Print wire flags for runs

On a property's labels page, tick **Wire flags (both ends)**. Each run gets a flag for each end, carrying its cable ID and where the other end lands, printed after the other labels.

## Scan a label to open its page

On a phone, press the camera button beside the header search box (**Scan a code**).

1. Hold the label in the frame. Nothing happens until you choose.
2. When the code is read, press **Use**, or **Scan again**.

One of this app's QR labels opens that record's page. Any other code is searched for as text. The button is not shown on wider screens.

## Read a label's printed text

Where a label has no QR code — a manufacturer's sticker, a hand-written cable tag — the scan sheet can read its words.

1. Open **Scan a code** and choose **Text** in **Read with**.
2. Choose **One line** or **Several lines** under **Text on the label**.
3. Fit the text inside the box (or drag a new box over it) and press **Read**.
4. The sheet lists the records the text names. Press **Open …** on the right one, or **Search for it** if nothing matched. **Read again** tries once more.

The reading happens on the phone. With no signal, it matches against the properties you kept offline. See [Offline](https://cablefolio.com/help/offline/).

## Read a serial or MAC with the camera

On the device form, the camera button beside **Serial number** and **MAC address** (and beside **Cable ID** on a run) opens the same sheet.

1. Read the barcode with **Code**, or the printed text with **Text**.
2. Check the value shown and press **Use** to write it into the field.

A MAC address is written as colon-separated pairs. Under the MAC field, the form names the maker its prefix belongs to ("Looks like …") as a hint; it never fills in **Make** for you.

## Write an NFC tag

On a room, rack, device, or run page, press **Write NFC tag** and hold a tag flat against the back of the phone.

- A blank tag offers **Write the tag**.
- A tag that holds something else offers **Replace it** or **Keep the tag as it is**.
- Once written, **Lock the tag…** then **Lock it for good** makes it read-only forever. **Leave it writable** keeps it changeable. Locking cannot be undone.

Writing tags needs Chrome on Android; iPhones can still read them.

## Read an NFC tag

Where the phone supports it, the scan sheet offers **Tag** in **Read with**. Press **Read a tag**, hold the tag to the back of the phone, and press **Use** to open what **The tag holds**, or **Read another**.

## When the camera is not available

If the browser cannot scan, or the camera was not allowed, the sheet says so in words and you type the value instead. To allow the camera, change it in the browser's site settings.
