# Field work

Labels and scanning, checklists and work orders, and working with no signal.

- [Labels and QR codes](https://cablefolio.com/help/labels-and-qr-codes/): 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.
- [Checklists and work orders](https://cablefolio.com/help/checklists-and-work-orders/): A checklist is a procedure on a property — commissioning, handover, an annual service — ticked off step by step from a phone and signed off by the customer; a work order lists the devices, runs, and checklists a job covers.
- [Offline](https://cablefolio.com/help/offline/): Cablefolio keeps working in a plant room, a basement, or a lift: keep a property on your phone before you go, and every change you make with no signal waits in a queue and is sent, in order, when the signal returns.
- [How offline sync works](https://cablefolio.com/help/offline-sync/): Cablefolio is built to be used where there is no signal, and this page explains what it keeps on your phone, how the changes you make offline reach everyone else, and why it never guesses when two people changed the same thing.
