Tablet Interface and NFC
TAS offers several features for working on a tablet and on the shop floor: a simplified tablet interface on the dashboard, a custom full-screen case view, opening cases by tapping an NFC tag, and signing in with an NFC card. Which of these work in your installation depends on your administrator's settings and on your process templates.
TabletGUI widget on the dashboard
To add the TabletGUI widget to the dashboard, switch to edit mode and choose Add → TabletGUI. The widget fills the full width and height of the screen. Instead of switching between lists and case detail, you work on a single screen.

| No. | Part | Purpose |
|---|---|---|
| 1 | Case list | Your cases, newest first. The field below the header filters by name. Tap a row to select the case. |
| 2 | Tasks | Tasks of the selected case. |
| 3 | Folder | Selects the folder whose documents of the selected case are shown. |
| 4 | Documents | Documents of the selected case in the chosen folder. |
| 5 | Case detail | Case owner, deadline, template, description, case state, status, start date and actual end. |
| 6 | Event | Triggers an event of the selected case. The button stays inactive until you select a case. |
Tablet case view
A process template can include a print designed as a standalone screen, such as a production or warehouse form. This print opens full screen, without the menu or top bar, at an address in the form /tablet/<ID případu>/<ID tisku> or /gui/<ID případu>/<ID tisku>. The address can also include the ID of another case, a task ID and a tab name. The print uses these values as the template author set it up.
The template author decides what the screen contains and how it works. If your process uses one, your administrator will give you the link.
NFC reader
If your administrator has enabled the NFC reader, you can open cases by tapping an NFC tag, such as a label on a device or a stock item.
NFC reading works only in browsers that support NFC. In practice, this means Chrome on an Android phone or tablet. In other browsers, TAS shows the message "NFC is not supported in this browser. Use Chrome on Android."
NFC Reader widget
- Add the NFC Reader widget to the dashboard (in edit mode, choose Add → NFC Reader). It appears in the menu only when the NFC reader is enabled.
- In the widget, tap Scan NFC.
- A window opens with the text "Hold the card to the centre of the display or to the back of the device." Hold the tag to the device.
- If the tag contains a link to a case, TAS shows "NFC read successfully!" and opens the case.
| Message | Meaning |
|---|---|
| The NFC tag does not contain valid case data. | The tag was read, but it contains no case information. The tag must contain a text record in JSON format with a caseId item. |
| Failed to read the NFC tag. | The tag could not be read. Tap Scan NFC and try again. |
To stop reading at any time, tap Cancel. In the widget settings, you can change the Instruction text shown during reading and add versions in other languages. TAS logs every tag read.
Signing in with an NFC card
Your administrator can enable sign-in with an NFC card. When it is enabled, the sign-in page shows a separate button for signing in with a card.
- On the sign-in page, tap the NFC sign-in button.
- Hold your card to the device as the on-screen instructions describe.
- When the card is read successfully, TAS signs you in.
Your administrator links cards to user accounts in the NFC authentication module.
