NFC Integration

NFC (Near Field Communication) allows the TAS platform to read NFC cards or chips by placing a mobile device or tablet near them. The feature can be used in two ways: for user authentication via an NFC card or for opening specific cases at a workstation.

Prerequisites

• The NFCenabled parameter must be activated in the environment configuration.
• The device (phone or tablet) must support NFC and have it enabled in the operating system settings.

Use Cases

1. Opening a Case via NFC Chip

Typical use in manufacturing or at workstations — an NFC chip (or card) is placed at each station. When a device is held near it, the assigned case opens automatically, for example a 5S form.

The NFC chip must contain data in JSON format:

{"caseId":415439}

2. User Login via NFC Card

The NFC module can be activated on the login screen. When a card is held near the device, the system reads the identifier stored on the card, looks up the corresponding user (e.g. using a dynamic table) and performs the login.

Setting Up the NFC Reader in the Dashboard

1. Go to the Dashboard editor.
2. Add a new container named NFC Reader.
3. The container will display a button — pressing it activates NFC reading.
4. Hold the device near the chip. The system reads the data and opens the corresponding case.

Setting Up NFC Authentication

1. In the authentication settings, add a new authentication.
2. Select NFC as the module.
3. Insert the configuration in JSON format (see below).

Configuration Example — Looking Up a User in a Dynamic Table

This example reads the identifier from the NFC card, finds the corresponding record in the dynamic table NFCtest, and logs in the user from column COL_1.

{"postAuthInstructions":"debug.log(Holder.getTextProperty('req'));\nconst cardId = Holder.getTextProperty('req.body.additionalData');\nconst cardIdCleaned = cardId.replaceAll('\"', '');\ndebug.log(cardIdCleaned);\nconst userId = dt.from('NFCtest').whereIndex(cardIdCleaned,'=').getFirst().COL_1;\ndebug.log(userId)\nreturn identity.findUser(userId);","instruction":{"cs":"Přiložte NFC kartu k zařízení","en":"Place your NFC card or device near the reader.","de":"Halten Sie Ihre NFC-Karte oder Ihr Gerät an das Lesegerät."}}

Result

After correct configuration:

• Pressing the button in the NFC Reader container activates NFC reading and holding the chip near the device opens the corresponding case.
• The login screen displays a prompt to hold the NFC card near the device. After scanning, the identified user is automatically logged in.
