About this app

Idha Reader reads your digital tachograph driver card and uploads the data to IDHA Online — directly from your Android phone or tablet.

Connect a USB smart card reader, insert your driver card, and the app reads the full card and sends the signed .ddd file to your IDHA Online account. No computer required.

FEATURES
• Sign in securely to IDHA Online (OIDC) — switch between multiple accounts
• Reads driver name, card number and validity dates
• Reads all card files and digital signatures into a complete .ddd download file
• Supports both Generation 1 and Generation 2 tachograph cards
• Automatic card detection — reading starts as soon as you insert the card
• Real-time progress while reading and uploading
• Available in English, Swedish, Danish, Norwegian, Finnish and Portuguese

REQUIREMENTS
• An Android device with USB host support (most modern phones and tablets)
• A CCID-compliant USB smart card reader — a USB-C reader plugs in directly; a USB-A reader needs a USB-C-to-USB-A cable/adapter
• An IDHA Online account

Idha Reader implements the EU tachograph card protocol (Reg. 3821/85 / 165/2014) and assembles a standards-compliant .ddd file for archiving and analysis on IDHA Online.

Note: smart card reading requires external USB hardware. The app stays installable on devices without USB host support, but a reader is needed to read a card.
