Idha Reader

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.
