Public transport is entering a new era of connected and intelligent fare systems — where every on-board device works together to make mobility faster, safer, and easier.
At the center of this evolution stands Digitax ATOMO 7, the compact Android-based validator that turns contactless technology into a complete mobility experience.

1. A DEEP LOOK INTO THE HEART OF CONTACTLESS MOBILITY

Behind every “tap” on ATOMO 7, there is a complete chain of technology working in the background. The front touchscreen, RFID/EMV reader and QR scanner guide the passenger through a clear, intuitive experience — while the internal Android platform manages validation rules, security checks and communication with the back-office.

By concentrating contactless validation, EMV open payment and barcode reading in a single device, ATOMO 7 becomes the operational core of modern fare collection. It doesn’t just read cards and codes: it verifies entitlements, applies the correct fare policy and returns instant feedback to the passenger, even in high-traffic conditions. In the following sections, we open up this validator “from the inside” to show how its design, connectivity and integration capabilities translate into reliable performance on every vehicle.
