Como escanear um cartão de embarque com o celular: guia passo a passo

Gone are the days of manually typing in flight numbers, airport codes, and dates every time you want to log a flight. Modern AI-powered boarding pass scanners can extract all your flight data in seconds, from a crumpled paper pass to a screenshot on your phone. In this guide, we walk you through exactly how it works and share tips to get perfect results every time.

What Data Can Be Extracted from a Boarding Pass?

A standard boarding pass, whether paper or digital, contains a wealth of information encoded in both human-readable text and a machine-readable barcode (typically a PDF417 or Aztec code following the IATA BCBP standard). Here is what a good scanner can pull:

• Flight number: e.g., AF 1234
• Departure and arrival airports: IATA codes (CDG, JFK) or full names
• Date of travel: departure date, sometimes with time
• Seat assignment: e.g., 14A
• Cabin class: Economy, Business, etc.
• Passenger name: for identification
• Booking reference: PNR code

How AI Boarding Pass Scanning Works

Traditional OCR (Optical Character Recognition) reads text character by character, which works reasonably well on clean, high-contrast printed text but struggles with wrinkled paper, unusual fonts, partial obstructions, or low-resolution screenshots. That is where AI vision models change the game.

FlightLog uses GPT Vision, a multimodal AI model, to understand boarding passes the way a human would. Instead of looking for specific text patterns, the model sees the entire image, understands the layout, recognizes airline branding, and extracts structured data even from heavily styled or damaged passes.

This means it works with virtually any boarding pass format: airline-branded thermal prints, mobile screenshots from airline apps, PDF boarding passes, Apple Wallet passes, and even boarding passes in non-Latin scripts.

Step-by-Step: Scanning a Boarding Pass with FlightLog

Step 1: Open the Scanner

Tap the central scan button on the tab bar. FlightLog's scanner opens with your camera ready. You can also tap the gallery icon to select an existing photo or screenshot.

Step 2: Frame Your Boarding Pass

Hold your phone about 15-20 cm above the boarding pass. Make sure the entire pass is visible in the frame: you do not need to crop precisely, the AI will find the relevant information. For digital passes on a screen, simply take a screenshot first and scan from your gallery.

Step 3: Review Extracted Data

Within a few seconds, FlightLog displays all extracted information: flight number, departure and arrival airports, date, seat, and class. Review the data and make any corrections if needed, though with AI scanning, corrections are rarely necessary.

Step 4: Save Your Flight

Tap save and your flight is added to your journal with all the data pre-filled. FlightLog automatically calculates the distance, estimated duration, and carbon footprint for the route.

Tips for Perfect Scans

• Good lighting matters. Avoid shadows falling across the boarding pass. Natural daylight or evenly diffused indoor light works best.
• Flatten the paper. If the pass is crumpled or folded, smooth it out before scanning. The AI can handle some distortion, but a flat surface gives the best results.
• Include the full pass. Make sure no edges are cut off. The flight number and airport codes are sometimes in corners.
• For screenshots, crop generously. When scanning a digital pass from your gallery, leave some margin around the boarding pass rather than cropping too tightly.
• Use pinch-to-zoom for small text. FlightLog's scanner supports pinch-to-zoom with the camera, so you can get closer to small or faded text.
• Batch scanning is possible. If you have a stack of old boarding passes to log, scan them one by one: each scan takes only a few seconds.

What About Old Boarding Passes?

If you have been saving boarding passes in a drawer or shoe box (and many travelers do), FlightLog's AI scanner is your best friend. Thermal paper fades over time, but as long as the key text, flight number and airport codes, is still partially readable, the AI can usually figure out the rest.

For passes that are too faded to scan, you can also use FlightLog's bulk import feature to add multiple flights at once by typing a simple list of routes (e.g., "CDG-JFK, LHR-SIN, NRT-LAX").

Beyond Scanning: Automatic Enrichment

After scanning, FlightLog does not stop at the data on the boarding pass. It automatically enriches your flight with additional information:

• Full airline name and IATA/ICAO codes
• Aircraft type and registration (when available via ADS-B data)
• Precise airport coordinates for map display
• Great-circle distance between airports
• Estimated CO2 emissions using DEFRA 2024 emission factors

This means every scanned flight instantly becomes a rich data point in your flight statistics, complete with distance, duration, carbon impact, and a route plotted on your interactive 3D globe. Try it yourself: download FlightLog for free and scan your first boarding pass in seconds.
