Pull Balance, Top-Up Amount, and Travel History from Any Transit Card Screenshot
Reconciling transit expenses across Suica, Oyster, T-money, and Opal means opening 4 different apps and manually copying balances into a spreadsheet — this pulls the data you need from any transit card screenshot in 5 seconds.

What You Can Pull from Transit Card Screenshots
A Suica gate, an Oyster reader, and a T-money receipt look nothing alike. With Custom Column Extraction, you name the fields — the AI finds them by understanding what each value means, not where it appears.
The column names you type for each system. The AI finds matching values regardless of hardware — one clean spreadsheet across cards from different countries.
These Screenshots Come from Gates, Readers, and Apps — but the Fields You Need Are the Same
A Suica gate shows your balance on a large digital display. An Oyster reader shows it on a compact yellow LCD. T-money shows it on the beeping gate. Traditional extraction tools look for tables — transit card interfaces don't draw tables. Here's what breaks, and how semantic extraction finds the same data across completely different hardware.
Why Transit Card Screenshots Break Traditional Extraction
No two transit systems display a balance the same way. Suica shows ¥1,280 on a green gate screen. Oyster shows £12.40 on a yellow reader pad. T-money shows ₩3,500 on the beeping gate. Template-based OCR needs per-system training for something as simple as a balance check.
Screenshots come from hardware or apps — and they mix in a batch. On r/japanlife, users note that "you can print out your expenses at a ticket machine" — a photo of a printed receipt, a phone screenshot, and a snap of the gate reader all end up in the same folder. No existing tool handles all three input types from one system, let alone across twelve countries.
Currency signs, dates, and language vary with every screenshot. A Suica receipt uses ¥ with Japanese dates (2026年07月). An Oyster top-up uses £ with DD/MM/YYYY. Basic OCR dumps these as raw mixed-format text — you spend more time normalizing than you would typing them in.
How Semantic Extraction Finds Transit Data Anywhere
You name the columns — AI locates balances, top-ups, and dates by meaning. Type "Balance", "Top-Up Amount", "Top-Up Date". The model understands what a transit balance looks like — whether it's the ¥ figure on a Suica gate, the £ display on an Oyster reader, or the ₩ amount on a T-money receipt. You never tell the AI which gate or app you're using.
One column set across twelve transit systems in a single batch. Upload Suica gate photos, Oyster reader screenshots, and T-money receipts together. Define columns once. The AI adapts to each system's layout individually — every screenshot becomes a row in the same spreadsheet.
Currencies normalized on extraction. ¥1,280 from a Suica gate and £12.40 from an Oyster reader — the AI reads currency and value together, giving you a clean Balance column instead of mixed-format text.
From Photos of 3 Different Transit Card Screens to One Expense Log in 3 Steps
Upload Mixed Transit Card Screenshots
You've got a Suica balance photo taken at a JR East gate, an Oyster card balance from the yellow reader at a tube station, and a T-money top-up receipt from a Seoul convenience store. Three completely different devices, three countries, three currencies. Drag them all into one batch — JPG, PNG, or WebP, no pre-sorting by card type.
Name the Fields You Need Across All Three
Type Balance, Top-Up Amount, Top-Up Date, Transit System. One set of columns, one batch. The AI doesn't need to know which screenshot is a Suica gate and which is an Oyster reader. It reads each image, identifies the balance by its visual context (large digital figure on a gate display, compact LCD on a reader pad), and fills in the row.
Export a Single Transit Expense Spreadsheet
Processing takes 5-10 seconds per screenshot. The output is one XLSX or CSV file: three rows (one per transit card), exactly the columns you defined. Suica, Oyster, and T-money in one table with balances in ¥, £, and ₩ normalized into the same column. Roughly 18x faster than opening each screenshot and typing the fields by hand.
When It Works Best — and When to Be Cautious
Honest boundaries help you get reliable results from transit card screenshots.
When It Works Best
Direct phone screenshots of transit apps and NFC wallets. Full-resolution screenshots of Mobile Suica or the Oyster app achieve up to 99% accuracy on printed numerals.
Predictable key-value patterns across systems. A balance paired with a currency sign — these relationships hold whether from a Tokyo gate, London reader, or Seoul terminal. The AI finds them by meaning, not layout.
Mixed-system batch processing. One column set, different transit systems, single spreadsheet.
When to Be Cautious
Angled photos of gate or reader displays with glare. A quick snap in bright overhead lighting introduces reflections. A straight-on photo produces better results.
Old-style segmented LCD displays on older fare gates. Older machines use seven-segment digits that may appear broken in photos. The model handles these better than traditional OCR, but spot-check balances.
Heavily localized app versions with no English text. The AI reads numerals regardless of language, but column names work best when currency signs are identifiable. Purely numeric gate displays are unaffected.
Frequently Asked Questions
Can I extract the current balance from a Suica gate screen showing a digital yen figure?
Yes. Name a column Balance and the AI reads the large digital figure displayed on the Suica or PASMO gate screen after you tap out. The yen sign (¥) is typically shown above or beside the number depending on the gate model — the AI identifies the figure by its size, position, and relationship to the surrounding UI. This works for both the older green JR East gates and the newer models.
What if my Oyster card screenshot shows the balance on the small yellow reader display — can the AI read that tiny LCD?
Yes, the visual model handles the compact LCD digits on the yellow Oyster card readers. The £12.40-style display is high-contrast (black text on yellow background) and uses a consistent font, which is well within the model's capability. Direct, straight-on photos of the reader will be most accurate — angled snaps with glare may reduce precision for the smaller digits. The reader also briefly shows "AMOUNT" or "BALANCE" labels that help the AI locate the correct value.
Can I batch process Suica, Oyster, and T-money screenshots together with a single set of columns?
Yes. This is one of the strongest use cases for semantic extraction over template-based tools. Define one column set — Balance, Top-Up Amount, Top-Up Date, Transit System — and upload a Suica gate photo, an Oyster reader snap, and a T-money convenience store receipt into the same batch. The AI processes each screenshot independently and fills in the fields it finds. The output is a single spreadsheet with one row per transit card, even though the three screenshots come from different countries, currencies, and hardware devices.
How should I handle transit card screenshots for business expense reporting?
Create a column set that includes Balance Before, Top-Up Amount, Date, Transit System, Purpose (using an Inferred Column with options like Commute/Business Trip/Personal). Upload your batch of screenshots — the AI extracts the monetary fields and categorizes each trip in one pass. Export to Excel for direct submission to your expense system. For recurring commutes, you can save the column set as a template so each monthly batch uses the same definitions.
Can the AI extract trip history — the stations I traveled between — from a transit card screenshot?
It depends on what the screenshot shows. Many transit card apps (Mobile Suica, TfL Oyster app, Opal Travel, SimplyGo) display a recent trip history with station names, dates, and fares. If the screenshot includes this list, you can define columns like Start Station, End Station, Fare, Trip Date and the AI will extract them. Gate readers typically only show the current balance, not trip history, so for route-level data, prioritize app screenshots over device photos.
