Korea Card Balance for T-money

Tap your Korean transit card to the back of your phone and see the balance,
card type, and recent trips — instantly, in your own language, with no
internet connection required.

**Built for tourists.** Korea's T-money-family cards work on every subway,
bus, and most taxis in the country, but the balance never shows on the card
itself. This app reads it over NFC in under a second, converts it to your
home currency, and estimates how many rides are left — so you know before
you're stuck at the gate.

**Features**

- Balance in ₩ and your home currency, updated on every tap
- Card type and brand shown only when the card itself confirms it — never a
guess
- Recent transactions, kept on your phone for as long as you want them, even
though the card itself only holds a couple of dozen
- Estimated rides-left, clearly labelled as an estimate
- Save several cards with your own nicknames — yours, a family member's, a
spare
- An offline Guide: how to top up, how to get a refund when you leave, common
phrases to show transit staff, and general transit tips
- Nine languages: English, 한국어, 简体中文, 繁體中文, 日本語, ไทย, Tiếng Việt,
Bahasa Indonesia, and Español — the app starts in whichever of these is
closest to your phone's language

**Supported cards**

T-money, Cashbee/EZL, Rail Plus, Hanpay/iM One Pass, and tourist cards built
on them, such as WOWPASS and Korea Tour Card. Any card following the same
underlying Korean transit-card standard should work.

**Privacy**

No account, no login, no payment. Your card data — card numbers, balances and
transaction history — never leaves your phone. Exchange rates are fetched once
a day. Ads are served by Google AdMob. The app sends anonymous usage analytics
and crash reports through Google Firebase to help fix problems; these never
include your card number, balance or trips.

**Unofficial — not affiliated with T-money Co., Ltd.**, EB Card Co., KORAIL
Networks, or any Korean transit operator. Card and brand names are used here
only to describe compatibility.

Free, supported by ads. An ad is never shown while a card read is in
progress.
