K vs LED Board

K-Card Reader is a focused Korean transit card balance checker for iPhone. Tap a supported physical KS X 6924 card with NFC to read practical details such as card family, card number, stored balance, issue date, valid-through date, recent trips, and local transaction history where the card exposes it. It is built for travelers, residents, and anyone who wants a quick way to check T-money, EZL/Cashbee, Climate Card, NAMANE, MOIBA, or K-Cash without hunting through station machines. Saved cards stay on your iPhone for fast review. Pro Mode is an optional $2/year subscription that removes ads, unlocks the hex parsing view, and backs up saved cards plus custom card-face images with your iCloud account. This is an unofficial utility and is not affiliated with transport operators, card issuers, or payment networks. It cannot top up cards, issue tickets, validate fares, or modify card data.

Type it, hold it up. The phone becomes an LED panel the whole row can read. Every letter is redrawn dot by dot, so Korean, Japanese, Cyrillic and emoji come out as real lit and unlit LEDs, not as big text. The board - A running message: left, right or still, with speed, letter size and bold - Turn the phone sideways and the board goes up; upright again and it comes back down - Full brightness while it is up, your own level when it closes - Dot size and glow, mirror for holding it behind glass - 30 ready-made messages for concerts, matches, parties, shops and someone you love Signs, new in 2.0 - Up to three short lines held still, each in its own colour - A marquee or double frame round the edge - Sized to fill the screen with no scrolling, for a queue, a fan meeting or the stands The light - A cheer light drawn in dots, with a name under it - Bar, heart, star, ring or orb; steady, pulse, blink, rainbow or wave - Plain shapes in your colours: no group's official light stick is copied - Flash on a tempo from 40 to 200 BPM, with a tap-tempo key (Board Pro) The scoreboard - Two teams, points, period and a running clock, on an LED panel - Quit the app at half time and the score is still on the board Board Pro, paid once Free: the board, signs with two lines, red, white and sky, the bar light, the scoreboard and every ready-made message. Pro adds all colours and your own, square and diamond dots, a third sign line, keeping boards and signs for the next show, the other light shapes and patterns, and the flash. Paid once with your Apple Account. There is no subscription, so there is nothing to cancel. Refunds go through Apple; the app links straight to that page. What it leaves out No ads. No account. No permissions asked. It works with no connection and collects no data; what you keep stays on this phone. Good to know Full brightness uses more battery and can warm the phone; it can be switched off in Settings. Fast flashing is uncomfortable for some people: skip the flash near anyone sensitive to flashing light.
