Took about 20 minutes to get the passport scanned, chip read which required research and lastly picture taken. By the time I got it working, I was at the front of the line. Maybe useful for next time ### 1/5 — Does not work for EU passport *2026-06-15, version 1.0.12* Really bad app unfortunately. Does not work for EU passport ### 1/5 — So bad *2026-06-14, version 1.0.12* Made with stupid, never go through the scan passport part ### 1/5 — Most painful app ever used *2026-06-14, version 1.0.12* It is almost unusable. I do not know why it is put out for others to use. I cannot get the chip scanned, very frustrated. It is the opposite of “smart”. ### 1/5 — Absolutely trash app *2026-06-09* Extremely difficult to scan and read passport. Waste of time. Lag and reload issues. ### 1/5 — Doesn’t Work Well *2026-05-28, version 1.0.12* After registering and scanning my passport, I couldn’t get past the boarding pass registration. Even with a clear QR code it didn’t work. Useless app! ### 1/5 — Not helpful *2026-05-27, version 1.0.12* I am trying to set this up and although I pressed English the app is in Korean and I can’t understand what I’m doing!! ### 1/5 — Not working!! *2026-05-27* Tried for a whole hour while waiting in line. Ran my battery down thinking it’s my fault! It just doesn’t work. Scan for chip never works! What a terrible app. Why even bother putting up signs everywhere. Invest in better working technology! ### 1/5 — never scan *2026-05-24* can never scan. Garbage! ### 2/5 — Garbage *2026-05-23, version 1.0.12* Read the comments for US older passports. The NFC is on back page inside cover. ### 1/5 — BOO *2026-05-17, version 1.0.12* Chip doesn’t even scan man. ### 1/5 — Nfc scan fails *2026-05-13, version 1.0.12* Not working as the nfc scan keeps failing ### 1/5 — Doesn’t work *2026-05-13* Useless ### 1/5 — 难用 *2026-05-02* 机场效率低，App也难用 ### 1/5 — worst app ever *2026-05-01, version 1.0.12* super laggy and buggy, not to mention the language switch didnt actually work the first time and i had to toggle it multiple times for it to work. also the fact that i had to finangle the orientation of my passport for over 5 minutes with only the help of other reviews is honestly ridiculous. ### 1/5 — 쓰레기 *2026-04-27, version 1.0.12* 이딴걸 쓰라고 만들었냐 ㅎㅎ ## Most critical reviews (10 lowest-rated) ### 1/5 — 星1もつけたくありません。 *2026-08-10* 登録しようとアプリインストールしましたが、どのボタンタップしてもグルグルグルグル読み込みが終わらない。読み込みに時間かかりすぎ。 せっかく登録してスムーズに出国できると思ったら、1個ボタン押す事に読み込みが長すぎて登録に時間かかるとかふざけてますよね。 アンインストールします。もう使いません。 こんなゴミアプリなら 登録する手間<並ぶ となるので並んだ方がいいです。 ### 1/5 — Garbage *2026-08-08, version 1.0.12* Cannot read my EU passport …. Useless app , shameful for Korea who a leader in technology… an African 10 years old can make a working app, but you not capable… ### 1/5 — Terrible app *2026-07-21, version 1.0.12* This app is useless. Does not work, does not scan us passport and does not work on IOS Don’t bother with it not needed. ### 1/5 — Terrible and Slow *2026-07-20, version 1.0.12* Nothing ever loads ### 1/5 — Complete waste of time *2026-07-19, version 1.0.12* this app sucks so much ### 1/5 — Never works *2026-07-11, version 1.0.12* This app never works and need to be seriously from ground up. It baffles me that they are not iterating on this given dismal reviews and terrible user experience ### 1/5 — Terrible app *2026-07-08* Doesn’t scan the chip via NFC ### 1/5 — App crashed after NFC scan *2026-06-24, version 1.0.12* Bad experience, bad app!!! ### 1/5 — App will fight you every step of the way *2026-06-23, version 1.0.12* This is not a convenient app to use. The load times take forever, the phone tells you to move around your iPhone when scanning the passport and then tells you it couldn’t scan your passport because you moved your phone. QR code scan for registering your boarding pass is janky and hasn’t worked for me either. Would rather just have to show my passport and boarding pass at the airport at this point ### 1/5 — 登録は出来たけど *2026-06-19* 一昨年くらいに韓国行った時にスムーズそうなのを見て登録した。 読み込まないというのを見ていたから案外スッと読み込めて拍子抜けしたが次からは楽だな〜なんて思い、今年。 韓国行くし使用前に確認しておこうと思ったら、顔認証で入れたものの永遠に白画面にくるくる…使えなくなっていた。 これだけ低評価になってるのに直さないんだな…。 ## Most praised reviews (10 highest-rated) ### 5/5 — 잘만되는데 *2026-08-12* 50번 시도하면서 안될때까지 이것만 붙잡고 있느라 비행기 놓친 사람은 본인 지능을 의심해야할 듯 안되면 그냥 일반 출국게이트로 가야지 뭐하냐? ㅋㅋㅋ 어이가 없어서 리뷰남김 ### 5/5 — Smart Pass (Korea) – My Experience & Tips for Scanning a U.S. Passport *2026-07-25, version 1.0.12* I had a good experience using the Smart Pass app. Overall, I didn’t have any major issues with it. The only part that took me a few tries was scanning the NFC chip in my U.S. passport with my iPhone. Once I figured out the correct position, everything worked perfectly. Here are a few tips that may save you some time. iPhone Users Hold your passport in your left hand with the inside back cover open. With your right hand, hold your iPhone horizontally and press the top of the phone firmly against the back of the passport. The NFC antenna on iPhones is located near the top of the device. Don’t move the phone. Hold it steady and wait for the check mark to appear. Once you see the check mark, continue with the remaining steps and you’re done. Android Users The process is very similar. Open the passport to the inside back cover and place the back of your Android phone against the back of the passport. The NFC antenna is usually located on the back of most Android phones (though the exact location may vary by model). Again, don’t move the phone. Hold it steady until the check mark appears, then continue with the rest of the setup. One Recommendation For both iPhone and Android users, I highly recommend removing your phone case before scanning. It may help the NFC connection, especially if you have a thicker case. One Small Thing I Noticed During the initial setup, the app asks which language you’d like to use. I selected English and continued through the setup. However, when the main screen loaded, the app was still in Korean. It wasn’t a big deal. I simply went into Settings, selected English again, saved it, and the entire app switched to English. Overall Once I got past the passport scan, the rest of the process was quick, straightforward, and easy to follow. As soon as I completed the setup, my boarding information appeared automatically without any problems. I hope these tips help someone else avoid the trial and error I went through. Good luck, and safe travels! 😊 ### 5/5 — Положительный отзыв *2026-06-09* Зарегестрировал российский паспорт моментально. Во время сканирования NFC на паспорте не шевелите телефоном, просто положите телефон на метку и не трогайте пока не появится галочка. ### 5/5 — お勧め！4分で登録完了。シニア世代でも登録簡単。 *2026-05-23* ①パスポート写真→明るい所だと1回で読み込む終了 ②パスポートICチップ( パスポートの硬いページにICチップ有り )→硬いページだけスマホを置けば勝手に読み込むでくれる ③本人写真→すぐに認証終了眼を開いている写真と眼を閉じてる写真 ④後は搭乗券はチェックインした時に登録します ### 5/5 — READ THIS FOR US CITIZENS *2025-09-30* For the passport scan (iPhone) 1. Take off phone case 2. Open passport and flip all the way to the back COVER 3. When prompted to scan, hold the top of your iPhone in the middle of the INSIDE back cover until you see the text “reading passport” 4. Hold until successful ### 5/5 — 너무 편함 *2025-09-28* 등록 쉽고 간편하게 잘만 했고 공항에서 간편하게 금방 들어갔어요 ### 5/5 — 난 잘 되던데? *2025-09-19* 이런거 있는지 몰랐다가 공항에서 바로 앱 설치하고 사용하는데까지 5 분 도 안걸림. 그 사이에 업데이트 됬을지도? ### 5/5 — なんとなく *2025-09-11* ‘17年発行のパスポートでも出来た。チケット(Agoda予約のJEJU航空)もセルフチェックインした時点で自動登録されていた。しかし保安検査に入るまで優先されるだけなので、保安検査とイミグレは通常通りでメリットが薄い。 ### 5/5 — 핸드폰번호나 카드없으면 등록불가 *2025-07-31, version 1.0.6* 아직 미성년자라 전번이랑 카드없는데 본인인증못함 ### 5/5 — iPhone12,新パスポート *2025-06-27* 日本旧パスポートは読み取り出来ても顔認証でダメになったりして出来ませんでしたが 2025年の新パスポート後はきちんと利用できます。 長蛇の列に並ばなくてもいいのとっても快適でした！ --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
