Plenty of people will tell you that mobile ID checks are a lottery: sometimes the photo sails through, sometimes it bounces back three times and you spend the evening reshooting your driving licence on the kitchen table. The lottery theory is wrong. In almost every failed case I have seen, the problem is not the document, the lighting or the reviewer’s mood. It is the upload path. If you pick a file from your camera roll instead of using the camera, you hand the system a compressed, resized image that automated checks struggle to read, and the approval queue slows down accordingly. This tutorial walks through the process properly, using Casushi as the worked example, because the steps map onto most regulated operators.
Why the “just upload a screenshot” advice fails on phones
The myth goes like this: your phone camera is fiddly, so take a screenshot or pick an existing photo from your gallery, and the casino’s system will handle the rest. That advice circulates because it works just often enough to seem true. What actually happens is that gallery images arrive after the operating system has already re-encoded them. An iPhone shooting in HEIC converts to JPEG on export, and an Android handset set to save space may store a 12MP capture as a 2MB file. Edges soften, microprint blurs, and the automated document check flags the image for manual review.
Manual review is not a rejection, but it adds hours or days. The camera route inside the app or browser skips that compression step entirely. The capture goes straight into the verification pipeline at full resolution, which is why the “Take Photo” button exists in the first place. It is not decoration.
What the verification step is actually checking
Three things: that the document is genuine, that it belongs to the account holder, and that the name and date of birth match what you entered at registration. A fourth check covers address, usually via a utility bill or bank statement dated within the last three months. None of this requires a professional studio. It requires a sharp, uncropped, glare-free image where all four corners of the document sit inside the frame. That is the whole job.
One more myth worth killing: some players believe a selfie with the document is stronger evidence. It is not, and it often makes things worse because the angle distorts the text. Follow the prompts exactly and nothing more.
The step-by-step photo process, start to finish
These steps assume you have already registered and made a first deposit. Verification can be triggered at deposit, at withdrawal, or by a random check. Casushi account holders on iPhone and Android follow the same flow, though the buttons sit in slightly different places depending on whether you are in the app or a mobile browser.
Step 1: log in on mobile and open Account > Verify. Do this on the phone you will use for the photo, not on a desktop. Logging in on mobile first means the session is tied to the device camera permissions, and the “Take Photo” option appears as a live button rather than a fallback. If you start on a laptop and try to finish on your phone, you will often end up in a file picker instead.
Step 2: tap “Take Photo”, not “Choose File”. This is the single most important instruction in this article. The “Choose File” option opens your gallery or file manager, and everything in there has already been through at least one compression pass. “Take Photo” opens the native camera and sends the raw capture into the verification queue. On an iPhone this launches the standard iOS camera interface; on Android it opens whichever camera app is set as default, usually the manufacturer’s own or Google Camera.
Step 3: fit all four corners of the document inside the frame. Lay the document flat on a dark, plain surface. Avoid glass tables, which reflect overhead lights, and avoid patterned tablecloths, which confuse edge detection. Hold the phone parallel to the document, roughly 20 to 30 centimetres away, and wait for the focus to lock before tapping the shutter. All four corners must be visible with a small margin around each one. Cropping a corner to fit the frame is the second most common cause of rejection after file upload.
Step 4: review the preview and submit. The app will show you the captured image before sending. Zoom in on the document number and check it is legible. If it is not, retake rather than submit, because a blurry submission still counts as an attempt and some operators limit how many you can make in a day. Once you are satisfied, tap submit and leave the app open until you see the confirmation screen. Closing the app mid-upload is a quiet killer.
Doing the same thing on the Casushi mobile site
If you are playing through the browser rather than the app, the flow is nearly identical, but the camera permission prompt behaves differently. Chrome on Android will ask once whether the site may use your camera; grant it, and the “Take Photo” button will work as expected. On Safari for iPhone and iPad, the permission prompt appears each session unless you have allowed the site permanently. If the camera button appears greyed out, check Settings > Safari > Camera and confirm the site is not blocked.
The responsive layout on the Casushi mobile site detects your screen dimensions automatically, so the document frame adjusts to fit your handset. On a small phone in portrait, the guidance overlay may look cramped; rotating to landscape gives you a wider capture area and usually produces a better shot of a passport or ID card. Apple users who prefer the native experience can download the Casushi app from the App Store, where the camera step is embedded in the app itself and the permission is handled once at install.
Device-specific snags worth knowing before you start
Android users access the Casushi site through a mobile browser, and that is the only official route on that platform. Casushi does not publish a standalone Android APK file, so any site offering one is not the real thing, whatever the download page claims. The absence of an APK is not a limitation; it is a security decision, and it means your verification goes through the same browser-based pipeline as everything else. Add the site to your home screen via Chrome’s menu and you get a shortcut that behaves much like an app without the sideloading risk.
On iOS, the Casushi app supports Face ID logins, which speeds up the repeated logins you will do while chasing a verification query. It also means you can leave the app and return without retyping a password, which matters when a reviewer asks for a second document and you need to get back in quickly. Push notifications from the app will tell you the moment a document is approved or rejected, so you are not refreshing the account page every hour.
Two hardware quirks catch people out. First, some Android phones default to a wide-angle or macro lens when the camera is opened from a browser, which distorts the document edges. If your preview looks bowed, switch lenses manually before capturing. Second, iPhone users with a case that covers the lens or a smudged camera will produce hazy images without realising it. A quick wipe with a cloth solves more rejections than any setting change.
Lighting, glare and the reflective document problem
Glare is the third big cause of failed checks, and it is almost always caused by an overhead light bouncing off a laminated surface. Move to a spot with indirect daylight, or angle the document slightly away from the light source. Do not use the camera flash, which creates a bright hotspot that wipes out a chunk of the text. If you are verifying at night, a lamp positioned to the side rather than above works far better than ceiling lighting.
Driving licences with holographic overlays are the worst offenders. Tilt the document a few degrees until the hologram stops reflecting into the lens. The reviewer needs to see the printed details, not a rainbow.
What happens after you submit, and how to avoid a second round
Most mobile submissions at a regulated operator are reviewed within a few hours, and often within minutes if the automated check passes cleanly. The camera route is faster precisely because the image quality clears the automated threshold more often. A gallery upload that fails the automated check lands in a manual queue that can take 24 to 48 hours depending on volume. That difference is the entire reason this tutorial exists.
If you are asked for proof of address, apply the same rules: camera, not file picker, all four corners, no glare. Bank statements downloaded as PDFs are a common trap. A PDF screenshot taken on your phone will be compressed; instead, open the PDF on your phone, display the relevant page, and use the casino’s “Take Photo” option to photograph the screen at full brightness. It sounds crude, but it produces a sharper image than most screenshot workflows.
The Casushi app cashier manages payments in the same place, and verification status sits alongside deposit and withdrawal limits. Once approved, the badge changes and withdrawals process without further friction. Keep an eye on the cashier screen after submitting, because some operators post the approval there before sending an email or push notification.
One last myth: that a rejected document means your account is flagged. It does not. Rejections are routine, especially for first-time mobile submissions, and a clean retake clears them without penalty. The only thing that damages your standing is submitting the same blurry image repeatedly instead of following the camera steps.
Before you start, do three things: update your phone’s operating system so camera permissions behave predictably, clear the lens, and find a flat surface with side lighting. Then log in on mobile, go to Account > Verify, tap “Take Photo” rather than “Choose File”, fit all four corners inside the frame with a small margin, check the preview for legibility, and submit without closing the app. That sequence is the difference between a check that clears in minutes and one that drags into next week. Note that this website operates as an information page only and does not process registrations or verification itself; the steps above are for use on the operator’s own app or mobile site. For responsible play, the Casushi mobile site offers deposit limits, session reminders and self-exclusion tools, all accessible from the same account menu where verification lives.
