Is my camera feed uploaded anywhere?

No. The video stream stays on your device: frames are decoded locally in your browser by JavaScript. Nothing is recorded, stored or uploaded — the scanner works entirely client-side.

Why does the scanner ask for camera permission?

Reading a QR code with your camera requires access to the video stream. The browser asks for your approval first and shows it in the address bar; you can revoke it at any time and nothing is ever sent over the network.

The QR code contains a link — is it safe to open?

Not always. Scanning shows you the raw destination before you click, which is exactly why reading QR codes on desktop first is safer than tapping blind links. Check the URL carefully — look-alike domains are a common phishing trick.

Can I decode a QR code from an image instead of the camera?

Yes — drop a screenshot or photo of the code into the image decoder below and it is read locally with the same privacy rule. PNG, JPEG, WebP and GIF all work, as long as the code is sharp and fully visible.

QR Code Scanner

E kuhikuhi i kāu pahupaʻikiʻi ma kahi QR code - a waiho i kahi kiʻi o kekahi - a heluhelu koke i kāna ʻike: nā loulou, nā hōʻoia Wi-Fi, nā pilina, nā kikoʻī uku. Hoʻololi ʻia nā mea a pau i kāu polokalamu kele pūnaewele: ʻaʻohe mea i haʻalele i kāu kelepona.

E waiho i kahi kiʻi ma ʻaneʻi a i ʻole kaomi e koho i kahi faila

PNG, JPEG, WebP, GIF — hoʻokaʻawale ʻia me ka jsQR, ʻaʻohe mea e waiho i kāu kelepona

E nānā i nā code QR me ka hoʻokomo ʻole ʻana i kahi polokalamu

ʻO ka hapa nui o nā kelepona i kēia manawa e hoʻokaʻawale i nā code QR mai ke kāmela i kūkulu ʻia, akā ma ke kamepiula a i ʻole ka pākaukau pono ʻoe i kahi hāmeʻa - a ʻo ka hapa nui o nā scanner pūnaewele e hoʻouka i kāu mau kiʻi paʻi kiʻi a i ʻole nā kiʻi i kā lākou mau kikowaena. ʻAʻole kēia: he waihona JavaScript liʻiliʻi ka decoder (jsQR) i hoʻoili ʻia i kāu polokalamu kele pūnaewele, a nānā ʻia kēlā me kēia kiʻi wikiō ma kāu kelepona.

He aha nā QR code maʻamau

HKH - hōʻike ka scanner i ka huakaʻi holoʻokoʻa ma mua o kou wehe ʻana, no laila hiki iā ʻoe ke ʻike i nā kikowaena like.
Nā hōʻoia Wi-Fi - hōʻike ʻia ma ka maʻamau WIFI:S:…;P:…; format, mākaukau e paʻi i loko o kekahi mea hana.
Kāleka pili (vCard) - nā inoa, nā helu kelepona a me nā leka uila ma ke ʻano he kikokikona maʻalahi.
Nā uku, nā loulou app, nā tikiki hanana - hiki ke hoʻopaʻa ʻia kekahi uku i ka QR encoder.

Noho palekana: ʻO ka QR code he loulou wale nō i paʻi ʻia e kekahi. E mālama i nā URL i hoʻokaʻawale ʻia e like me nā loulou ʻike ʻole - e heluhelu pono iā lākou ma mua o ka wehe ʻana, ʻoi aku ka nui o ka wā e noi ai lākou i nā loina a i ʻole nā uku.

Makemake ʻoe i kahi ʻaoʻao i hoʻolaʻa ʻia? ʻO ka Heluhelu helu QR hāʻawi kiʻi decoding ma kona iho, a me ka QR code generator hana i nā code ma ke ʻano pilikino like.

FAQ

Nīnau QR scanner

Ua hoʻouka ʻia kaʻu ʻai pahupaʻikiʻi ma nā wahi ʻē aʻe?

ʻAʻole. Noho ke kahawai wikiō ma kāu hāmeʻa: ua unuhi ʻia nā kiʻi ma kāu polokalamu kele pūnaewele e JavaScript. ʻAʻohe mea i hoʻopaʻa ʻia, mālama ʻia a hoʻouka ʻia - ke hana holoʻokoʻa ka scanner ma ka ʻaoʻao o ka mea kūʻai aku.

No ke aha e noi ai ka scanner i ka ʻae kamera?

Pono ka heluhelu ʻana i kahi QR code me kāu pahupaʻikiʻi e komo i ke kahawai wikiō. Nīnau ka polokalamu kele i kāu ʻae mua a hōʻike iā ia ma ka pahu helu; hiki iā ʻoe ke hoʻopau iā ia i kēlā me kēia manawa a ʻaʻohe mea i hoʻouna ʻia ma luna o ka pūnaewele.

Loaʻa i ka QR code kahi loulou - palekana paha ke wehe?

ʻAʻole mau. Hōʻike ka nānā ʻana iā ʻoe i kahi huakaʻi ma mua o kou kaomi ʻana, ʻo ia ke kumu ʻoi aku ka palekana o ka heluhelu ʻana i nā code QR ma ka pākaukau ma mua o ke kaomi ʻana i nā loulou makapō. E nānā pono i ka HKH - ʻo nā kāhuna like-like he hana phishing maʻamau.

Hiki iaʻu ke hoʻokaʻawale i ka QR code mai kahi kiʻi ma mua o ke kāmela?

ʻAe — hoʻokuʻu i kahi kiʻi paʻi kiʻi a i ʻole kiʻi o ke code i loko o ka decoder kiʻi ma luna a heluhelu ʻia ma ka ʻāina me ke kānāwai pilikino like. ʻO PNG, JPEG, WebP a me GIF nā hana a pau, ʻoiai ʻoi aku ka ʻoi o ke code a ʻike pono ʻia.
