Топ-5 лучших декодеров QR-кодов для Android
Далеко не все обращают на это внимание, но вокруг нас тьма QR-кодов. Они почти на каждом рекламном плакате и билбордах, на листовках со специальными предложениями в кафе и ресторанах, на билетах на концерты и любые другие мероприятия. За каждым таким графическим ключом может скрываться важная, полезная и просто интересная информация. Именно поэтому удобная программа для расшифровки QR-кодов должна быть на каждом смартфоне. Тем более, платить даже за самые достойные варианты не придётся.
Kaspersky QR Scanner — фирменный сканер для QR-кодов от «Лаборатории Касперского». Он не просто моментально определяет всё, что зашифровано в графическом ключе, но и проверяет безопасность этого содержимого. Если там ссылка, которая ведёт на потенциально опасный сайт, приложение тут же сообщит об этом и посоветует не переходить на него. Это же касается любого вредоносного контента для операционной системы Android, если злоумышленники решили зашить его в QR-код.
Отдельного внимания заслуживает возможность сканирования QR-кодов на визитках. Если такой попал в ваши руки, приложение автоматически определяет необходимые поля и предлагает заполнить новую запись в контактах. С помощью программы также можно сканировать специальные графические ключи для подключения к Wi-Fi, которыми всё чаще пользуются в офисах, кафе, ресторанах, аэропортах и не только. Она предлагает подключение сразу после сканирования.
В Kaspersky QR Scanner есть отдельное меню с историей QR-кодов, которые вы успели отсканировать. В нём может храниться информация даже о самых старых графических ключах с их детальной расшифровкой.
NeoReader — ещё один простой сканер для QR-кодов. В отличие от предыдущего приложения, это не проверяет безопасность контента, который зашифрован в графическом ключе. Вместо этого у него есть возможность, которая определяет данные, зашифрованные в шрихкоде продукта. Для этого вы можете как просто отсканировать его, так и вбить цифры, записанные под ним. По ним вы сможете узнать дополнительную информацию про изделие.
С помощью приложения можно распознавать QR-коды на фотографиях, сохранённых в память устройства. На время сканирования можно включать вспышку в тёмное время суток, есть журнал с последними расшифровками графических ключей.
QR Droid — одно из самых многофункциональных приложений для работы с QR-кодами. Сразу после запуска оно предлагает отсканировать графический ключ с помощью основной или фронтальной камеры — есть поддержка вспышки, которая пригодится в условиях недостаточного освещения. С помощью приложения также получится сканировать штрихкоды на товарах из магазинов, сохранять их, добавлять вспомогательную о ценах и сравнивать её в разных точках продаж.
Все графические ключи, которые вы уже успели отсканировать, автоматически сохраняются в меню «Мои QR-коды». Здесь информацию на них можно просмотреть повторно, какие-то отметить как избранные, другие удалить. В этом разделе приложения есть кнопка «+», которая предназначена для самостоятельного создания своих QR-кодов. С помощью этой возможности можно создать свою визитку со всей исчерпывающей информацией, поделиться ссылкой или просто текстом.
Сохранённые QR-коды можно перенести в свои умные часы. Это особенно удобно с визитками. Представьте, что вся необходимая бизнес-информация о вас всегда находится на запястье, и вы можете поделиться ей с любым потенциальным партнёром.

QR Code has became very popular in India. Even small vendors accept digital payments, and we use any Payment App (Google Pay, PhonePe, PayTm) to scan a QR Code and pay them easily. And in your next android app project, you might want to add a QR Code Scanner. And that is why I am here with QR Code Reader Android Kotlin Tutorial.
In this tutorial we will use ML Kit to build a QR Code Scanner Application. If you want to know about what exactly we are going to build, then watch the video below.

What is QR Code?
As we already discussed, almost all digital app based payments in India uses QR Code; so I assume you’ve seen a QR Code already. It stands for Quick Response Code. QR Code is a type of Barcode; it is a two dimensional Bar Code. It contains black squares over a white background, and we can put some data in it that can be read by camera.
Below you can see a sample QR Code, and you can use this QR Code to test the application that you will build in this tutorial.
