QR Scanner
Overview
The QR Scanner app is a feature-rich tool designed to scan, decode, and generate matrix barcodes. Developed by P & L Studio, the application is designed to be a lightweight tool for Android devices. While modern Android operating systems often include basic QR scanning in the native camera app, standalone applications like this one must offer advanced, specialized features to remain useful. This utility achieves this by combining standard barcode decoding with advanced document parsing and local database management.
The scanning engine is built for speed and ease of use, automatically recognizing, focusing, and decoding target codes without requiring manual focus or zoom adjustments. The software is highly versatile, supporting all standard 1D and 2D barcode formats—including QR codes, Data Matrix, Aztec, UPC, EAN, and Code 39. When scanning retail barcodes, the app queries online databases to instantly display product details, helping users compare prices while shopping.
The app also features a specialized document reader. By scanning the machine-readable zones (MRZ) on passports and official identification cards, the utility extracts text-based information directly to the device, saving users from manual typing. Additionally, the app includes a secure offline QR code generator, allowing users to create custom codes for website links, Wi-Fi network credentials, contact cards, and text notes. To help users track their scans, the app automatically logs all activities in a local history database. This catalog is stored entirely on the device, allowing users to quickly access previously scanned links or codes without internet access.

Does the scanner require an active internet connection to decode codes?
No, the core scanning and creation engines operate locally on the device. An internet connection is only required when looking up product barcodes or loading external website links.
What formats can the integrated code generator produce?
The built-in generator can create standard high-resolution QR codes containing website links, plain text, Wi-Fi credentials, contact cards, and SMS templates.
How does the passport and ID scanning feature work?
The app uses optical character recognition (OCR) to read the standardized machine-readable zones (MRZ) on the bottom of passports and identity cards, automatically extracting the printed information into digital text.
Can scanned data be exported for business use?
Yes, users can review their complete scan logs in the local history section, which helps manage inventory or track logistics data over time.
Does the app store personal scan data on external cloud servers?
No, scan logs and extracted document data are stored locally on the device's storage. However, the app lacks a direct in-app button to request complete deletion of its cache.
Hot Reviews
The scanning engine works incredibly fast. It recognizes barcodes and QR codes almost instantly, even in low light, without needing to manually adjust the zoom or focus.
While the core scanner is free, the ad placements in recent updates are highly frustrating. Placing ads directly under functional buttons leads to constant accidental clicks on external promotions.
A recent update removed the button to open web links directly inside the app. Users are now forced to copy and paste links manually, adding extra steps to a previously simple process.
