Barcode Scanner - Scan & decode barcodes

An app designed to scan various types of barcodes (e.g., on products, Data Matrix, and QR Codes) that may contain URLs, contact information, and more.

Kindly note that this app is no longer supported for updates on Google Play, and no further versions will be released.

Many common concerns and negative reviews are addressed in the following information. 

Frequently Asked Questions

... my contacts?

QR Codes and Data Matrix codes can encode contact information. Upon scanning such a code, you will be prompted to add the contact information to your contacts list. In addition, Barcode Scanner can encode a contact as a QR Code and present it on-screen, so that a friend can point their phone at your screen to transfer that contact. This is why the app requests permission to write and read contacts. They are not used in any other way.

... my browser history and bookmarks?

Just like contacts, you can share a bookmark with a friend by encoding the URL as a QR Code. It is then shown on screen for him or her to scan with their phone. That's the only thing we use them for.

... my SD card?

You can use Barcode Scanner to email a generated QR code or your scan history. To do this, the barcode image / history CSV file must first be written to device storage, which is why the permission is needed. As a bonus, this makes this output available for retrieval from your SD card directly. It is not used for any other purpose.

... my wi-fi settings?

QR codes can encode the user name, password, etc. for a wi-fi network so that you don't have to type them into your phone. To do this, the application needs to be able to change wi-fi settings.

... the Internet?

A few types of scan results will trigger an action to retrieve more information about the result. For example, URL redirectors will be resolved, and web pages will be retrieved up to the title, to give some clue about the destination of the encoded URL before accessing. This needs internet access. Likewise, product and book barcodes will cause a lookup of additional detail about the product or book from internet resources. These can be disabled in settings.

To save time for all users, please review these points first:

Your data is safe as the app only allows sharing contacts, apps, and bookmarks through QR Codes, hence requiring contact permissions. For more details, visit the Developer Website at https://github.com/zxing/zxing/wiki/Frequently-Asked-Questions.

If your device encounters scanning issues, try adjusting device settings to work around any known bugs. Enable all settings and then disable them one by one to identify the essential ones. If problems persist, consider clearing device cache and settings via Android settings.

It is crucial to note that this app has never displayed advertisements and will not do so in the future. Any ads seen are likely caused by third-party malware, which has also falsely accused the app of containing adware while review-bombing it.
