About this app

QR Codes become more and more important. In some areas they have even replaced the traditional barcode. A QR Code is able to store up to seven thousand characters and therefore is qualified for more complex content, e.g. vCards. Hence nowadays QR Codes can nowadays be found on nearly every advertisement poster and animate the user to scan it with his smartphone. Thus, it is no longer necessary take a hand written note, it is enough to scan the QR Code. Correspondingly, there are already many QR Code scanner apps available in the Google Play Store. It belongs to the Privacy Friendly Apps group developed by the research group SECUSO at Technische Universität Darmstadt. More information can be found an secuso.org/pfa

Our Privacy Friendly QR Scanner App differs with respect to two aspects:

1. The Privacy Friendly QR Scanner App only requires the minimum amount of permissions, namely:
Most of the QR Code scanner apps available in the Google Play Store need several permissions on top of the ones needed: e.g. reading contacts or your call log and retrieving data from the Internet. Most of these requirements are not necessary for the functionality they actually are supposed to provide.

2. The Privacy Friendly QR Scanner App supports its users in detecting malicious links: QR Codes provide new possibilities for an attacker, as QR Codes can contain malicious links, i.e. links to phishing webpages or webpages from which malware would automatically be downloaded. Therefore it is important to carefully check the link before accessing the corresponding webpage. Since it is difficult for the user to spot malicious links, the Privacy friendly QR Scanner App supports the user by highlighting the domain (e.g. in that case for https://www.secuso.org, secuso.org would be highlighted). To avoid not checking the link and in particular the highlighted domain carefully, the app provides information about possible fraud and its users need to confirm that they checked the link and it is trustworthy. Note, the information shown after scanning an URL based QR Code is not customized for every URL. Hence, it should be considered as an advice for the user how to behave in general.

The Privacy Friendly QR Scanner App supports most of the usual qr code types. Bar codes and other widely used codes are also supported.

The app belongs to the group of privacy friendly apps, that are developed by the SECUSO research group. More information can be found at https://secuso.org/pfa

Suits my needs perfectly. I love that it does nothing with the scanned content before I have the chance to check it. It gives me the control. Often I just want to scan something like a serial number from a bar code and copy to the clipboard - it can do that too. The only problem is that it has tends to have difficulty focussing the camera and detecting the code. I sometimes need to adjust the position and/or distance, rarely I need a second attempt. But it always gets there in the end.

It scans codes, and lets you save them. But you can't do much with the saved codes. It stores the version, error correction level, and mask, but doesn't display them to the user. You also can't bring up the saved codes full screen for somebody to scan. Generator can't do text QR codes, and crashes if I try to store a generated code.

Best free scanner l've seen. Scans bar codes and QR codes well on my Android 10. Lots of options for dealing with results (copy/share/search). This is v. 4.0.1.
