This is a simple and fast URL QR code scanner suggested use for check-in/check-out of locations in Singapore and for other countries too. Created this app, because I found that most apps in Play Store do not have Chinese instruction display for using the app and most are ads driven, as most older Singaporean are not English educated it would be quite challenging for them to use app that is English-language only and having lots of distracting Ads confusing them even further.
