About

Scan2Ring

Read full description

Scan2Ring allows you to create QR code bells which can be rung by scanning QR codes followed by tapping on the ring button on a webpage. Simply create one or more bells and print or share the related QR codes. You can also combine multiple bells into a bell group, so a single QR code lets you choose which bell to ring — handy for cutting down on clutter when you'd otherwise need a separate code on display for each one. You can have your bells on multiple devices and you can add your family members, housemates, colleagues, etc. to your bells so that they can also hear the bells on their devices. You or your associates can interact with a bell ringer with or without video. A person ringing a bell (scanning a QR code) does not need the app – they can use their usual means for scanning a QR code, e.g., camera app. Key features: - Permanent free plan available - QR code video bells - Bell groups (one QR code reveals multiple bells) - Hygienic - Environmentally sustainable - Easy installation - No extra hardware - No power sockets - No batteries - No cables - No drilling Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
