No special equipment is needed – one of the benefits of CVS is that it leverages devices you likely already have. Any modern smartphone or tablet with a camera can scan QR codes. Most phone cameras today will recognize a QR code automatically and prompt to open the encoded link (which would be the CVS record URL). Alternatively, you could use any free QR scanner app if preferred, but it’s not required. There’s no proprietary scanner or handheld device you must buy, and you don’t need to install a dedicated CVS mobile app. The system is web-based, so scanning the code essentially just opens a secure webpage in your phone’s browser, showing the credential info. This makes it very accessible – whether it’s a project manager with an iPhone or a safety inspector with an Android tablet, they can all scan and view the data instantly. Even if you’re in a remote area without consistent internet, as long as the device can get a cell signal at the moment of scan, it will work. By avoiding specialized hardware, CVS keeps things simple and cost-effective: your existing phones and tablets are all you need to verify training in the field.
