10-20公司平板电脑中独特的设备网络指纹识别

Question

I am trying to implement a QR coding technique at my company. This involves scanning a QR code with an android tablet, and I would like to have certain devices at each station to record information. Is there a very accurate way with javascript or another web framework, which I can edit/create/or log a unique device identifier which can than be read client or server side to log which device this is coming from once the webpage is reached from the QR code?
