I have a mobile website builder and I need to implement a feature that can track device IDs. Currently we are assigning DEVICE ID”S to each phone from the URL..but this can be unreliable as you can imagine. We need to track each device ID so we know which coupons the device is redeeming. we already have the system set up but looking how we can capture some sort of stable device ID via HTML or when they click the REDEEM button for the coupon.
