Our regular review items allow for us to hard-program the cards with your review URL, while the dynamic cards come with our free management software. The difference is the regular review items are stuck with your review URL, if you want to change you'll have to reprogram the Tap Tag. If you add a QR it will not be changeable in the future. The Dynamic Tap Tags can be changed remotely from your dashboard, in addition to a few other features like printing your QR code, tech support, and an optional upgrade to Review Filtration.
