The QR Codes generated via QR batch are Static.
Static QR Codes are permanent and non-trackable. And they work forever.
Your target content (such as website URL, Vcard details, serial code, or plain text) is encoded directly into the QR Code.
Once you've generated a Static QR Code, you cannot change the encoded content.
Also, the QR Batch cannot provide you any scan analytics (number of scans) for such QR Codes.
So how long will your QR Codes work: forever.
