There is no such thing as “dynamic qr” codes. Once something is printed it’s permananent.
Use a url shortener on a domain you own if you really want the ability to change the end point URL and track usage by placements.
Attaching hard-coded marketing items to a service you don’t know will be around in a year is about as stupid as it gets if you’re planning on putting your QR codes on long term printed materials or signage of any sort.
