Building a URL Redirector in Python for Dynamic QR Codes
· 4 min read
If you print 1,000 posters with a QR code and the website URL changes next week, a "Static" QR code becomes a pile of wasted paper. The solution is a Dynamic QR code.
Instead of encoding your final destination (like myshop.com/promo-january), you encode a "Short URL" that you control (like myqr.link/offer). When a user scans it, your server looks up where offer should go today and redirects them instantly.
