 ## Notes
 
 - The script automatically determines the appropriate QR code version based on the data size.
+- Data is compressed using gzip before being encoded into QR codes to maximize data capacity.
+- Data is then decompressed using gzip after being decoded from QR codes.
 - Error correction level is set to LOW (L) to maximize data capacity.
 - The script handles binary data, including non-printable characters.
 - THe script has a fallback method that (until now) allows for a 100% error free decoding.
