In The static QR code, we can't modify information once it's live which means if any mistake occurs then you need to regenerate a new QR CODE the static code doesn't have expiry once it is generated .once you set QR CODE YOUR WORK DONE it's ideal for store a fixed and sensitive information and scanning activities static QR code not trackable.

 

We can encode the following data on a Static QR code:

• Bitcoin wallet address

 

Dynamic QR code

 

In dynamic, data can only be URL. We can change information as many times as we want because the information is not ingrained into the code itself and we can redirect specific information.
