The image contains two nested barcodes.
The *QR code* can be analyzed simply cutting the code portion and analyzing it.

Decoding it will give the following.
```137:64:137:154:171:146:63:175```
Decoding from octal representation to ASCII will give the following.
```_4_lyf3}```
Then you have to cut the *Aztec code* from the global one.

Decoding it will give the following.
```414f54577b6234726330643373```
Decoding from hexadecimal representation to ASCII will give the following.
```AOTW{b4rc0d3s```
Putting everything together will give you the flag.
```AOTW{b4rc0d3s_4_lyf3}```
