Limitations

In this section, we will discuss the limitations of OpenAttestation credentials.

QR Code

In some cases, it might be beneficial for the data of credentials to be fully contained inside machine-readable content, such as QR Code.

As we have seen previously, OpenAttestation credentials are naturally verbose. During wrapping, we add a salt in front of each value. Because of this process, the number of data that an OpenAttestation credential can hold to fit inside a QR Code is limited.

We made a benchmark to give you some indications of the maximum data you can add to your credentials before it exceeds a QR Code capacity limit.
