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.
