Vendors: What do I do with the TC String?

What do I do with the TC String?

According to policies of the Transparency and Consent Framework, a vendor may choose not to transmit data to another vendor for any reason, but a vendor must not transmit data to another vendor without a justified basis for relying on that vendor’s legal basis for processing the personal data.

If a vendor has or obtains personal data and has no legal basis for the access to and
processing of that data, the vendor should quickly cease collection and storage of the data and
refrain from passing the data on to other parties, even if those parties have a legal basis.
