When Compliance Ledgers Meet the Circular Exchange

A battery serial born in an Annex XIII ledger should not disappear into a scrap broker's notebook at end of life. PassCell keeps one serial on one grid from factory commit through marketplace listing — manufacturing data untouched, exchange fields layered separately.

Data separation

Listing on the exchange updates marketplace columns only. Operator emails, factory coordinates, and restricted passport fields never appear on buyer cards.

Commercial lifetime

Compliance unlocks EU market access. Exchange unlocks retirement revenue. Both attach to the same passport UID recyclers can audit for EPR.
