What documents are needed for RFID?

Excuse me, could you please clarify what specific documents are typically required for RFID implementation or adoption? Are you referring to regulatory compliance documents, technical specifications, contracts with suppliers, or perhaps something else entirely? It would be helpful if you could provide a bit more context or detail on the type of RFID system you're considering, as the necessary documents can vary depending on the application and industry. Thank you for your time.
