RFID-based methods

摘要

A cell phone is used to sense information, such as digital watermark data or RF ID data, from a physical object (e.g., a product package). Thereafter, a user of the cell phone engages in a transaction (e.g., downloading content from the internet). Normally, a charge may be assessed for this transaction. However, the user is spared this charge by reason of said earlier sensing of information from the physical object. A great number of other features and arrangements are also detailed.
