Techniques for negotiation techniques for mobile personal trusted device financial transactions are provided. A user of a mobile personal trusted device sets user preferences that define the user's preferred parameters for conducting financial transactions. A merchant sets merchant preferences that define the merchant's preferred parameters for conducting financial transactions. When a financial transaction is initiated, a user preference and a merchant preferences are accessed. A negotiated preference is generated that accommodates both the user preference and the merchant preference. If the user preference and the merchant preference are not mutually exclusive, the negotiated preference attempts to satisfy both preferences. If the user preference and the merchant preference are mutually exclusive, the negotiated preference satisfies at least one of the two preferences based on which of the two preferences has a higher priority. The financial transaction is conducted based on the negotiated preference.
