Extends the applied pi-calculus with location and start/stop timer actions to model distance‑bounding behavior, defines and orders five+ formal security properties, and introduces uncompromised distance bounding as a new, practically relevant property for payment cards and car fobs. Compiles models into the ProVerif tool for automated checking, applies this to MasterCard and an NXP‑patent protocol, and finds new relay/hijacking attacks including a practical weakness if NXP uses a shared key instead of per‑device keys.
