Ingestible radio frequency identification (RFID) tags are disclosed. A system embodiment includes, but is not limited to, an RFID tag including a flexible substrate foldable between a planar configuration and a tubular configuration, a conductive element disposed on the flexible substrate, and an RFID tag chip electrically coupled with the conductive element; a capsule structured and dimensioned for ingestion by a biological subject, the capsule including a shell structured and dimensioned to enclose a medication for the biological subject simultaneously with the RFID tag when the flexible substrate is in the tubular configuration, but not when the flexible substrate is in the planar configuration; and a pH switch structure coupled to an exterior surface of the capsule, the pH switch configured to deactivate the RFID tag in a first configuration and to permit activation of the RFID tag in a second configuration within the biological subject.
