A device useful for oral drug delivery device consisting of: (a) a capsule, tablet or pill designed to disperse in the gastrointestinal system; (b) an RFID tag positioned in the capsule, tablet or pill, the RFID tag comprising an antenna; (c) an object selected from the group consisting of a magnet,
A device useful for oral drug delivery device consisting of: (a) a capsule, tablet or pill designed to disperse in the gastrointestinal system; (b) an RFID tag positioned in the capsule, tablet or pill, the RFID tag comprising an antenna; (c) an object selected from the group consisting of a magnet, a ferromagnetic object, a ferrite object and an electromagnetic shielding object positioned within, over or adjacent the antenna of the RFID tag to alter the antenna characteristics of the RFID tag so that if the RFID tag is interrogated before the capsule, tablet or pill disperses in the gastrointestinal system, the response of the RFID tag is sufficiently altered or attenuated to determine that the capsule, tablet or pill has not dispersed in the gastrointestinal system and so that if the RFID tag is interrogated after the capsule, tablet or pill has dispersed in the gastrointestinal system, the object separates from the RFID tag so that the response of the RFID tag is sufficiently detectable to determine that the capsule, tablet or pill has dispersed in the gastrointestinal system. Alternatively, a switch can be used to signal ingestion of the device, and change the response of the device.

What is claimed is: 1. A device useful for oral drug delivery, comprising: (a) a capsule, tablet or pill which will disperse in the gastrointestinal system; (b) an RFID tag positioned in the capsule, tablet or pill, the RFID tag comprising an antenna; (c) an object selected from the group consistin
What is claimed is: 1. A device useful for oral drug delivery, comprising: (a) a capsule, tablet or pill which will disperse in the gastrointestinal system; (b) an RFID tag positioned in the capsule, tablet or pill, the RFID tag comprising an antenna; (c) an object selected from the group consisting of a magnet, a ferromagnetic object, a ferrite object and an electromagnetic shielding object, the object positioned within, over or adjacent the antenna of the RFID tag to alter the antenna characteristics of the RFID tag so that if the RFID tag is interrogated before the capsule, tablet or pill disperses in the gastrointestinal system, the response of the RFID tag is sufficiently altered or attenuated to determine that the capsule, tablet or pill has not dispersed in the gastrointestinal system and so that if the RFID tag is interrogated after the capsule, tablet or pill has dispersed in the gastrointestinal system, the object separates from the RFID tag so that the response of the RFID tag is sufficiently detectable to determine that the capsule, tablet or pill has dispersed in the gastrointestinal system. 2. The device of claim 1, wherein the object of element (c) disintegrates in the gastrointestinal system. 3. The device of claim 1, wherein the object of element (c) separates from the RFID tag in the gastrointestinal system. 4. The device of claim 1, wherein the RFID tag is selected from the group consisting of an active RFID tag and a passive RFID tag. 5. The device of claim 4, further comprising a drug formulation positioned in the tablet, pill or capsule. 6. A device useful for oral drug delivery, comprising: (a) a tablet, pill or capsule designed to disperse in the gastrointestinal system; (b) an RFID tag positioned in the tablet, pill or capsule, the RFID tag comprising a switch, the switch turning on or off in response to conditions in the gastrointestinal system so that if the RFID tag is interrogated before the tablet, pill or capsule disperses in the gastrointestinal system, the response of the RFID tag signifies that the capsule has not dispersed in the gastrointestinal system and so that if the RFID tag is interrogated after the tablet, pill or capsule disperses in the gastrointestinal system, the response of the RFID tag signifies that the tablet, pill or capsule has dispersed in the gastrointestinal system. 7. The device of claim 6, wherein the RFID tag is selected from the group consisting of an active RFID tag and a passive RFID tag. 8. The device of claim 7 further comprising a drug formulation positioned in the tablet, pill or capsule. 9. A device useful for oral drug delivery, comprising: (a) a capsule, tablet or pill designed to disperse in the gastrointestinal system; (b) a first non-anti-collision RFID tag positioned in the capsule; (c) a second non-anti-collision RFID tag positioned in the capsule, so that if the RFID tags are interrogated by an RFID reader before the capsule, tablet or pill disperses in the gastrointestinal system, the response of the RFID tags collide and so that after the dispersible material of the capsule has dispersed in the gastrointestinal system thereby allowing the first and second non-anti-collision tags to separate from each other, then the response of the RFID tags is sufficiently different from each other to determine that the capsule has dispersed in the gastrointestinal system. 10. The device of claim 9, wherein the RFID tag is selected from the group consisting of an active RFID tag and a passive RFID tag. 11. The device of claim 10, further comprising a drug formulation positioned in the tablet, pill or capsule.
