8. A system as recited in claim 7 wherein the sensor comprises a Bluetooth Low Energy (BLE) device.

9. A system as recited in claim 7 wherein the sensor continuously measures and communicates and wirelessly transmits the environmental conditions to an external device to update or analyze the measured environmental conditions throughout a supply chain from manufacturing to distribution.

10. A system as recited in claim 7 wherein the sensor detects, during storage or shipment, that the sensor measurements deviate from the product or item environmental specifications and calculates the impact to the expiration date on the product or item and wirelessly updates the expiration date and/or an estimated time of validity stored in the memory of the product or item tag.

11. A system as recited in claim 5 wherein a device coupled to the product or item tag, the container tag, and the insulator or refrigerant unit tag by wireless transmission calculates the estimated time that the environmental specifications will be maintained within the container based on the thermal properties of the insulator or refrigerant unit and container and an estimated external environmental condition surrounding the container and updates the estimated time of validity stored in the memory of the product or item tag.

12. A system as recited in claim 11 wherein the device comprises a Bluetooth Low Energy (BLE) device.

13. A system as recited in claim 5 wherein a plurality of products or items having tags are in the container and the device collects minimum and maximum values of all environmental specifications from the product or item tags by wireless transmission within the container and combines those values into a set which forms a most restrictive environment and then validates that the most restrictive environment when combined with the insulator or refrigeration unit tag specifications collected by wireless transmission will maintain a proper environment during storage or shipment and issues a notification if the supplied insulation and/or refrigerant is insufficient.

14. A system as recited in claim 7, further comprising a second sensor affixed outside of the container to measure environmental conditions surrounding the container during storage or shipment, wherein the second sensor comprises a transmitter to communicate wirelessly to the sensor within the container the external measurements which impact the estimated time of validity, and the sensor within the container updates the product or item tag to store a new estimated time of validity.

15. A system as recited in claim 14 wherein the second sensor comprises a Bluetooth Low Energy (BLE) device.

16. A system as recited in claim 3 wherein a plurality of products or items having tags are in the container and a device collects minimum and maximum values of all environmental specifications from the product or item tags by wireless transmission within the container and calculates if the environmental specifications are compatible with one another and, if not, issues a notification that the products or items cannot be stored or shipped together.

17. A system as recited in claim 16 wherein the device comprises a Bluetooth Low Energy (BLE) device.

18. A system as recited in claim 3 wherein a plurality of products or items having tags are to be stored or shipped in the container and a device collects physical specifications from the product or item tags by wireless transmission and the physical specifications of the container tag collected by wireless transmission and calculates if the combined physical size of the products or items will fit within the physical dimensions of the container and, if not, issues a notification that the combined products or items cannot be stored or shipped within the container.
