Abstract: An improved system, method and computer-readable instructions for tracking and monitoring vaccine and pharmaceutical information including data storage and environment sensing is provided. The improved method includes the steps of reading a tag associated with the vaccine, where the tag includes first information about the product and second information about the product recorded by an environmental sensor. The improved method further includes the step of determining the safety and efficacy of the product based on the readings from the tag, by comparing the first information including an expiration date with a current date to determine whether the vaccine has expired and by comparing the second information including a range of environments to a predetermined acceptable threshold range of environments indicating whether the product has exceeded the threshold.
