Methods and apparatuses are provided using RFID devices to assist in determining an open status of a container. For example, a first RFID tag is fixed to a first portion of the container and a second RFID tag is fixed to a second portion of the container. Upon a user action to at least partially open the container, the first and second portions will move relative to each other, such that one or more of the RFID tags will no longer be readable by the RFID-tag reader or will now be readable by the reader. The reading or cessation of reading of one or more RFID tags indicates at least one open status of the container. In some embodiments, the open status is at least one of an unsealing confirmation, an open motion initiation status, an open motion confirmation, a partial open status and a fully open status. |
