For protecting confidential information in a printed document, the invention provides a system and method for, on one hand, encrypting the confidential content of the document and then printing the part or parts of the document with confidential information in an encrypted form and the rest of the document in a non-encrypted form, and, on the other hand, decrypting the encrypted document content for display and use or for printing. In addition, for preventing unauthorized copying and tampering of a printed document, the invention provides a system and method for managing a unique tag, which is attached to the document and which authenticates the document.

In some examples, a movement range indicating a geospatial boundary for executing delivery of a package may be received by a delivery tag. The geospatial boundary may be stored by the delivery tag. A position of the delivery tag with respect to the geospatial boundary can be determined using a location sensor of the delivery tag. It may be detected that the delivery tag has moved outside the geospatial boundary, in response to which an alarm may be generated.

An apparatus includes a printed antenna, a printed battery, a transmitter powered by the printed battery, and control circuitry configured to control the transmitter to transmit, using the printed antenna, information detected by a sensor.

The present invention is a tracking device for use in an LPWAN network, a system for using the tracking device, and a method of using the tracking device. The invention has the advantages of having a small form factor, low power consumption requirements, and long data transmission capabilities. In an embodiment, we describe a tracking device wherein the majority of the electronics are printed on a single substrate. In one variant of this embodiment, only a sensor could be located off-substrate. Embodiments disclosed herein provide a low-cost, versatile tracking device that can provide accurate analytics about a movable article to individuals or machines seeking information related to at least one of a panoply of metrics that could be reported about the moveable article.
