Problems solved by technology

[0005] However, smart tags do have certain disadvantages
For example, smart marks are more susceptible to physical damage than optical barcodes
Smart tags are also somewhat more expensive to use than optical barcodes
While optical barcode markings can be printed using traditional marking printers or even standard consumer grade inkjet printers, smart markings must be printed using a more specialized printer a

Abstract

A small differential-electric-field-activated UHF RFID device. Such a device may be small and easy to manufacture, improving the viability of incorporating RFID technology into articles like tickets,cards, and tokens. Such a device may also be small and inexpensive enough to allow for redundant RFID chips to be placed on an article, improving the survivability of an RFID-enabled article. Such a device may also reduce the amount of metal or plastic that is used in order to create an article such as a smart ticket or card, improving recyclability.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to and benefit of U.S. Provisional Patent Application No. 62 / 444,823, filed January 11, 2017, the entire contents of which are incorporated herein by reference. Background technique [0003] A "smart label", also called a "smart label", is a printed coded label that contains an extremely flat configured transponder as an inlay inside the label. These transponders typically include a chip, antenna and bonding wire. [0004] In many processes, such as in logistics and transportation, "smart tags" or "smart labels" have replaced more traditional optical barcodes, as well as 2D barcodes, QR codes, etc., as the key means by which items can be identified and tracked. Automation of such optical encodings is limited in the appropriate distance for read success, and often requires manual manipulation to bring the code into the scanner's field of vision (or, alternatively, requires the use of a sc...
