Founded in 2003, Powercast is the pioneer and leader of long-range, true wireless power-over-distance technology. The company's tiny Powerharvester receivers, embedded in devices, harvest RF energy sent over the air from either a dedicated transmitter or a typical UHF RFID reader. The embedded Powerharvester then converts the RF to DC to either directly power that batteryless device or recharge its batteries

  • Enables quick electronic price updates freeing retailers from changing paper labels and batteries

    Pittsburgh, PA – April 9, 2018 - Powercast Corporation, the pioneer of radio-frequency (RF)-based long-range power-over-distance wireless charging technology, announced that it will demonstrate the industry’s first Batteryless Electronic UHF (Ultrahigh Frequency) Retail Price Tag at RFID Journal LIVE! (Booth #1260) being held in Orlando, April 10 – 12. It is a finalist for the show’s Best New RFID Product 2018 Award, with winners announced April 12. The demonstration will feature Powercast’s RF-to-DC power harvesting technology which can wirelessly update an electronic paper (ePaper) display, sending data and power over the air up to two meters away using a standard UHF RFID reader. Powercast’s technology enables quick electronic price changes, operates perpetually without batteries, and works with typical UHF RFID readers (handheld and fixed). 

    Powercast developed the concept tag to free retailers from having to change paper labels as well as the batteries required by the industry’s battery-powered electronic price tags – both of which are labor-intensive jobs. An RFID reader can update a whole shelf of product prices within a few seconds. 

    How Powercast’s Batteryless Electronic UHF Retail Price Tag Concept Works

    Select the tag(s) to update and the new price in an app on a handheld UHF reader. (Retailers can easily integrate this function into their system.) Point the reader at the price tag, up to two meters away, to securely send pricing data and RF energy over the air to Powercast’s tiny PCC110 Powerharvester® wireless power receiver chip embedded in the tag. The chip converts RF to DC to power the tag without batteries, and updates the display with the new, authenticated price in a few seconds. The tags don’t need batteries because they can harvest enough power just from a UHF RFID reader to operate perpetually. 

    Other Enabling Technology in the Batteryless Price Tag:

    Powercast chose an ePaper display from E Ink because it can efficiently maintain the price image on the tag even when it’s outside of/not being directly powered by the UHF field. With both active matrix and segmented displays possible when designing electronic tags, the E Ink segmented display Powercast selected offers a more economical solution than the active matrix displays typically used in battery-powered electronic tags. Further, it doesn’t require a high-end display driver. 

    An evaluation kit for the Batteryless Electronic UHF Retail Price Tag is expected in Q4 2018 from distributors Arrow Electronics and Mouser Electronics.  The concept tag is available for license or Powercast will work with partners to design their own batteryless price tags using Powercast’s PCC110 chip.

  • The Tag harvests its power directly from a standard UHF RFID reader's RF signal using on-chip RF-to-DC power conversion.

    It enables quick price updates and frees retailers from changing paper labels or the batteries required by battery-powered electronic price tags.

    Powercast’s RF-to-DC power harvesting technology wirelessly updates the tag’s ePaper display, sending data and power over the air up to two meters away using a UHF RFID reader. It operates perpetually without batteries, and can update a whole wall or shelf of product prices in a few seconds.

The chip converts RF to DC to power the tag without batteries, and displays the new price in a few seconds. 

    The tag features E Ink’s digital ePaper display which maintains the price image without need for a constant power source.
