Abstract

An invention for that incorporates RFID technology and a chip (2) with photovoltaic cells (1). To eliminate in some cases the need for batteries in active RFID tags or transponders. An invention that also uses rechargeable batteries (6) and also incorporates them connecting the batteries (6) to the photovoltaic cell (4) to recharge battery (6). This invention also covers all aspects related to combining or merging these two technologies RFID (Radio Frequency Identification) and Photovoltaics.

Claims

1. This invention is meant to reduce the cost of an active battery operated RFID chip with the use of photovoltaics.

2. This invention thou is not meant to completely eliminate the battery.

6. This invention does show in a rough way wiring schematics. Like the above claim number 2 the final wiring schematic will be up to the manufacturer. This patent should be inclusive of any or all possible wiring schematics.

3. This invention is meant to increase the life of the rechargeable batteries described above and increase read ranges for the RFID chips.

4. This invention does not eliminate in FIG. 1 the batteries necessity entirely but yet there are circumstances that require that the battery remain a function of this invention.

5. This invention does not show in FIGS. 1 and 2 what possible encasement or enclosures might look like. This patent should be inclusive of any enclosure for the invention. Enclosures are at the manufacturers discretion after licensing or the patents outright purchase.
