Definitions and commonly used terms
Before going to the detail of the invention including some of the relevant prior arts, here are some definitions of commonly used terms.
NFC SIM – Near-field communication (NFC) is a set of communication protocols that enable two electronic devices, one of which is usually a portable device such as a smartphone, to establish communication by bringing them within 4 cm (11/2 in) of each other (https://en.wikipedia.org/wiki/Near-field_communication ). So basically NFC is a set of ideas and technologies that enable smartphones and other devices to establish radio communication with each other by touching them together or bringing them into proximity, typically a distance of 10 cm (3.9 in) or less. The NFC SIM card is just a combination of a normal SIM card and a NFC chip in one card.
GPS tracking unit - A GPS tracking unit is a navigation device normally carried by a moving vehicle or person that uses the Global Positioning System (GPS) to track the device's movements and determine its location. The recorded location data can either be stored within the tracking unit or transmitted to an Internet-connected device using the cellular (GPRS or SMS), radio, or satellite modem embedded in the unit. This allows the location to be displayed against a map backdrop either in real time or when analyzing the track later, using GPS tracking software. Data tracking software is available for smartphones with GPS capability (https://en.wikipedia.org/wiki/GPS_tracking_unit).
Thermoelectric Generator Film - A thermoelectric generator (TEG) is a solid state device that converts heat flux (temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect (a form of thermoelectric effect). (https://en.wikipedia.org/wiki/Thermoelectric_generator)

Rectenna (Rectifying Antenna) is also a self -charging component. A rectenna is a rectifying antenna — a special type of receiving antenna that is used for converting electromagnetic energy into direct current (DC) electricity. They are used in wireless power transmission systems that transmit power by radio waves.

Inductive charging - Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. The most common application is the Qi wireless charging standard for smartphones, smartwatches and tablets. Inductive charging is also used in vehicles, power tools, electric toothbrushes and medical devices. The portable equipment can be placed near a charging station or inductive pad without needing to be precisely aligned or make electrical contact with a dock or plug.

This publication presents a location based approach for user authentication in an online banking environment. The physical location of the user is identified using two different methods. Firstly, IP geo-location of the user's computer system is used. Secondly, User is assumed to have a mobile device, which is used to identify the current physical location of the user. Both locations are used to determine whether a mobile device or user is near to the computer system, which is being used for transaction. Based on this information, the legal user is authenticated implicitly.

OBJECTS OF THE PRESENT INVENTION
The primary object of the present invention is to locate the lost electronic card by GPS tracker which can remain operative for longer durations.
Another object is to disclose the electronic card with self-charging and inbuilt GPS tracker.
Yet another object of the present invention is to disclose the electronic card with wireless self-charging method.

DETAILED DESCRIPTION OF THE INVENTION
The present invention discloses a wirelessly self-charging electronic card with continuous location tracker.
Specifications of the card:
Cards are part of a payment system issued by financial institutions, such as a bank, to a customer that enables its owner (the cardholder) to access the funds in the customer's designated bank accounts, or through a credit account and make payments by electronic funds transfer and access automated teller machines (ATMs). Such cards are known by a variety of names including bank cards, ATM cards, MAC (money access cards), client cards, key cards or cash cards. The normal dimensions of the card is 86.7 x 53.9 x 0.76 mm.
In an embodiment of this present invention, the card looks like an ordinary bank card, but it can be tracked down with the help of a GPS chip (4), fitted inside the card (1) as well as an
Inductive Charging receiving coil/rectannea/Thermoelectric generator (TeG) film, attached at the backside of the card to recharge the Lithium Ion paper battery (2) wirelessly. The card (1) is infused with the NFC SIM (3) for secured transactions. These features are introduced in the card without disturbing its basic operations and abilities.
Lithium ion batteries (2) are used in a wide variety of portable equipment and instruments. Lithium polymer cells have a better form factor than cylindrical cells for a variety of applications, such as cell phones, PDAs, cameras. These cells are high-quality Chinese cells. Here the Dimension of the used battery is 80 x 21 x 0.5 mm. An ultra-thin Lithium Polymer Cell is placed which provides the power to the small GPS chip (4) that fits just above the battery.
GPS chip (4) is introduced near/above the battery which is providing the location of the card (1). This is fused with Timer IC and using suitable software, it may display the position on a map and it may offer directions. With Timer IC one can adjust the time of the data that is required after a particular time interval. Here the Dimension of the chip is 4.1 x 4.1 x 2.1 mm. At the back side of the card, there is a
Inductive charging receiving coil / Rectannea / Thermoelectric Generator which will charge the battery and enable it to perform further functions. Here are the dimensions 50 x 30 x 0.1 mm. The battery (2)
A Thermoelectric Generator is capable of generating electric energy from the heat flux that is
entertained by the TeG Film (5 of Figure 2). At the back side of the card the metallic strip is present. It is capable of storing data by modifying the magnetism of tiny iron-based magnetic particles on a band of magnetic material on the card.
The heart of the present invention is introducing the Wireless Self Charging method (5 of Figure 2), in the electronic card. If the card is lost or stolen, it would be difficult to track the card, even with the GPS tracker, when it will get out of power. So it is necessary to keep it charged for tracking purposes. But, eventually, as the card is very thin, so no charging points can be provided in the card body which can be plugged onto a charging point.
Here the inventors have carefully selected TeG film (5 of Figure 2) which is attached at the back side of the card (1) and recharges the card wirelessly and continuously, even from the minimum temperature differences. For example, if the card is kept on the palm top/table top or any other surface, the charging process will continue from the temperature difference of the surface and the outside weather, which will keep the card active constantly.
So failure of detecting the lost or stolen card due to GPS going out of power, can be taken care of and such card can be tracked always due to GPS getting power always just by the heat of the hand and temperature difference so created for the TeG to operate.
In another embodiment of the present invention, the means for self - charging of the card components is a RECTENNA.
In yet another embodiment of the present invention, the means for self - charging of the card components is based on Inductive charging and by this mean the card can easily be charged whenever the user passes by high EM source. This charges the batteries of the Card.
The battery (1) stores the charge collected by the Charging Utilities (2). Battery is a paper battery.
Means for charging of the battery (1) is Inductive charging Coil (2) which collects the charge as per the surroundings whenever the user passes by a high EM source. The GPS Module (3) is used to track the location of the Card. A separate network provider Module Called GSM (4) for GPS Module is also attached which is used to send/receive the location data. Control Board (5) is used to convert the binary codes into alphabets and numbers.

In yet another embodiment of the present invention, the means for self - charging of the card components are all three i.e Inductive charging, Rectenna and TEG which can be used as back-up in case of failure of one of these.

Novelty, Inventive Step and Industrial Application
NOVELTY
The present invention discloses a unique and easy method for recovery of the lost bank card or locking card without doing any transaction. This technique helps in searching the location of a lost card as well as identifying the location of the thief, if it is stolen. In this invention, the card consists of the NFC sim for secured transaction, one GPS chip, attached inside card for tracing the location, an ultrathin battery to provide power to the GPS chip and a means for self -charging of the battery fitted in card to recharge the battery wirelessly. Because of this self-charging feature, the card will never be discharged out to de- activate the GPS tracker. This unique idea has neither been disclosed nor anticipated by any of the prior art publications.

INVENTIVE STEP
The technical advancement of knowledge lies in disclosing the attachment of means for self-charging of the battery of the card.
