Example

The USC card can be used as a safe and reliable e-commerce card. Considering the aesthetics, it is possible to personalize it with the company logo and, thanks to the chip embedded in it, we can find the company's data:

title;

the addresses of the various establishments;

telephone number;

fax number;

e-mail;

URL;

VAT number;

A description of the services provided by the company.

These data can be used immediately by the receiving device when the card is near, without having to import the receiving device through the keyboard.

When the card is brought close to the mobile phone with bluetooth technology, the phone number of the company will be displayed on the display screen of the mobile phone, and the call will be sent immediately; moreover, we can store the phone number in the index book of the mobile phone immediately.

On the contrary, when the card is close to a computer with bluetooth technology, the system will display the data contained in the card and the private data that needs to be read and saved in different folders (invoicing program (invoicing program), outlook mail, company provided private data such as listings or services).

The card can also be used to insert a destination into a GPS device equipped with Bluetooth technology, eliminating the need to manually enter the address, inserting possible sites such as hotels, restaurants or organizing scheduled trips.

A feature is that when used to describe the services provided by the company, it can be stored in several languages and presented according to the needs of users.

The card can also be used in the financial banking sector, public surveillance, in the transport sector and by businesses as a replacement for existing cards or smart cards.

Technical Description

Therefore, the main purpose of the card is to communicate with different kinds of devices, such as mobile phones, PDAs, computers, laptops, or other electronic devices.

Depending on the amount of data to be sent/received, the device uses different technologies (wireless or bluetooth).

When the amount of data to be sent/received is low (like in cell phones and PDAs), the technology used is Bluetooth (or a similar new communication standard or higher), and when sending/receiving larger amounts of data (like when exchanging files between computers), the standard micro Wi-Fi shown (Wireless Fidelity—IEEE802.11b or similar new communication standards or higher standards, such as 802.11a/b/i/g).

Of course, it can implement different product types at different prices, and the products will vary according to the type of connected device and the amount of data sent.

general structure

bluetooth card

The card includes a bluetooth module managed by a central processor connected to the memory.

The Bluetooth module allows cable-free communication between the card and other devices.

Customer data is stored in memory.

In an optimal solution, a single microprocessing element (7) is used to integrate the processor (2) and memory (6). Power supply via battery (4) after pressing receive or send key (b) during data transmission.

For some specific applications, such as prepaid cards or credit/credit cards, an LCD liquid crystal device (8) can be added on the card to display data such as remaining credit limit.

WIFI card

When using the Wi-Fi standard instead of the Bluetooth standard, more data can be transmitted, so the card can be used to support larger file communications such as audio, video, etc., especially with the computer through the WLAN wireless network (local wireless network area) ). Since each user has different requirements for the memory according to the stored files, you can choose to increase the memory card (SD card, compact flash) at this time.

The biggest physical change is the use of a Wi-Fi module instead of a Bluetooth module.

The IEEE wireless standard 802.11b required components and recommended memory are described in Table 02, along with prices and dimensions.

For some specific applications, such as prepaid cards or credit/credit cards, an LCD liquid crystal device (8) can be added on the card to display data such as remaining credit limit.

The cost and size of the components are similar to the previous one, except for the high-capacity memory which is added according to the user's needs.

The processor and the battery can be replaced with similar components of higher speed and capacity, respectively.

Bluetooth/WiFi card

In order to cater for all possible wireless devices, a combo card is described that uses Bluetooth and Wi-Fi modules together.

Its general structure is illustrated in FIG. 6 . Obviously, the cost and power consumption are equal to all the components described earlier.

Description of the working system

The block diagram in Figure 7 describes the operation of the card. The "start" occurs when an energy source is connected to the circuit.

At this point, the card is powered off, so it consumes no power.

Activation can be performed via the "program key" or "send key".

When the "program key" is activated, the card enters the program mode, which means that the received data is stored in the memory.

When receiving and storing is complete, the card will stop and go to "off" automatically.

Conversely, when the "send key" is pressed, the data stored in the memory starts to be sent.

After the transmission is over, the card goes "off" to save energy and returns to the initial state.

Personal Enhancement Program

Turning now to the enhanced solution in Figure 1A, it is important to note that the highest enhanced solution refers to the same generic electronic card, or generic smart card, but with a personalization module (80). The card is of preferred form 80 x 55 x 3 mm, made of metal or plastic material, which contains the following elements:

(10) Wi-Fi module: it realizes wireless connection through standard IEEE802.11b;

(20) Bluetooth module: it realizes wireless connection through Bluetooth standard;

(30) USB pin connector: it connects the device to the USB gate, allowing battery discharge and data exchange;

(40) Rechargeable battery: its condition is monitored and displayed to the user while charging;

(50) Internal memory: it records the settings of the user;

(60) Microprocessor: it is responsible for managing peripherals;

(70) Flash card memory connector: it allows the use of external storage, adjusting the capacity (to 2GB) as needed;

(80) Fingerprint module: it detects the user's fingerprint, checks its authenticity, and is also a menu navigator;

(90) LCD display: it allows to see the menu and operation during the process.

Apparently, the card has an integrated antenna.

Obviously together with the elements (80, 90), there is also a series of keys with control functions, and/or input functions in the user interface.

The novelty and originality lies in the combination of all said elements, especially the addition of a fingerprint reader (80) for checking, identifying and allowing access to all functions.

In the picture, you can see that the new card looks very much like a normal credit card. The reduced size of the internal components allows the production of a plastic card, which can be custom printed with logos, images or others for aesthetics.

The card has a supporting base integrated circuit plastic material with said elements such as microprocessor or CPU, memory, transmission module, battery, LCD screen and on/off button.

Like the previous one, the card can receive, store and transmit much data and information only by being close to electronic devices equipped with Bluetooth technology and Wi-Fi or higher or similar communication standards, so, similarly, it can be used with commercial communication with different devices such as computers, laptops, PDAs, mobile phones or cell phones, satellite devices, and other electronic devices.

Similarly, using wireless communication without the need for cables or a USB connection, the card can be used in a variety of applications, but with a USB connection it is equally capable of any USB-like function.

The operation of the personal fingerprint reader card is illustrated in the block diagram of Figure 1A.

"Starting" occurs when an energy source is connected to the circuit.

At this point, the card is powered off, so it consumes no power.

Activation can be performed via the "program key" or "send key".

When the "program key" is activated, the card enters the program mode, which means that the received data is stored in the memory.

The card stops when receiving and storing is complete.

Conversely, when the "send key" is pressed, the data stored in the memory starts to be sent.

After the transmission is over, the card goes "off" to save energy and returns to its initial state.
