Abstract: This invention provides an embedded light sensor in the card that controls whether the card can transmit card data when energized by an RF energy source. Certain smart, debit or credit cards energize internal component within the card when entering into certain RF energy fields. The use of a light sensor detects whether a predetermined light level exists. If the predetermined light level is reached, the card's logic assumes that the transaction is authorized and allows for transmission of the card's data to a card reader. If the predetermined light level is not reached, the card's logic assumes that the card is still in a purse or wallet and that the RF energy field is not related to card transactions or the RF energy field belongs to fraudulent parties who seek to capture the card's data in an unauthorized manner.

Abstract: This invention provides a dynamically generated security code for smart, debit and credit cards as a way to thwart fraudulent use of these cards in financial transactions. The card internally contains a processor connected to a viewable display powered by a battery where the processor is capable of generating security codes on a periodic basis. The card can generate the security code by encrypting certain data is a way that the card issuer as the same security codes so that when the security code is used in a financial transaction, the card issuer can ascertain whether the transaction is valid and authorized or potentially fraudulent.

Abstract: This invention provides a smart badge having a processor connected to a viewable display where both the processor and the display are embedded in the smart badge. The embedded components may be powered by an embedded battery or by RF energy generated by a smart badge reader. The badge can be uploaded with a digital image of the badge holder and predetermined criteria uploaded into an embedded memory location in the smart badge. Such predetermined criteria may include the name and contact information of the badge holder as well as the buildings or secure areas the badge holder is authorized to access. The smart badge may also be capable of generating secure codes for the badge holder to use as pass codes for accessing computer networks. The smart badge may also contain embedded location sensors that when merged with maps stored in the smart badge's memory can assist the badge holder in determining location.

Abstract: A portable electronic device, for example an electronic card, includes at least one electronic unit associated to an optical switch which can be actuated by a user and which includes two photo-detectors arranged sufficiently far from each other in the electronic device to enable the user to cover only one of the two photo-detectors with one finger. The switch includes a logical circuit to which are provided a first and a second light reception signal respectively coming from the two photo-detectors. The logical circuit is arranged to supply a signal which only indicates actuation of the optical switch when the first and second light reception signals correspond to two different logical states for the logic circuit.

Abstract: An electronic tip calculator for providing an instant tip calculation to a user is disclosed. The electronic tip calculator comprises a touch keypad located on a front surface, a display screen located on the front surface and a power button located on the front surface. The touch keypad includes a plurality of touch buttons. The display screen is configured to display a tip amount and a total bill amount to the user and the power button is configured to activate the electronic tip calculator. The display screen allows the user to instantly retrieve the tip amount by navigating through the touch keypad. The touch keypad and the display screen are configured to provide a simple and convenient means of tip calculation to the user. The electronic tip calculator can be easily configured to calculate any tip rate as desired by the user.

Abstract: An electronic information card for retrieving information pertaining to a banking account of a user is disclosed. The electronic information card comprises a casing having a front surface and a rear surface, a payment chip and a memory chip located inside the casing, a touch keypad located on the front surface, a display screen located on the front surface and an activate button located on the front surface.
