Radio Frequency Powered Smart, Debit, and Credit Card System Employing A Light Sensor To Enable Authorized Transactions

摘要

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. As a fail-safe, the card's logic may send a signal to the card holder when transactions are attempted in low light conditions that require the card holder to touch a button on the card or input a code for the transaction to proceed.
