Solution Overview
Problem
Credit and debit card transactions face security and convenience issues due to reliance on physical cards, which can be compromised or inconvenient, especially with magnetic stripe wear and limited acceptance by vendors.
Innovation Solution
A method and system utilizing bi-directional RFID for secure wireless identity establishment, involving a pseudo-random username and password generator, and public key encryption to securely connect devices to wireless networks via a security server, enabling secure data transmission over SSL-encrypted channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If credit card or debit card is used for transactions, then payment capability is provided, but security is compromised when card is lost or card number is stolen
Solution Approach 1:
The patent replaces the physical credit/debit card with a digital copy in the form of a mobile device containing RFID technology. The mobile device contains the same payment information and authentication credentials as the physical card, allowing transactions to be performed digitally. This copying approach eliminates the security risks associated with physical card loss while maintaining payment functionality.
Solution Approach 2:
The patent substitutes the mechanical physical card system with an electronic RFID-based system. Instead of swiping a physical card through a magnetic stripe reader, the mobile device uses contactless RFID communication to transmit payment information wirelessly to the payment terminal, eliminating the need for physical card handling and improving security.
2Ease of operation
If physical credit or debit card is required for purchase, then transaction can be completed, but convenience is reduced when card is not physically available
Solution Approach 1:
The payment credentials are copied from the physical card to the mobile device, which is always carried by the user. This digital copy eliminates the need to search for or remember to bring the physical card, as the mobile device is already in the user's possession for communication purposes.
Solution Approach 2:
The mobile device serves multiple functions: it acts as both a communication device and a payment card. This multi-functionality means the user does not need to carry separate physical items for different purposes, and the same device can be used for both communication and payment transactions.
3Reliability
If magnetic stripe of card is used for data transfer, then payment information can be transmitted, but reliability decreases due to wear down over time
Solution Approach 1:
The patent replaces the mechanical magnetic stripe system with an electronic RFID system. The RFID system uses electromagnetic fields to transmit data wirelessly without physical contact, eliminating the wear and tear that occurs with repeated swiping of the magnetic stripe. This extends the functional lifespan of the payment credential system.
Data Source
AI summary
A method, a system, and a computer program product are provided for wireless establishment of identity via bi-directional radio-frequency identification (RFID). The method is implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions operable for sending device data including at least a username and a password to a transceiver. The method also includes receiving an identifier of an access point in a wireless network from the transceiver, the transceiver sending the device data to the access point via a security server. The device data is sent to the access point based on the identifier of the access point, the access point establishing a secure connection to the computer infrastructure based on the device data received from the transceiver and the computer infrastructure.
