Integrated contactless MPOS implementation

This invention describes a way for a mobile device to securely handle point-of-sale transactions. It works by having the mobile device receive a unique "seed" number from a network, which it then uses to create secret keys for encrypted communication and generate unpredictable numbers. This process enhances security by allowing the seed source to detect if incorrect keys or numbers are being used. The claims narrow this to a mobile device with both a terminal and a reader, where the reader specifically generates these keys using the received seed.

Why it matters: Filed before the widespread integration of secure elements and NFC readers into standard smartphones, the hardware platform for this method is now ubiquitous. This makes the software logic for secure key generation and communication more accessible for deployment in modern mobile payment systems.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSoftware logic, cryptographic implementation, secure hardware integration.
