A card reader device is provided with a housing having a slot for swiping a magnetic stripe of a card to complete a financial transaction between a buyer and seller. A read head is in the housing reads data stored on the magnetic stripe and produces a signal indicative of data stored on the magnetic stripe. An output jack is adapted to be inserted into a microphone input associated with a mobile device for provides the signal indicative of data stored on the magnetic stripe to the mobile device. A sourcing power device couples to an audio jack of the mobile device and sources power from the mobile device through the audio jack.

Systems and methods for financial transaction through miniaturized card with ASIC

A method of establishing secure communication between a first mobile computing device and a second mobile computing device includes generating a first self-signed key at the first mobile computing device, pairing the first device with a second device, the pairing including receiving user input of a passcode and after receiving the user input sending the first public key to the second mobile computing device and receiving a second public key from the second mobile computing device, storing the second public key in a database of trusted devices, the database of trusted devices being stored in the first mobile computing device, receiving in the first mobile computing device a list of mobile computing devices connected to a mobile network, matching the list of mobile computing device against the database of trusted devices, and establishing secure communication between the first mobile computing device and the second mobile computing device.

Secure communications between devices

A new approach is proposed that contemplates systems and methods to enable an individual to complete a financial transaction by swiping a magnetic stripe card through a card reader connected to a mobile device. The size of the card reader is miniaturized to be portable for connection with the mobile device. The card reader is configured to reliably read data encoded in a magnetic strip of the card with minimum error in a single swipe and provide a signal that corresponds to the data read to the mobile device, which then decodes the incoming signal from the card reader and acts as a point-of-sale device to complete the financial transaction. Such an approach enables a person to become either a micro-merchant (payee) or a buyer/customer (payer) without having to purchase expensive card reader devices or software.
