A sensor device for conducting electronic transactions from a vehicle including a housing including an RFID circuit operably connected to an RFID antenna, a short range communication device, the RFID circuit and short range communication device operably connected to a processor, and a power supply. The sensor device is wirelessly connectable to a mobile communication device via the Bluetooth chip and the mobile communication device runs a software application. The RFID antenna is adapted to receive a wireless signal from a transmitter. Responsive to the wireless signal, the processor causes the short range communication device to wirelessly communicate with the mobile communication device to initiate a transaction.

This invention is in the field of private cryptographic transactions and discloses a method to create completely private escrow and swap transactions using a private or zero knowledge proving system.

A system and method are described for n alternate mobile payment service. The system includes a server computer for enrolling and storing user account information. The server computer is also capable of generating a unique one-time-use identifier for use during a transaction. The one-time-use identifier is returned to user as an electronic coupon which may be in the form of a two-dimensional barcode. The coupon may be used at a merchant location to complete a transaction. When the barcode is scanned it may processed similar to a credit/debit/prepaid card payment.

Techniques for invocating a smart contract are described. One example method includes receiving a target transaction that is used to initiate an invocation of a smart contract, wherein the target transaction comprises invocation data, and wherein the invocation data comprises a data digest associated with target data stored in a third-party storage system interconnected with a blockchain; querying the target data from the third-party storage system; receiving a query result returned by the third-party storage system, wherein the query result comprises encrypted target data; obtaining a key to decrypt the encrypted target data to generate decrypted target data; performing a content verification on the decrypted target data; determining that the content verification succeeds; invoking the smart contract to perform a smart contract computation on the invocation data; and storing a computation result in a distributed database associated with the blockchain after the smart contract computation is completed.

Systems and methods for multi-merchant tokenization may include receiving a transaction from a point of sale terminal of a merchant, validating the merchant ID against merchant logs, and generating a token for the transaction. The token includes a primary account number, expiration, and a group ID. Additionally, the system provides the primary account number to a payment system and receives a response back. The response is then output back to the merchant along with the token. In subsequent transactions, the system may receive the token from a one point of sale terminal of the merchant. The system validates the merchant ID against merchant logs and ensures the merchant is configured for tokenization. The token is decrypted and the group ID is compared to the merchant ID in the merchant logs. When they match, the primary account number is provided to the payment system for approval.

Systems and methods for using analyzed social media data to predict a forward resource market and automatically execute a resource transaction accordingly. An example system may include a machine having a resource requirement and a controller. The controller may include: a resource requirement circuit to determine an amount of a resource needed; a social media data circuit to interpret data from social media data sources; a forward resource market circuit to access a forward resource market; and a market forecasting circuit to predict a forward market price of the resource in response to the interpreted social media data. A resource distribution circuit may execute a resource transaction on the forward resource market in response to the determined amount of the resource and the predicted forward market price.
