Abstract: A method and system for making payments from a vehicle using onboard wireless communication systems. A Near Field Communication (NFC) reader is placed a vehicle, such that a customer can pass an NFC-enabled phone or credit card near the reader to provide a source of funding for a purchase. A Dedicated Short Range Communications (DSRC) radio onboard the vehicle communicates with a seller of products or services, such as a fast food restaurant, a parking garage, or a toll booth. The seller communicates to the vehicle the amount of a pending payment, the customer approves the payment within the vehicle, and the vehicle sends the authorization to the seller. The entire transaction is handled wirelessly, without the customer having to leave the vehicle or roll down a window. Pre-approval accounts can also be established for certain types of payments, thus making those payment transactions automatic.
