Automatic payment system using RF ID tags
View Patent ↗The present invention discloses systems and methods for enabling cashless fueling transactions through the use of vehicle-based decal sticker RFID tags. The tags store a unique customer identification number as well as other frequent purchase information. When read by a reader installed at the fuel dispenser, the tag information is sent to the network host via the Point of Sale (“POS”) system, where it is linked to a customer's account for transaction processing and subsequent activation of the fuel dispenser. Several tags may be read by a single interface unit, avoiding the need to connect a tag reader to each fuel dispenser.
1. A method of validating a tag, comprising:
(a) resetting a stationary vehicle timer;
(b) automatically detecting a presence of a vehicle bearing the tag;
(c) outputting to a point of sale device a tag detection start message and identification information identifying the tag;
(d) performing a sale in accordance with the identification information, using the point of sale device, and using the tag as a medium of payment;
(e) receiving tag write data from the point of sale device; and
(f) writing the tag write data into the tag;
wherein step (b) comprises determining that the vehicle has been stationary for a period exceeding the stationary vehicle timer and based on the determination outputting to the point of sale device that the presence of the vehicle has been detected.
2. The method of claim 1 , wherein the sale comprises a sale of fuel for the vehicle.
3. The method of claim 2 , wherein: a plurality of fueling stations are provided, each with a vehicle presence detector and an antenna;
the vehicle presence detectors and the antennas are in communication with a single controller subsystem which is in communication with the point of sale device; and
detecting by one of the vehicle presence detectors the presence of the vehicle and based on the detection the controller subsystem activates a corresponding one of the antennas.
4. The method of claim 1 , further comprising receiving a manual input of a personal identification number, and wherein step (c) comprises performing the sale in accordance with both the identification information and the personal identification number.
5. The method of claim 1 , wherein the tag write data comprise data regarding the sale.
6. The method of claim 5 , wherein the tag stores frequent purchase information.
7. The method of claim 6 , further comprising:
(f) reading the frequent purchase information; and
