Methods and apparatus for conducting financial transactions
First Claim
1. A method of conducting a financial transaction via radio frequency communications, the method comprising:
- transmitting, from a wireless master device, a first wireless command to initiate identification of one of a potential population of radio frequency communications devices, the wireless master device configured to transmit a plurality of subsequent wireless commands to continue the identification of the one radio frequency communications device, the first command including first bits that identify at least one radio frequency communications device;
receiving a reply at the wireless master device from the one radio frequency communications device, that has an identifier that includes the first bits;
determining whether there is a collision and if there is no collision in response to the first wireless command, identifying from the reply the identifier of the one radio frequency communications device; and
transmitting a second wireless command to individually identify the one radio frequency communications device using the identifier of the one radio frequency communications device that requests the one radio frequency communications device to transmit a subsequent reply; and
debiting an account associated with the one radio frequency communications device based at least in part on the replies from the one radio frequency communications device.

Abstract
A method of establishing wireless communications between an interrogator and individual ones of multiple wireless identification devices, the method comprising combining tree search and Aloha methods to establish communications between the interrogator and individual ones of the multiple wireless identification devices without collision. A system comprising an interrogator, and a plurality of wireless identification devices configured to communicate with the interrogator In a wireless fashion, the respective wireless identification devices having a unique identification number, the interrogator being configured to employ tree search and Aloha techniques to determine the unique identification numbers of the different wireless identification devices so as to be able to establish communications between the interrogator identification and individual devices without ones of the multiple wireless collision by multiple wireless identification devices attempting to respond to the interrogator at the same time.

8. A radio frequency communications-based method of conducting a financial transaction, comprising:
-
causing the transmission of a first wireless command requesting responses to start identification of at least one of a potential population of radio frequency communications devices configured to transmit at least identification information, the first wireless command specifying at least two bits to identify one or more first radio frequency communications devices and requesting the one or more first radio frequency communications devices to reply with respective identification numbers to be used by a master wireless device in subsequent communications to individually address the one or more first radio frequency communications devices; causing the master wireless device to determine whether there is a collision in response to the first wireless command; causing the identification of an identification number of a particular radio frequency communications device from a received response to the first command, if there is no collision in response to the first wireless command; causing the master wireless device to individually address the particular radio frequency communications device using the identification number identified from the received response to the first command; and receiving funds for the remote payment of goods or services based at least on part on the received response from the particular radio frequency communications device. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method of conducting a financial transaction via a radio frequency communications method, comprising:
-
causing the transmission of, from a wireless master device, a first wireless command to initiate identification of at least one of a population of radio frequency communications devices, the wireless master device configured to transmit a plurality of subsequent wireless commands to continue the identification of the at least one radio frequency communications device, the first command including first bits that identify radio frequency communications devices; causing the receipt of one or more replies at the wireless master device from respective ones of one or more radio frequency communications devices that have identifiers that include the first bits; causing the wireless master device to determine whether there is a collision, and if there is no collision in response to the first wireless command, causing the wireless master device to identify from the one or more replies an identifier of a first radio frequency communications device; and causing the transmission of a second wireless command to individually identify the first radio frequency communications device using the identifier of the first radio frequency communications device, the second command requesting the first radio frequency communications device to transmit a subsequent reply; and causing the debiting of an account associated with the first radio frequency communications device based at least in part on the replies from the first radio frequency communications device. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A method of conducting a financial transaction via a radio frequency communications device, comprising:
-
transmitting, from a wireless master device, a first wireless command to initiate communication with a population of radio frequency communications devices, the wireless master device configured to transmit a plurality of subsequent wireless commands to continue the identification of one or more of the population of radio frequency communications devices, the first command including first bits that useful in the identification of radio frequency communications devices; receiving one or more replies at the wireless master device from one or more radio frequency communications devices that each have a respective identifier that includes the first bits; determining whether a collision occurred as part of responding to the first command, and if no collision occurred, identifying from the one or more replies an identifier of a first radio frequency communications device; and transmitting a second wireless command to individually identify the first radio frequency communications device using the identifier of the first radio frequency communications device that requests the first radio frequency communications device to transmit a subsequent reply; and identifying a financial account associated with the first radio frequency communications device based at least in part on the identifier of the first radio frequency communications device; and debiting the account as part of the financial transaction. - View Dependent Claims (23, 24)
