1 . A process for conducting a purchase transaction comprising:

storing in a database, a first prioritize set of funding sources received from a purchaser;

storing in said database, a second prioritized set of funding sources received from a merchant;

receiving, from a point of sale terminal associated with said merchant, a message containing information that identifies said purchaser;

receiving, from said point of sale terminal associated with said merchant, a message containing a transaction amount for said purchase transaction;

selecting a funding source to affect said purchase transaction based on said first and said second prioritized list; and

conducting a transfer of funds from said funding source to affect said purchase transaction using a server in communication with a back end payment processing system;

wherein:

said first and second prioritized sets of funding sources are stored in said database prior to said step of receiving said message containing information that identifies said purchaser; and

said server retrieves said first and second prioritized sets of funding sources from said database to select said funding source for said purchase transaction.

2 . The process of claim 1 , wherein said transfer of funds comprises:

conducting a transfer of a balance of funds available from a first funding source in said first prioritized set of funding sources using said server; and

conducting a transfer of funds from a second funding source in said first prioritized set of funding sources using said server;

wherein said amount of funds transferred from said second funding source is equal to a total purchase price of said purchase transaction less said balance of funds available from said first funding source.

3 . The process of claim 1 , further comprising:

storing a third prioritize set of funding sources received from a purchaser in said database;

wherein either said first or said third prioritized set of funding sources is applied by said server to conduct said transfer of funds based on an identity of said merchant.

4 . The process of claim 1 , wherein

said server selects said funding source for said transfer of funds based on a purchase price of said purchase transaction.

5 . The process of claim 4 , wherein

said second prioritized set of funding sources includes a single prioritized funding source for each potential range of said purchase price.

6 . The process of claim 1 , wherein

said first prioritized set of funding sources is received from said purchaser via a communications channel that includes an SMS messaging system.

7 . The process of claim 6 , wherein

said message containing information that identifies said purchaser identifies said purchaser by a mobile phone number.

8 . The process of claim 7 , further comprising:

sending, to said point of sale terminal from said server, a request to confirm said purchase transaction;

receiving, at said server from said point of sale terminal, a response to said request to confirm said purchase; and

completing said purchase transaction if said response indicates that said purchaser has confirmed said purchase;

wherein said request to confirm said purchase transaction identifies said funding source for said transfer of funds.

9 . A computer-implemented method for performing a purchasing transaction between a purchaser and a merchant, the method comprising:

receiving, at a server device from a device associated with the merchant, a request to purchase an item or service from the merchant, the request comprising information about the item or service;

receiving, at the server device from the device associated with the merchant, information identifying the purchaser;

sending, to the device associated with the merchant from the server device, a funding source selection from a list of funding source options associated with the purchaser; and

completing the purchasing transaction, wherein the funds used to purchase the item or service are taken from the funding source selected;

wherein the step of sending the funding source selection comprises selecting a funding source based on (i) data associated with the purchaser or (ii) data associated with a history of purchases by the purchaser at the merchant; and

wherein the list of funding source options associated with the purchaser are configured a priori by said purchaser using a message sent to said server device via SMS.

10 . The method of claim 9 , wherein the step of completing the transaction comprises:

sending, to the device associated with the merchant from the server device, a request to confirm the purchase;

receiving, at the server device from the device associated with the merchant, a response to the request to confirm the purchase; and

completing the purchase transaction if the response indicates that the purchaser has confirmed the purchase.

11 . The method of claim 9 , wherein

the information identifying the purchaser comprises a mobile telephone number of the purchaser.

12 . The method of claim 9 , wherein:

said step of sending the funding source selection comprises selecting a funding source based on data associated with the purchase; and

said data associated with said purchase is a total purchase price of said purchase.

13 . The method of claim 9 , wherein

said step of sending the funding source selection comprises selecting a funding source based on a history of purchases by the purchaser at the merchant.

14 . A process comprising:

receiving a message sent via SMS from a purchaser, said message containing an a priori funding source selection for a payment service used to conduct a purchase transaction;

receiving, at a server device from a device associated with a merchant, a request to transfer funds to said merchant on behalf of said purchaser; and

completing said purchase transaction, wherein said funds transferred to said merchant on behalf of said purchaser are taken from a funding source selected by said a priori funding source selection;

wherein said a priori funding source selection is stored so as to apply to all future transactions conducted by said purchaser using said payment service until said payment service receives a second a priori funding source selection from said purchaser.

15 . The process of claim 14 , further comprising:

receiving, at said server device from said device associated with said merchant, information identifying said purchaser;

wherein said information identifying said purchaser comprises a mobile telephone number of said purchaser.

16 . The process of claim 14 , wherein

said a priori funding source selection includes a set of prioritized funding sources.

17 . The process of claim 16 , wherein

said step of completing said purchase transaction includes exhausting a first payment source in said set of prioritized funding sources and taking funds from a second payment source in said set of prioritized funding sources.

18 . The process of claim 14 , further comprising:

receiving, at a server device from said purchaser, a second message via SMS, said message containing a second a priori funding source selection for said payment service used to conduct said purchase transaction;

wherein said a priori funding source selection and said second a priori funding source selection are used by said server to formulate a set of prioritized funding sources.

19 . The process of claim 18 , wherein said step of completing said purchase transaction comprises:

comparing said set of prioritized funding sources to a second set of merchant preferred funding sources; and

conducting a transfer of funds from a most highly ranked agreed upon funding source in said set of prioritized funding sources;

wherein said most highly ranked agreed upon funding source:

appears in said set of prioritized funding sources; and

is ranked higher in said set of prioritized funding sources than any other funding source that appears in said second set of merchant preferred funding sources.

20 . The process of claim 18 , wherein:

said second a priori funding source selection consists of a same set of funding sources as said a priori funding source selection, but has a different prioritized order for said set of funding sources; and

said a priori funding source selection and said second a priori funding source selection are stored together in a database.
