Abstract

Claims (44)

1. An expedited method of assembling software systems, comprising the following steps:

a) fabricating a collection of software systems, each of which system contains

i) a processing module (PROC_MOD) which processes content of messages;

ii) a single packaging module (PAK_MOD) which packages said messages into packets for transport out of the system;

iii) a communication module (COM_MOD) which accepts and delivers message packets; and

iv) a system control module (CONTROL) which coordinates the processes of (i), (ii), and (iii);

b) during the fabrication of paragraph (a),

i) fabricating identical CONTROL modules in all of the software systems;

ii) fabricating identical COM_MOD modules in all of the software systems; and

iii) fabricating PAK_MOD modules in all of the software systems, such that:

A) a copy of a software unit A is contained in every PAK_MOD module;

B) some PAK_MOD modules contain a software unit B with no unit C; and

C) some PAK_MOD modules contain a software unit C with no unit B; and

c) installing the software systems into respective electronic payment switches.

2. Method according to claim 1 , wherein step b) includes:

iv) fabricating PROC_MOD modules in all of the software systems, such that each system contains a single PROC_MOD module, and:

A) a copy of a software unit D is contained in every PROC_MOD module;

B) some PROC_MOD modules contain a software unit E with no unit F; and

C) some PROC_MOD modules contain a software unit F with no unit E.

3. Method according to claim 1 , further comprising:

d) repeating steps of paragraphs (a) and (b) to thereby modify one or more of the software systems previously fabricated.

4. Method according to claim 1 , wherein the software unit A is combinable with a different processing module than said processing module PROC_MOD.

5. Method according to claim 1 , wherein

i) the software unit A has existence independent of said processing module PROC_MOD,

and

ii) the software unit A is selectively combinable with another processing module, different from processing module PROC_MOD.

6. Method according to claim 1 , wherein software units A, B, and C are not required to package messages into packets for said transport.

7. Method according to claim 1 , wherein the message processed by the PROC_MOD module comprises data representing bank checks which are processed in a paperless automated check exchange and settlement system.

8. Method according to claim 1 , wherein the message processed by the PROC_MOD module comprises

i) data representing bank checks; and

ii) a digital signature which allows authentication of the message.

9. Method according to claim 8 , wherein

i) the data includes a number for each check which identifies a bank, and

ii) one or more of the modules ascertains whether the numbers are correct.

10. Method according to claim 1 , wherein the message processed by the PROC_MOD module contains

(1) data which describes a group of bank checks,

(2) data which indicates a group total for the amounts of the checks, and

(3) a digital signature,

wherein one or more modules perform the following steps:

c) determine whether the drawee-bank listed in each check is correct;

d) tally the amounts of all checks into a tallied total;

e) determine whether the tallied total matches the group total;

f) verify validity of the message, using the digital signature; and

g) if steps (c), (d), (e), or (f) indicate an error, notifying a bank associated with a check producing the error.
