Methods and devices for managing composite transactions

Abstract

Disclosed is a method for the management of composite transactions including a main transaction and at least one additional operation in an arrangement including a device (205) for initiating a transaction, a device (215) for proposing at least one additional operation depending on the characteristics of a main transaction and a device (220) for managing additional operations, the device for proposing at least one additional operation being accessible via a plurality of separate devices for initiating a transaction and via a plurality of separate devices for managing additional operations.

1 . A method for management of a composite transaction comprising a main transaction and at least one annex operation, this method being carried out in a set comprising a device ( 205 ) for initiating a transaction, a device ( 215 ) for proposing at least one annex operation according to characteristics of a main transaction and an annex operations management device ( 220 ), said device for proposing at least one annex operation being accessible by a plurality of separate devices for initiating a transaction and by a plurality of separate management devices of annex operations, the method comprising the following steps,
 receiving information relative to said main transaction, said information being received from said device for initiating a transaction by said device for proposing at least one annex operation;   estimating at least one parameter of said at least one annex operation, from at least one predetermined rule, according to at least one received item of information relative to said main transaction, said estimation step being performed at said device for proposing at least one annex operation;   in response to an indication of acceptance of said at least one annex operation received from said device for initiating a transaction, transmitting to said annex operations management device data comprising at least said at least one parameter of said at least one annex operation,   said main transaction being managed independently of said steps of receiving, estimating and transmitting.   
     
     
         2 . The method according to  claim 1  further comprising a step of selecting said at least one rule for estimating said at least one parameter of said at least one annex operation. 
     
     
         3 . The method according to  claim 2  further comprising a step of receiving an identifier of said device for initiating a transaction, said at least one rule for estimating said at least one parameter of said at least one annex operation being selected according to said identifier of said device for initiating a transaction. 
     
     
         4 . The method according to  claim 1  further comprising an initial configuration step of at least one rule for estimating at least one parameter of at least one annex operation. 
     
     
         5 . The method according to  claim 1  according to which said data transmitted to said annex operations management device in response to an indication of acceptance of said at least one annex operation further comprise said information relative to said main transaction. 
     
     
         6 . The method according to  claim 1  further comprising a step of transmitting a print command to said device for initiating a transaction, said print command aiming at printing a receipt comprising said at least one parameter of said at least one annex operation and said at least one received item of information. 
     
     
         7 . The method according to  claim 6  wherein said print command further aims at printing a reference to an identifier of a personal entity on said receipt. 
     
     
         8 . The method according to  claim 7  according to which said data comprising at least said at least one parameter of said at least one annex operation further comprise said reference. 
     
     
         9 . The method according to  claim 1  further comprising a step of storing of said at least one parameter of said at least one annex operation. 
     
     
         10 . The method according to  claim 9  further comprising a step of generating a transaction based on at least one previously stored parameter of at least one annex operation. 
     
     
         11 . The method according to  claim 9  further comprising a step of generating a summary of annex operations, said summary comprising at least one previously stored parameter of at least one annex operation. 
     
     
         12 . The method according to  claim 1  further comprising a step of encrypting at least one datum transmitted between said device for initiating a transaction and said device for proposing at least one annex operation or between said device for proposing at least one annex operation and said annex operations management device. 
     
     
         13 . The method according to  claim 1  according to which the communication protocol between said device for initiating a transaction and said device for proposing at least one annex operation or between said device for proposing at least one annex operation and said annex operations management device complies with a standard of IP type. 
     
     
         14 . A computer program comprising instructions adapted to carrying out each of the steps of the method according to  claim 1  when said program is executed on a computer. 
     
     
         15 . A system comprising means adapted to carrying out each of the steps of the method according to  claim 1 . 
     
     
         16 . The method according to  claim 2  further comprising an initial configuration step of at least one rule for estimating at least one parameter of at least one annex operation. 
     
     
         17 . The method according to  claim 3  further comprising an initial configuration step of at least one rule for estimating at least one parameter of at least one annex operation. 
     
     
         18 . The method according to  claim 2  according to which said data transmitted to said annex operations management device in response to an indication of acceptance of said at least one annex operation further comprise said information relative to said main transaction. 
     
     
         19 . The method according to  claim 3  according to which said data transmitted to said annex operations management device in response to an indication of acceptance of said at least one annex operation further comprise said information relative to said main transaction. 
     
     
         20 . The method according to  claim 4  according to which said data transmitted to said annex operations management device in response to an indication of acceptance of said at least one annex operation further comprise said information relative to said main transaction.
