=3D=3D=3D=3D
This section specifies the requirements of the shop register that will
be implemented on the Fisterra project.=20
Basically, the operation of the shop register is: a client arrives to
the shop, takes a set of articles, then goes to the shop register, where
a cashier, that has been identified by the system previously, passes
each article by a bar code reader, the application calculates the total
price, the cashier select the payment method and finally returns the
remaining money to the client.
The client can refund the articles in the next X days. The client must
go to Information counter, where he receives a refund ticket, then he
must go to the shop register where the cashier returns him the money.
The method of refund is the same that the client used when he bougth the
articles, so that if the client paid with credit card the refund is with
credit card.=20
The shop register contains 5 use cases:=20
* UC 1: Shop register =E2=86=92 Cashier
* UC 2: Refund of articles =E2=86=92 Staff of information
* UC 3: Retired of money =E2=86=92 cashier
* UC 4: Checking of shop register =E2=86=92 Cashier
* UC 5: Checking of shop =E2=86=92 Shop chief
Use case 1: Shop register =E2=86=92 Cashier
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
This use case allows the cashier to charge the articles that a client
want to purchases. The cashier passes the articles by the reader of the
bar code and it will be included in the ticket. If the client takes
several equal articles the cashier can pass only one by the reader of
bar code and to multiply by the number of units.

can create other ticket and then to recover the previous ticket.
The possible payment methods are:
1. In cash.

quantity by the client and the application calculates the quantity to
return.
When a client want to refunds one or various articles has to go to
Information, there he receive a refund ticket and then he has to go to
the shop register, where the cashier gives him the money. there are two
situations:
1. The refund ticket of the client has bar code: the cashier passes
the tickect by the reader of bar code, then the application show
this ticket with the articles refunded by the client, the
quantity of each one and the refund method. The cashier accepts
the operation and two tickects will be printed, one for the
client and another is stored associated with the refund ticket.

a number associated to this refund, so that the cashier will
introduce it and then the application shows the ticket just as
