8. Houel – Workforce Manager
The manager is in charge of the
recruitment of all the employees
inside the firm. He determines you is
about to collaborate with them. If this
interview is a success, the employee
is going to join definitively the firm
and starts working.
When a new employee joins the firm, the manager
has to register him inside the database, in order to
configure a new bracelet for the employee. At the
end of this processus, the employee is register in
the database.
If there is a problem of any kind with the
configuration or the operation with the bracelet, the
manager can configure an other one using the same
processus than for the first time.

9. Houel – Warehouse Manager
Sometimes it is necessary to expand
the Warehouse of a firm for many
reasons. So it is necessary to see if it
is possible or no before to begin the .
If the expansion is possible, the manager can reach
the new location and check the NFC relative to the
location in order to register the location. If there is
some problem with this registration, the manager
can verified if everything was registered well and if
it is not done, realized the same operation. Here the
NFC is a crucial point to take in account during this
process of configuration.

10. Houel – Inbound Employee
When a product arrived, he is temporally dock, awaiting its identification. If the product was
not ordered by the manager, he will be rejected and reducing to the truck. If he was ordered,
he will passed by the quality check process. Finally if every points are validated, a
notification will be send in the aim of being stored. The location will be of course saved after
this process to accept the arrival and finish the process.

11. Houel – Sales Manager & Outbound Employee
When the sales manager received an message for the purchase manager concerning a new
order, the manager concerned will immediately verify if the product is available or not, to
perform and approved the order. The order will be rejected if the product is no more available in
the catalog.
The batch manager received after this a signal which inform him that the order is approved. His
role is to select the order to create the batch which corresponds.
When the batch is created, the outbound employees received a message which inform them. If
the order does not exists, an error signal will appear. But at the contrary, if the order exists,
they will collect all the information necessary to this process in the aim of scanning the product
and add it to the batch. They will also check the quantity to see if it is the right one or not and
then dock on the truck to finalize the order.

A Simple Write and read system for NFC devices

50. WriteT o Nf c
WriteToNfc was created to
highlight the main functions
allowed by the NFC tag. We
have created an app capable of
performing two operations:
- Write a Manager
- Read Device content

51. Write a Manager allows to insert
the Fiscal Code and Warehouse ID
in the label and then to write on
the tag NFC.
