**5. Conclusions**

The implementation of a production chain traceability system by RFId tags and their readers (printers for initializing cards with RFId tags; tunnels to read warehouse entries and exits; printers for labelling boxes when dispatching) implied an investment of about 70,000.00 euros, increased by costs for the adaptation of the informatics management system and by current expenditure concerning periodical RFId tag purchase.

Many benefits were obtained: from production chain management with traceability of garments being repaired, to automatic management of the general warehouse and of consignment accounts with some customers, to management of commercial or defectiveness returns by customers and final consumers who purchase through Oscalito's e-commerce portal, on top of annulment of mistakes in the dispatching phase, eliminating claims on contents of the dispatched pieces, which used to concern about 100 pieces a year.

Finally, the implementation of the production chain traceability system by RFId tags has enabled to obtain important supply chain certifications, especially the Italian Identity certification issued by Italcheck.

Even if, according to Refs. [59, 60], common criticisms of the case study method are that it lacks rigour and that the dependence on a single case exploration makes it difficult to reach a generalising conclusion, the authors believe that through the Oscalito case study, they have been able to describe their views on a relevant innovative reality.

We realise that this research has some limitations due to the applied methodology: we have adopted a qualitative method for a single case study; the findings of the study are based on the first results of prospected deeper research; and further interviews would be required in order to understand a general fashion industry perception of this kind of technology.

For this reason, we are planning to carry out further studies on the application of RFId in the fashion industry.
