RFID har sedan 80-talet vuxit fram inom industri- och transport-branschen som ett sätt att under-lätta spårning av tillgångar och övervakning av informationsflöden genom logistikkedjan. Tek-nologin har idag många olika applikationsområden och används inom en mängd olika verksam-heter. Item-level Tagging (ILT) är ett sätt att utnyttja tekniken genom att märka enskilda varor för att på så sätt ge dem unika identiteter, vilket erbjuder enorm potential inom detaljhandel. Givet potentialen med tekniken vill vi med vår studie undersöka vilka förutsättningar som kommer att krävas för en ökad användning av ILT och RFID inom detaljhandeln. Detta mål uppnås genom att undersöka de barriärer som tidigare har hindrat en ökad användning samt hur dessa barriärer uppfattas i dagsläget. Efter en grundlig litteraturgenomgång samt intervjuer med respondenter med skilda perspektiv inom området kunde vi dra slutsatsen att det i dagsläget är fyra förutsätt-ningar som behövs för att användningen skall öka; (1) Gemensamma standarder för hur RFID-data skall kodas, (2) Konkurrensmässig press, (3) En ökad kunskap om nyttoeffekter för specifika verksamheter, (4) En ökad kompetens gällande systemlösningar. / Since the eighties RFID has been used in industry and logistics as a way to ease tracking of assets and supervising information flows through the logistical chain. Today, the technology can be applied in a number of different ways and is used in a variety of businesses and branches. Item-level Tagging (ILT) is one way to apply the technology by tagging separate items and thus giving them unique identities, which offers enormous potential within retail. Given the technology’s potential our goal with this study is to discover which prerequisites are necessary for an increased use of ILT and RFID in retail. We achieve this goal by studying earlier barriers to adoption and how these barriers are perceived today. A thorough literary review and interviews with respond-ents from differing perspectives within the field enabled us to draw the conclusion that there are four prerequisites that are necessary today for an increased adoption; (1) Common standards for encoding RFID-data, (2) Competitive pressure, (3) Increased knowledge concerning beneficial effects of adoption, (4) Increased know-how concerning system solutions.

Although the origins of Radio Frequency Identification (RFID) technology can be traced back for many years, it is only recently that RFID has experienced rapid growth. That growth is mainly due to the increasing application of this technology in various supply chains. The widening of the implementation of RFID technology in supply chains has posed many challenges and one of the biggest is the degradation of the RFID system performance when tagging metallic objects, or when the RFID system operates in a metallic environment. This thesis focuses on tackling the issue of having metallic objects in an Ultra High Frequency (UHF) RFID system. The work presented in this thesis contributes to the research on UHF RFID systems involving metallic objects in several ways: (a) the development of novel RFID tags that range from a simple tag for general applications to tags suitable for metallic object identification; (b) the tag designs target the criteria of minimal tag size and cost to embrace the vision of item level tagging; and (c) the analysis of the performance (through theoretical predictions and practical measurements) of an RFID tag near metallic structures of various shapes and sizes. The early part of this thesis provides a brief introduction to RFID and reviews the background information related to metallic object identification for UHF RFID systems. The process of designing a basic tag, and additional information and work done related to the process, are outlined in the early part of this thesis. As part of this fundamental research process, and before proceeding to the designing of tags specifically for metallic objects, a small and low cost RFID tag for general applications was developed. Details of the design of this tag, with the application of this tag for animal identification, are presented. In the later parts of the work, different tag design approaches were explored and this has generated three rather different RFID tags suitable for attaching to metallic objects. The aim of this research is not just to design tags for metallic objects but also to tackle the constraints of having tags that are small in size, cost effective and suited in size to some familiar objects. Hence, in the later part of this research, the work took a step further where one of the three tags designed for metallic objects addressed the challenge of identifying individual small metallic beverage cans. RFID involves tagging of different types of objects and a tag may be required to be located in a depression of a metallic object. In the final part of this research, the read range performance of one of the RFID tags designed for metallic objects was analysed when the tag was located in metallic depressions of various shapes and sizes. The analysis was performed from a combination of theoretical calculation and simulation perspectives, and also through practical real-life measurements. Metallic objects are very common around us. Their presence is unavoidable and so to identify them, having the appropriate RFID tags suitable for operation on metallic surfaces is essential. Frequently the tags must be small in size and low in cost to allow identification at item level of individual small metallic objects. Understanding and being aware of the potential effects of metallic structures of various shapes and sizes on the tag performance is thus important. The research in this thesis into all the above can bring the industry further towards full deployment of RFID down to item level tagging. / Thesis (Ph.D.) - University of Adelaide, School of Electrical and Electronic Engineering, 2008

Titel: Implementering av RFID i tredjepartslogistik (TPL) - En fallstudie av RFID inom lagerverksamhet i TPL med fokus på implementering och kostnadskalkyler i in- och utleveransprocessen på PostNord TPL  Kurs: 4FE19E Examensarbete i Supply Chain Management för Civilekonomprogrammet, 30 hp.  Författare: Jacob Holm & Amer Basic Examinator: Helena Forslund Handledare: Hana Hulthén  Bakgrund: PostNord TPL i Ljungby är en av de aktörer som har fått upp ett intresse för RFID och det hela började med ett önskemål om RFID-tekniken från deras största kund (Kund X). Kund X efterfrågar en RFID-märkning på artikelnivå för att bland annat dra fördelar av en sådan teknik vid lagerinventering. För att PostNord TPL:s största kund ska kunna ta steget mot att implementera en RFID-lösning ute i butikerna, så krävs det att lagret i Ljungby implementerar tekniken först. PostNord TPL:s tanke, utefter kundens önskan att erbjuda dem denna tjänst, är att all RFID- märkning av Kund X artiklar sker på lagret i Ljungby. Denna studie är unik i sitt slag dels för att det förekommer ett stort forskningsgap i den existerande forskningsteorin med användning av RFID-teknik inom TPL, men att studien också fokuserar på RFID-märkning på artikelnivå.  Syfte: Syftet med studien är att föreslå riktlinjer för en implementering av RFID inom TPL i in- och utleveransprocessen. Riktlinjerna innehåller kategorisering av relevanta variabler för RFID-implementering samt implementeringsprocessen och kostnadskalkyl.  Metod: Denna studie är en fallstudie på företaget PostNord TPL i Ljungby. Forskarna har tillämpat en mönsterjämförelse där teorin och empirin har jämförts. Empirin har samlats in genom målstyrt urval och snöbollsurval, där semistrukturerade och ostrukturerade intervjuer med ett flertal olika aktörer har genomförts. Studien grundar sig i en kvalitativ forskningsmetod med ett deduktivt angreppssätt.  Slutsats: Studien har analyserat tre forskningsfrågor, där den första är mer generell inom TPL och de andra två riktar sig mot PostNord TPL förutsättningar. Studien har tagit fram förslag på vilka variabler som är relevanta vid implementering av RFID inom lagerverksamhet i TPL och hur de kan kategoriseras. Vidare har studien visat i vilken lagerhanteringsprocess RFID kan implementeras hos PostNord TPL och hur en sådan implementeringsprocess kan se ut. Slutligen har även tre olika kostnadskalkyler utvecklats för en RFID-implementering i in- och utleveransprocessen hos PostNord TPL. / Title: Implementation of RFID in third-party logistics (TPL) - A case study of RFID in warehousing operations in TPL with a focus on implementation and cost calculations in the inbound and outbound process at PostNord TPL  Course: 4FE19E Degree Project in Supply Chain Management for the Master of Business Administration Program, 30 hp. Authors: Jacob Holm & Amer Basic Examiner: Helena Forslund Tutor: Hana Hulthén  Background: PostNord TPL in Ljungby is one of the actors that has developed an interest in RFID, and it all started with a request for RFID technology from their largest customer (Customer X). Customer X requests an RFID tag at the item level, among other things, to take advantage of such technology during stock inventory. In order for PostNord TPL:s largest customer to be able to take the step towards implementing an RFID solution in the stores, it is required that the warehouse in Ljungby implements the technology first. PostNord TPL:s idea, according to the customer's desire to offer them this service, is that all RFID labeling of Customer X items takes place at the warehouse in Ljungby. This study is unique in its kind, partly because there is a large research gap in the existing research theory using RFID technology within TPL, but also because the study focuses on RFID labeling at article level.  Purpose: The purpose of the study is to propose guidelines for an implementation of RFID within TPL in the inbound and outbound process. The guidelines contain a categorization of relevant variables for RFID implementation as well as the implementation process and cost calculation.  Methodology: This study is a case study at the company PostNord TPL in Ljungby. The researchers have applied a pattern comparison where the theory and empiricism have been compared. The empirics have been collected through goal-directed selection and snowball selection, where semi-structured and unstructured interviews with a number of different actors have been conducted. The study is based on a qualitative research method with a deductive approach.  Conclusion: The study has analyzed three research questions, where the first is more general within TPL and the other two focus on PostNord TPL conditions. The study has produced suggestions on which variables are relevant when implementing RFID within warehousing operations in TPL and how they can be categorized. Furthermore, the study has developed in which inventory management process RFID can be implemented at PostNord TPL and what such an implementation process can look like. Finally, three different cost calculations have also been produced for an RFID implementation in the inbound and outbound process at PostNord TPL.
