Towards unified tag data translation for the Internet of Things

Following the ldquoInternet of thingsrdquo concept, each object will be associated with a unique identifier which will allow to retrieve information about it in large databases. In the process of retrieving information, this identifier (ID) may have to be translated into different formats (e.g. domain name style format for object name service query, binary, legacy,...). The tag data translation (TDT) is responsible for the translation of IDs into these different formats. We propose a general TDT system which extends the standards of EPCGlobal which only targets electronic product code (EPC). We integrate other RFID and smart cards standards (such as ISO 14443 and 15693) and GS1 standards which are more general as they also deal with bar code (EAN/UPC).
