Discussions should take place with the RFID tag supplier, and supplier of printer encoders and RFID readers to define the specific features of the products already installed, compared with the RFID tag requirement defined in Clause 8 and the support for commands defined in Annex A.
The changeover process can be managed in a number of ways from a gradual changeover, possibly as items are returned, to a more accelerated programme. These need to be interoperable with any that are already installed.
Users of British Standards should make sure that they possess the latest amendments or editions.
The main task of technical committees is to prepare International Standards. A maximum length of characters should apply to all data elements that have a variable length display format. There are no features in this part of ISO that should impede particular business operations.
RFID systems that operate at frequencies other than 13,56 MHz have significantly different operational features from those operating at 13,56 MHz.
The processes described in this annex are presented in a manner to help the reader understand how input data is converted to encoded bytes on the RFID tag. The primary item identifier shall be encoded as the first data element on the RFID tag to allow for faster transactions across the air interface by invoking a read first object s argument in the read command see B.
If a single AFI is used, then a library may wish to lock this. The exceptions are explicitly discussed later in this subclause. Short Circuits in Power Systems: In this case, the AFI shall not be locked. A standard data model for encoding information on RFID tags could increase the cost-effectiveness of the technology within libraries particularly through greater interoperability of RFID tags and equipment, and enhance support for resource sharing between libraries.
The focus of this research project was to develop a data model for lifecycle information of a facility that would suit the requirements of the process industries. Although locking the primary item identifier is optional, under normal circumstances this data element should be locked to prevent various forms of digital vandalism.
Details of the software products used to create this PDF file can be found in the General Info relative to the file; the PDF-creation parameters were optimized for printing. In Part 7 the concept of Templates is introduced. It is supported by a Read-Type argument that enables only first objects such as the primary item identifier and OID-index to be read, or to read one or more objects, or to read all objects. Each participating computer system maps its data from its internal format to such ISO-standard Node and Template instances.
ISO/IEC 15962 – RFID Data Protocol
This avoids the risk of an RFID reader in another domain reading the Is tag on a loan item and confusing the encoded content with data for its own application.
NOTE If the data set did not end on a block boundary, then an offset and necessary pad bytes would need to be encoded, so that the next data set can be properly locked. Functional Safety [IEC stds]. The RFID tag shall support this command if the Read single block command is not supported 24 Optional Write multiple blocks The interrogator shall support this command.
Each alphabetic and punctuation character is encoded in 5 bits, and each numeric character in 4 bits. This avoids one component being permanently encoded and others changeable.
It is only capable of directly encoding Relative-OID values from 1, which encodes asto 14 which encodes as The RFID tag shall support this 15692 if the Read multiple blocks command is not supported 19562 Optional Write single block The interrogator shall support this command. The response indicates whether the operation was successful, or provides details of errors. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
If other security mechanisms are used, then the AFI may be locked at the individual library’s discretion. As such, it is the primary stage of the communication chain and is part of the response of the Inventory command.
Other applications may also make use of the ISIL. ISO standards by standard number.
The lock object argument in an application command effectively calls for the entire data set to be locked. For dated references, only the edition cited applies. NOTE Even though a pad byte is required, the length of the compacted data remains unchanged.
RFID reader using the ISO/IEC protocol
As this data set is not locked, and nor is the next data set, there is no need for block alignment. The hyphen minus character is essential to distinguish the boundary point between the various types of prefix and the library identifier. The following advice is intended to assist with encoding efficiency. It also enables a library system to reject items that carry a different AFI code, possibly from another domain visited by a client.
Take account of any requirements to exclude data on the legacy tag that is no longer required and to include new data elements not previously encoded. The option then exists to maintain both systems in parallel, at least for RFID tags with locked data until the number of legacy tags is relatively small to cost-justify a replacement RFID tag.
From this, it should be clear that there can be encoding efficiencies and a reduction in the number of bytes to be encoded if data sets that are to be locked are grouped together.
The relevant commands are described in Annex B. As such it is an internal code defined locally. Such technological developments are possible, and some are taking place for particular frequencies and particular air interface protocols. It also allows an individual library to vary the choices of data elements without the need for any major update.
Each object is provided as a byte stream supported by a Compact-Parameter. Other libraries in different parts of the world have installations based on various proprietary systems offered by technology and library system suppliers.
