Title: Supporting IATA RP1740
1Supporting IATA RP1740 RP1745 Through SC31
RFID Standards
2OPEN SYSTEM APPLICATION STANDARDSLegacy
Considerations
- Globally billions invested in AIDC related data
elements that form building blocks of databases - Migration to a new data carrier can take 3 to 7
years - Integration between RFID and bar code is highly
likely, so cannot depend exclusively on the new
technology - Integration Issues
- The proportion of the item range with RF tags
- The migration period
- Integration restricts RFID options
- For RFID there is no fundamental requirement to
encode data the same way, but data output can
emulate bar code
3OPEN SYSTEM APPLICATION STANDARDS The Issue of
Legacy Data Formats
- There are many different code structures in use
for logistics that vary by sector, function, or
country. EAN.UCC is one of many supported by bar
code. - Auto industry ? blood transfusion ? electronics
? military - ? paper ? pharmaceutical ? postal an so on
- Pharmaceutical codes in Germany ? Italy ? UK ?
USA - Many logistic systems have established
infrastructure of data formats - Many depend on some form of item attendant data
because of network problems, industrial and field
operations or because the logic is to capture
data and or timeline info

7EPC as a Code
- As there is nothing in front of the Header, the
set of - header codes defines the total system space
8EPC Connectivity Model
- All tags have to be compliant
- Applications have to be within the prescribed
domain
9EPCglobal Standards RFID Systems Architecture
10ISO/IEC JTC1/SC31Support for Unique Identifier
- EPC is one of a number of such codes
- ISO/IEC 18000 series have air interface commands
to read blocks 1n - The data protocol standards have an application
command to read the first object - Therefore can support
- unique identifier
- unique identifier attribute (concept close to
EAN.UCC Composite Symbology) - have option for directory and no-directory
structure
11ISO/IEC JTC1/SC31 Logical Tag Structure
12ISO/IEC Air Interface Data ProtocolSystem
Information
- System information is like Function Code 1 in
UCC/EAN 128, except many times more powerful - This provides a protocol level - not data -
method for managing the interface between
application and RF tag, and includes - Application Family to enable a subset of RF tags
to be in the communication channel - Data Format to specify the interpretative nature
of the encoded bytes on the RF tag - Access Method to create a logical structure of
the bytes encoded on the RF tag
13ISO/IEC Air Interface Data ProtocolSystem
Information Application Family
- Addresses real need to manage the transactions
across the air interface - with large population of tags
- where there is a risk of different types of tag
being present - To be compatible with smart card rules (SC17),
RFID for Item Management has 60 Application
Family codes - Application Family codes to be allocated to focus
on a meaningful subset within the system, thus
excluding RF tags from other systems - So far only 14 codes have been assigned covering
all major RFID for Item Management applications,
leaving 75 spare capacity of the initial block
14ISO/IEC Air Interface Data ProtocolSystem
Information Data Format
- Full feature - any combination of Object ID
- Application specific to include
- EANUCC
- Data Identifiers for primary industry e.g.
Automotive - IATA for baggage handling and freight
- Universal Postal Union
- ISO/IEC 15459 unique identifiers
- Blood transfusion (ISBT)
- EPC Global?
- The list can be extended to bring RFID benefits
to different applications without abandoning
legacy data
15ISO/IEC Air Interface Data ProtocolSystem
Information Access Method
- Access Method specifies the literal structure of
bytes on the RF tag - Access Methods defined
- no directory
- directory
- self-organising tag (near future development)
- data sensory information (near future
development) - Future developments are dependent on new
functionality and application requirements
16ISO/IEC Data ProtocolObject Identifiers
- Object identifiers used for selective read /
write - Based on ISO/IEC 9834-1 established rules and
structures - ISO/IEC 9834-1 allows systems to define objects
to any level of granularity - just need an object
ID - The object tree ensures uniqueness of objects
- Therefore, possible to encode different data,
including closed system objects with no risk of
corruption - Extension techniques make the system totally
expandable - It would be relatively easy to accommodate an EPC
code
17ISO/IEC JTC1/SC31 Approach to Legacy Data Formats
- Can accommodate EANUCC SSCC for transport units
- no need to change data only to migrate data
carrier - IATA may continue to use its bag tag Id and other
attribute data - ISBT may continue to use its alphanumeric 14
character code for the blood transfusion service - Various other ISO formats can be supported that
enable RFID or alternative data carriers to be
integrated - New data formats have been accepted from Japan to
support new applications. This type of process
will continue e.g. US DoD has a different request
in the pipeline
18JTC1/SC31 RFID For Item ManagementAn Integrated
RFID System
- ISO/IEC 18000 air interface supports legacy and
provides a bridge for future code structures - This includes anything developed by EPC Global
- ISO/IEC 15961 15962 data protocol supports
unique identifiers (legacy and new - like EPC),
and attribute data in a seamless manner - Together they are an integrated RFID system
supporting - efficient select of relevant tags, allowing
different applications to be supported - efficient support of different data and different
formats completely unambiguously
