ISO 18000 – Is the « key » RFID technology standard
The global home for standards is the International Standards Organisation (ISO).
Although the ISO process is by its nature long, involving six stages and several rounds of voting that are conducted on an international level, it does have the positive side that when a standard has completed these phases it truly does have an international acceptance.
ISO18000 describes the standard communication interface between an RFID tag and reader. (The Air Interface)
ISO18000 is very broad in its coverage. It has several parts, each covers different RFID frequencies. Part 3 covers 13.56 MHz and Part 6 covers UHF.
ISO18000 covers all Classes of RFID tag – Read only, WORM, Read/write etc.

RFID Technology Standards ISO18000What IS standardized ?
defines 3 things :
• Physical Layer• Commands• Anti-collision
All these relate to the “Air Interface” between the reader
and the tag
October 05 - 13
Physical Layer
Must standardize :* frequency* coding (whats a “0” whats a “1”)* data rate

RFID Technology Standards ISO18000What IS NOT standardized ?
Security (EAS) not specified in ISO18000 Data structure not defined Memory size not defined Additional proprietary commands
October 05 - 17
Library application standards : Future work - Security ?
Library Security (EAS on tags)
Defines the security mechanisms.
Should this be standardized?
What levels of security are necessary?
October 05 - 18
Library application standards : Future work - Data Structure
Data Specification
Defines the length, structure and position of Library data on the tag.
1001000111000001100111
DATA STRUCTURE
October 05 - 19
Example: EPCglobal data structure
Version 1.1 specification completed
Option of 64 bit or 96 bit EPC Codes
Data includes:
Header : defines length and identifier type - allows compatability to other numbering schemes, GTIN (global trade item number), GLN (global location number) etc.
EPC Manager : a code signifying the company or organisation managing the numbers in the subsequent fields.
Object Class : a code signifying the product type. Serial Number : a unique identifier for each item within a product type
In addition to the EPC unique identifier, some tags will have more memory space for User-defined data.
October 05 - 21
IC complexity drives tag cost
Chip (IC): less than 0.04% of the area,but 60% of the cost, of a tag
October 05 - 22
Strive for efficient memory use.
With 64 bits of memory, which is a very modest size of memory, you could program 18,446,744,073,709,551,616 different tags all with a particular unique number.
Or with 96 bits of memory, you could program 79,228,162,514,264,337,593,543,950,336 different tags all with a particular unique number.
October 05 - 23
Considerations when working on Data Standards
Simple Message: THE BIGGER THE HOUSE, THE MORE COST, THE MORE MAINTENANCE.
• The same is true for Tag ICs• Complexity/Memory size is not free
Carefully evaluate how much memory you really need
