ISO18000

• Covert RFID needs in
• Long distance detection
• Unique ID
• Inventory
• Data Storage (ISO15961)
• Multiple frequencies
• 125KHz, 13.56MHz, 433MHz, 900MHz, 2.45GHz

Auto-ID Class 0 and 1

• Covert RFID needs in
• Long distance detection
• ePC code
• Inventory

UID vs ePC

• UID (ISO18000)
• Fixed size for each 18000 (40 or 64 bits)
• Accessible in Read Only (IC programmed)
• Inventory algorithm linked to the UID size
• Uniqueness guaranty by single source IC fondery
• ePC
• Variable size (64bits, 96bits, )
• Can fully support the ISO15963
• Programmed on the supply chain
• Inventory algorithm not linked to the ePC size
• Uniqueness guaranty by EAN/UCC codification
  scheme, but final user has to managed it.
