Need More Than Just an ID

  • Expanded memory capacity

Transaction history (e.g., pharmaceutical medicine)

Extended ownership description (e.g., airline luggage)

Content authentication (hash of legal documents)

Ownership Description

  • Ownership information (~ 512b)

Each ASCII needs 8 bits

Each Chinese character needs 16 bits

  • Applications

Freight items

  • Luggage

Post mail and packages

Human and animal ID tags

  • Patients tags
  • Students tags
  • Event tags

Transaction History

  • Tracking information (1K-2K)

Transactions from manufacturers, distributors to retailers, etc.

  • Applications:

Product history tracking

  • Pharmaceuticals, food, wine, cigarettes,

Anti-counterfeiting

  • Unique ID and logistic history for each

product

  • User verification on the spot, no need
  • f backend database

Even Larger Content Storage

  • Hash-of-content, or even content

information

One A4 page of English ~ 4K to 8K bits

One A4 page of Chinese ~ 8 K to 16 K bits

One passport-sized picture ~16K to 32 K bits

  • Applications

Machine automatic content reading

Authentication

  • Legal documents, such as certificate,

diploma, transcripts, etc,

  • Pictures, or finger prints for ID cards

  • MTP (multiple time programmable) logic-NVM

CMOS based NVM, up to 1K bits

Pro: No extra mask, low manufacturing cost

Con: Large footprint size

  • MTP Flash (E2PROM)

Up to 128K bits

Pro: small footprint size

Con: Higher manufacturing cost

  • OTP (one time programmable) NVM

Potentially can go beyond 128K bits

Pro: No extra mask, Low manufacturing cost

Con: One time programming

Novel RFID Memory Design

RFID with Secured Communication

  • EPC Gen-2 has little security

mechanism built in

Only 32-bit password for read/write authorization

Plain EPC ID stored and transmitted

Tags may potentially be cloned, intercepted or emulated.

  • Different levels of security

needed for various applications
