Serialization Approaches

Implementation Strategies

SERIALIZATION MODELS:

UNIT-LEVEL SERIALIZATION:
• Each unit gets unique ID
• Maximum traceability
• Highest cost
• Required for pharmaceuticals
• Example: Each bottle has unique serial

BATCH-LEVEL SERIALIZATION:
• Each batch gets unique ID
• Moderate traceability
• Lower cost
• Common in food and beverage
• Example: All bottles in batch share ID

LOT-LEVEL SERIALIZATION:
• Each production lot gets ID
• Basic traceability
• Lowest cost
• Minimum compliance
• Example: All products from run share ID

HIERARCHICAL SERIALIZATION:
• Multiple levels of IDs
• Unit → Case → Pallet → Shipment
• Flexible tracking
• Optimized logistics
• Example: Nested serialization

SERIAL NUMBER FORMAT:
• GS1 standards (GTIN + Serial)
• Company-specific formats
• Random vs. sequential
• Encrypted vs. plain
• Alphanumeric vs. numeric

Data Carriers

Physical Encoding

DATA CARRIER OPTIONS:

LINEAR BARCODES:
• 1D barcodes (Code 128, Code 39)
• Low cost
• Universal compatibility
• Limited data capacity
• Requires line-of-sight
• Common use: Shipping labels

2D BARCODES:
• QR codes, Data Matrix

• Common use: Unit serialization

RFID TAGS:
• Passive (no battery)
• Active (battery-powered)
• No line-of-sight needed
• Bulk reading
• Higher cost
• Common use: Pallet/case tracking

NFC TAGS:
• Near Field Communication
• Smartphone readable
• Short range
• Medium cost
• Common use: Consumer engagement

PRINTED ELECTRONICS:
• Printed circuits
• Low cost potential
• Emerging technology
• Future applications

GS1 Standards

Global Standards Framework

GTIN (Global Trade Item Number):
• Product identification
• 8, 12, 13, or 14 digits
• Worldwide unique
• Encoded in barcodes
• Basis for serialization

SSCC (Serial Shipping Container Code):
• Shipping container identification
• 18 digits
• Used for logistics
• Pallet and case tracking

GLN (Global Location Number):
• Location identification
• Parties and locations
• 13 digits
• Supply chain visibility

GRAI (Global Returnable Asset Identifier):
• Returnable assets
• Pallets, containers, kegs
• Asset tracking

GDTI (Global Document Type Identifier):
• Documents
• Invoices, orders, certificates

GS1 SERIALIZATION:
