Bar codes : A bar code is a strip of bars and gaps that represent numbers, typically encode a serial number or SKU (Stock Keeping Unit) to identify a class or a type of product.
RFID a definition : RFID is a wireless AIDC (Automatic identification and data capture technologies) use to track and manage items with minimal (human) intervention. RFID is a system that involves electronic tags containing data encoded (e.g. identification) onto a integrated circuit (IC). A device (reader) sends an electromagnetic signal to the tag. The tag transmit its code when a signal is received from a reader
Type of tags : RFID Tag also called a transponder is a device attached to or embedded in a physical object to be automatically identified. The transponder components are a integrated circuit (chip), a antenna and the substrate (support).
- Passive tags : not equipped with a battery. They are activated by a reader.
- Active tags : equipped with a battery which that amplify the signal transmitted back to the reader.
- Semi-passive tags (also called battery-assisted passive tags or BAP) : equipped with a battery which energizes built in sensors.
Advantage of RFID over barcodes:
- Does not require a line of sight
- Multiple readings at the same time
- Read and write functionality
- Superior storage capacity
- Serialization (unique identification – at the product level – not at the SKU)
- Can operate in harsh environment
Access card : equipped with HF (High frequency) passive RFID tags. (also called smart Card identification)
Automated payments : equipped with LF (Low frequency) passive RFID tags. (e.g. EZ-Pass)
