Attribute	Barcode	QR code
Data capacity	Can store up to 24 characters	Can store up to 2000 characters
Reading requirements	Require line of sight	Require line of site
Durability	Paper labels may subject to wear or damage
Efficiency	Only a single bar code can be scanned one at a time.	Are more limited than bar codes as scanning process will take longer, depending on the amount of data
Read-write	No read-write	Read-write is limited as new printing label is required
Security	Little to almost none security, which makes forgery easy	The data can be converted so, it is not really recommended for large scale tracking systems
Cost	basically free when printed during packaging	1 to 10 cents for paper label

PROS & CONS

	Pros	Cons
Barcode	1) Simple solution 2) Can be automatically scanned	1) Numbers can overlap/clash 2) Hard to continue data with other system 3) Adding additional numbers later can cause problems if design is not well planned 4) Insecure: Numbers can be guessed 5) Requires proprietary scanning hardware and software
QR Code	1) Can be automatically scanned 2) Can sometime be scanned by smartphones and tablets with proprietary software	1) Numbers can overlap/ clash across teams/dept./existing software 2) Hard to combine data with other systems 3) Adding additional numbers later can cause problems if design is not well planned 4) Insecure: Numbers can be guessed 5) Requires proprietary software to view asset data
