RFID Technology—Introduction

Different Classes of Tags for Different Applications:

Tags play a key role in the ACID. There are 6 different classes of tags. This table summarizes each class

Comparison of Barcode and RFID:

Although barcode patented 1949 but it took a long time for industry to adopt the barcode. The following table summarizes the comparison of these two technologies:

Class	Progress
Class 0	Factory programmed Read-Only tags
Class 1	Factory programmed with minimum features for keeping price low but user can program it
Class 2	R/W passive tag with longer communication range than Class 1
Class 3	Semi-Passive R/W tag with on board power source
Class 4	Active adhoc R/W tag with on board power source
Class 5	Autonomous active R/W tag with on board power source
