ADVANTAGE

1. Barcodes use in the intelligent book finder system uses EPC over UPC.
2. The chip that is used is a tiny computer that stores a series of numbers unique to that chip itself.
3. The antenna in the chip and at the bookshelves can receive power, communicate and enables the RFID tag to exchange data with the reader.
4. The passive RFID tag is tiny size compared to the active RFID tag.
5. The passive RFID tag is more economically affordable compared to the active RFID tag.
6. The chip has the logic to tell itself what to do when it is in front of a reader

EPC	UPC
1. Contains more information: a) Header Represent a military UID or an FDA code, instead of a complete EPC structure. b) EPC Manager Number Identifies the company or company entity. c) Object class Similar to a stock-keeping unit (SKU). d) Serial number Identifies the item.	1. Contains only information of the manufacturer and the product codes. a) First partition Single digit that indicate the numbering system use to interpret the remaining characters. b) Second partition It is made up of five numbers that designate the manufacturer’s identification number. c) Next five digits It represents the item number.
2. It stores a lot more information.	2. It stores less information.
3. The total data-carrying capacity of an EPC number is from 32 to 256 bits long. This means that EPC can accommodate millions of trillions of possible number.	3. UPC can only accommodate 100,000 possible numbers.
