Bracket International Case Study
1. By searching the Internet and library, summarize the advantages and disadvantages of RFID Systems. How does RFID compare to bar-coding? Did you find any RFID applications for services?
RFID has several advantages and disadvantages and some of them are:
Advantages:
• It may reduce operation cost in the long run.
• RFID Equipment damage occurs much less frequently as compared to other magnetic strips or bar code systems.
• An individual can potentially be identified and charged with right fare by simply carrying the RFID smart-card.
• RFID scan time is much less as compared to old fashioned bar code scanning time.
Disadvantages:
• Cost of diffusion and implementation for an RFID System can be high.
• RFID has the potential of seriously invading people’s privacy.
• RFID Technology involves software that allows each user to be identified by central database. Because of this, it is possible for hackers to attack the system easily.
• There is a possibility of poor read rate if the reader and receiver are not properly aligned.
• When multiple tags and readers are at work simultaneously, there is a possibility of having double charges.
Even though RFID Seems to be faster than bar-coding process but the comparison between the two shows the following:
• There is a big difference between the two systems for read range. For a passive Ultra High Frequency (UHF) for up to 40 feet and active RFID For up to 100 feet, there is no read range required in most cases but a bar code system requires having read range from several inches up to several feet.
• Read Rate: RFID can read anywhere from 10’s to 1000’s simultaneously and bar code system can only read one at a time.
• Identification: RFID can uniquely identify each item/asset tagged and bar code only identify the type of item i.e, UPC Code but not uniquely.
• Read/Write: Many RFID tags can read and write whereas barcode system can only read.
• Technology: RFID technology is based on radio frequency and
