Respond to following 3 following forums on (What is the one most important comparison between RFID and bar codes this year?)on100 or more words.  Responses should be a minimum of 100 words and include direct questions.

1. The increase of required goods to be tracked both from outbound to inbound delivery requires timely tracking and accurate information. RFID tags provide an accurate of assessment of items in transit from start to finish. Tracking items are essential to the success of the supply chain and provide a visibility for transportation mangers on a global scale. The clear and concise difference between bar codes and RFID tags, simply stated is the level of accuracy. Bar Codes provide an abundance of room for error, which in todays high demand economy is simply unacceptable. Bar codes have critical limitations that prevent the transportation manager from tracking multiple items. RFID tags can be utilized to track multiple shipments from different nodes, while providing real time location. Organizations must determine the best method of tracking equipment while applying factors like cost, distance and mode of transportation.
The supply chain requires clarity throughout the distribution process. RFID readings have proved to be more effective and provide a higher level of accuracy when compared to bar codes. Although, studies show RFID tags are more accurate both leave room for human error. RFID tags require a degree of programming which can be done improperly. Bar Codes under high volume areas require scanners to react with diligence and accuracy. Overall, both tracking systems have areas of concern from a tracking prospective, but studies show that RFID tags provide a higher level of accuracy. The article Comparison of Reading Speed of Bar Codes and RFID conducts a small case study that displays the level of human inaccuracy that negatively impacts accurate bar code readings.

2. They use of RFID (radio-frequency identification) and the bar codes are very important in the logistics world. Although, RFID technology has a lot more beneficial to use compare with the bar codes. Comparing the two seem almost unfair because due to all the advantages that the RFID has to the bar codes. Lets begin RFID can scan multiple items at once, track at a greater distance based on the frequency which can be high, low and ultra-high. The RFID price will certainly vary based on the frequency level which is understandable according to its quality. For instance, the U.S. Army uses a tag, electronic identifier which uses radio waves to transmit information from the RFID tag to a computer or a receiver data which in order word is the same technology or system. Furthermore, RFID provides more security than the bar codes by being a lot more complex to reproduce as the bar code can. Also, RFID can be used to monitor the quality of wine from the time it leaves the winery through to the distribution center and the retailer (Trepagnier, pg. 2). These are just a few advantages of the RFID compare to the bar codes.
Although, many people might assume that the bar codes are not as effective as the RFID but it may not be the fact. Briefly, Barcoding uses a scanner with a beam of light to read the black and white lines of a barcode. The scanner includes a sensor that creates a signal from the reflected light and a decoder then translate the signal to a computer (Trepagnier, pg. 3). The barcode reduce human error which is important to be noted and can even be more precise than the RFID since each box or item got to be individually scan. The barcode saves resources by contributing in supply economy. While RFID can scan multiple pallets however the barcode accuracy is more reliable because one can either scan or not scan an item which will be reflected in his inventory. One can assume that the RFID might miss something which is almost impossible for the barcode. Obviously, both systems have their advantages and disadvantages and at the end it will depend on preferences, and cost effectiveness.
