...business provide such serve for customers? by cutting down the product cost and selling cost RFID(Radio Frequency IDentification): Introduction:is the wireless use of electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to objects. How does RFID work? the tags contain electronically stored information. Some tags are powered by electromagnetic induction from magnetic fields produced near the reader. Some types collect energy from the interrogating radio waves and act as a passive transponder. Other types have a local power source such as a battery and may operate at hundreds of meters from the reader.Unlike a barcode, the tag does not necessarily need to be within line of sight of the reader and may be embedded in the tracked object. Recycling the RFID chips we give the each customers a coles card like memberships card, everytime the customer bring a chip, we give them a point loyalty point, when the customer gets 500 points,...

...scanning antenna; it detects the activation signal and can transfer the information data in holds to be picked up by the scanning antenna. The advantages of replacing barcodes with RFID are 1) RFID tags can be read from a greater distance than barcodes. 2) RFID tags do not need to be positioned in a line of sight with the scanner. 3) RFID tags can be read at a faster rate than barcodes; as approximately 40 RFID tags can be read at the same time. 4) RFID tags can work within much greater distances; Information can be read from a tag up to 300 ft. 5) RFID tags are read/write devices. 6) RFID contains high levels of security; data can be encrypted, password protected or set to include a ‘kill’ feature to remove data permanently. 7) RFID tags carry large data capabilities such as product maintenance, shipping histories and expiry dates; which can all be programmed to the tag. 8) Once these are set up; it can be run with minimal human participation. And lastly 9) RFID tags are more reusable and rugged as a plastic cover protects them. The disadvantages of replacing barcodes with RFID are 1) RFID involves assembling and inserting a computerized chip; which works out to be more expensive. 2) RFID readers’ struggle picking up information when passing through metal or liquid. 3) Reader collision can occur where two signals from different readers overlap and the...

...When I entered the marvelous piece of work, the second thing I noticed was how tall it was, and how far it went in distance. This bridge has such a rich history behind it, and how it got its red color. The bridge stretches across the ocean 1.7 miles, exceeding the height of 746 feet, making a road for travelers and workers leaving and arriving the city. The orange color of the bridge is a key factor many people recognize that make the bridge special. “Consulting Architect Irving Morrow selected the distinctive orange color because it blends well with the span's natural setting as it is a warm color consistent with the warm colors of the land masses in the setting as distinct from the cool colors of the sky and sea. It also provides enhanced visibility for passing ships” (Golden Gate Bridge, 1). The bright, orange, tall pillars holding up this magnificent bridge was a sight for sore eyes. Stretching for miles, the bridges pillars rise and fall giving the structure a unique build. The bridge connects two pieces of land, San Francisco and Marin County. Walking through the bridge, stopping and knowing how much history this structure has and how much time, money, and energy was spent made me feel privileged to be able to see it. ...

To my immediate right, there is a small, round, little hut which is a cafe known as Bananazen. On the outside of it there are various pictures of fresh fruit. There are also many green, six- seater tables outside of the cafe which are covered by large white umbrellas. Looking straight ahead and down there are multiple levels of grey concrete stairs leading down to the avenue. There are also more tables. Overhead there are many concrete beams connecting the two buildings. They are literally joined together. These are very angular and run diagonally across the buildings.

Once I reached his house, he told me that we could go cycling. As it was a school holiday, the beach was packed with people. The sky was clear blue. Occasionaly, we could hear the airplanes soaring above our heads. The Airplanes made white lines around the sky, filling the sky with beautiful patterns made by the white lines. As we started walking to our right, the hustle and bustle of a Bicycle Rental Shop could be heard. Smells of the aroma of mouth watering food could be smelt from a distance. When we entered the shop we were greeted by sales assistants standing by the door. One of the sales assisstants took us to the mountain bike section. As I entered the section, I was amazed by the sight. From head to toe were colourful bikes lining agaiinst the walls. Small bikes, medium bikes and large bikes were piled against the wall. I chosed a ruby red bike and my Uncle chose a blue bike. As we had a day rental, we decided to cycle to Changi Beach and East Point. I hopped on my bike and started to cycle. along the way we passed many shops selling food, drinks, children playing in the sea or building sandcastles. The bicycle trail winded further East. There was a part where the bicycle trail winded near a pach of the beach and we could see the clear blue water rising on the beach and lowering back down into the sea. as it rised,...

...I could read the sign in the distance, Louisburg and Ottawa Next Exit. I thought to myself “Just a little bit and we’ll be there in no time”, knowing I was already a third of the way there. Still my emotions ran high as sweat began to gather on my hands as I gripped the steering wheel while my other hand stood ready to shift into a lower gear. My eyes darted up and down, frantically checking to make sure I wasn’t speeding. As I looked down to check my speed again, I could’ve sworn my heart stopped beating as I looked back up to see two navy blue cars sitting on the side of the highway. All I could say at that moment was “Ah Sh*it, that’s Not good, not good at all”. It seemed to be just my luck that of all the places in Miami County the state troopers decided to sit along the highway I was driving on. Now my brain was being bombarded with a million questions of what might happen if I get stopped. “Would I get arrested”? “What would my dad do”? “My Mom”? Would I really lose my license for the rest of my life? My whole life would be ruined if my license was taken away. How would I get around on my own? I quickly dismissed the thought and told myself to stay focused on getting passed the cops without any problems. Time seemed to slow as the truck drew...

...Aylin Vargas English 1301-416 Allegory of the Cave Annotation The son of a wealthy and noble family, Plato (427-347 B.C.) was preparing for a career in politics when the trial and eventual execution of Socrates (399 B.C.) changed the course of his life. He abandoned his political career and turned to philosophy, opening a school on the outskirts of Athens dedicated to the Socratic search for wisdom. Plato's school, then known as the Academy, was the first university in western history and operated from 387 B.C. until A.D. 529, when it was closed by Justinian. Unlike his mentor Socrates, Plato was both a writer and a teacher. His writings are in the form of dialogues, with Socrates as the principal speaker. In the Allegory of the Cave, Plato described symbolically the predicament in which mankind finds itself and proposes a way of salvation. The Allegory presents, in brief form, most of Plato's major philosophical assumptions: his belief that the world revealed by our senses is not the real world but only a poor copy of it, and that the real world can only be apprehended intellectually; his idea that knowledge cannot be transferred from teacher to student, but rather that education consists in directing student's minds toward what is real and important and allowing them to apprehend it for themselves; his faith that the universe ultimately is good; his conviction that enlightened individuals have an obligation to the rest of society, and that a good society must be one in...

C 515A “See also, then, men carrying past the wall implements of all kinds that rise above the wall, and human images and shapes of animals as well, wrought in stone and wood and every material, some of these bearers presumably speaking and others silent.” “A strange image you speak of,” he said, “and strange prisoners.” “Like to us,” I said; “for, to begin with, tell me do you think that these men would have seen anything of themselves or of one another except the shadows cast from the fire on the wall of the cave that fronted them?” B “How could they,” he said, “if they were compelled to hold their heads unmoved through life?” “And again, would not the same be true of the objects carried past them?” “Surely.” “If then they were able to talk to one another, do you not think that they would suppose that in naming the things that they saw they were naming the passing objects?” “Necessarily.” “And if their prison had an echo from the wall opposite them,...
