The Scenario that I am going to explain is the user paying for all their goods. What I am going to demonstrate is:
- The type of environments that this system is usually used in.
- The technology that will be used
- The various processes that will happen to purchase items (see the image on the left)
- Why this is benificial to the target audience (old people)
The Types of Environments
Imagine a busy supermarket, your local Sainsbury's, Tesco's or Asda. Shoppers in every ilse rushing around buying their weekly shop. With some of the larger stores on average having 30 isles, shelving above head height stocked to the brim with goods, loads of busy shelf replenisment staff, and the worst is yet you come! You finally finish shopping for the week and you head of to the nearest check out to find the queue is like the M25.
The Technology that will be used
One of the latest pieces of technology to hit the market is RFID, RFID is a small silicon chip that can store information about items, so not great for databases but great for things that could be found at your local super market shelf, Mars Bars, Cheerios, Bread... etc...etc (for more information click here: http://news.bbc.co.uk/2/hi/technology/6389581.stm ) So in essence you could store the bar code on this RFID chip and therefore remove the barcode, but then I can hear you say, why would you want to remove the bar code with this chips that cost more? Well simple, our idea encorparates the technological advances of RFID to remove the worst part of the shopping experience, the queing at the tills.
RFID readers are directional, which means that if we line the trolley with a couple of RFID readers facing intowards the trolley then any item that is put in the trolley can automatically be calculated removing the need for people having to queue to get their items paid for.
The Processes
In this example I will use one of our personas, Tony. So as Tony is doing his usual trip to his local Sainsbury's in his usual italian pin stripped shopping suit. He starts to throw in all the ingredients into his trolley that he needs for mama's secret recipe which he is planning on cooking later on tonight.
All the items that he has put into his trolley have RFID tags, so as he places them in his trolley the readers read the information of the item, and sends it to the trolley device which shows on screen the price and the nutrional information. Once Tony has finished his shopping trip he walks over the checkout and instead of tilling up he just walks past the tilling sensors that will automatically charge him through his store card. This means that he doesn't have to wait, it's like walking through an X-ray machine.
So... recapping quickly using bullet points:
- Tony adds an item to the trolley
- The trolley RFID readers pick up this new item, relays the information to the trolley device showing information on screen
- Tony finishes his shopping trip and walk through the tilling isle (without queuing)
- At this point the Trolley device has sent the information to the store charging/EPOS system that has taken the payment with the use of information of the store card that was placed into the trolley device.
Why is this Beneficial to Old People
Well as we know old people aren't the nimblest or quickest people in a supermarket. Firstly this technology means that - They don't have to worry about having to take the items out of the trolley
- Having to place items on the conveyor belt
- Bagging the items really quickly
- Hunting around for their card to pay for the goods
- Placing the bags back into the trolley.
Missing out these steps removes the need for physical strains for old people when shopping.
