Apple mocks latest Android version's market share, again!!

RFID at its best

Always hated these big retail outlets like Dmarts or Reliance Fresh's, only for a simple reason, irrespective of what i have to buy & how much i have to buy, i had to pass through that whole long queue of people at the payment counter who had their shopping baskets full & sometimes more than one. So, i never preferred going to these places unless anything i wanted was out of stock with my nearest 'Kirana wala' guy, or unless i am getting heavy discount on items (which was a very rare case).

Once i wanted to have Kwality walls Disc ice cream cone which was only available with Reliance Fresh outlet in our area. So being helpless i had to go there & found my ice cream, now the thing i always hated (standing in that stupid queue for payment) was the next after taking the ice cream. Although it was a weekday & there were not long queue's on any counter, still that 2 or three person with 5 to 6 items in their shopping bag could be considered long for me as the product i was buying (ice cream) could have been easily converted to milkshake waiting in that queue for billing. Intelligently or luckily, i don't know, the outlet had the ice cream fridge near to the payment counter so thankfully i could keep my ice cream in the fridge itself untill it was my turn for billing. But till then i was embarrassed to every other customer who came behind me in the queue by telling them that this is what i have purchased & so i am standing this far from the person billing ahead of me. Meanwhile i was waiting in the queue (which was long enough) it suddenly struck my mind, why not have a shopping basket that could simply calculate the amount of my purchases & directly debit the amount from my linked bank account.
After doing some research whether it's possible, I came across the technology RFID.
It consists of two major parts, the receiver and the RFID tags itself.
Also came across many videos explaining the idea, but the best one i found is by this company Essen RFID. Here is the link to the video which explains the concept pretty well & also shows it's possible applications in different industry.
