Barnes & Noble Inc cut prices on three models of its Nook e-reader and tablet devices on Sunday, ahead of the peak of the back to school season and amid speculation that rival Amazon.com Inc is preparing to launch a new version of its Kindle Fire tablet.
Barnes & Noble, which has said the Nook has allowed it to win 27 per cent of the US e-books market, said it had slashed the retail price of its Nook tablet with 16 GB of memory to $199 from $249. Amazon is the market leader with about 60 per cent of e-book and e-reader sales.
The largest US bookstore chain also shaved $20 off its 8 GB version of the tablet to $179. Barnes & Noble lowered the price of its Nook Color by $20, bringing it to $149, the latest reduction for that model.
The new prices went into effect on Sunday. Despite the popularity of the Nook devices, Barnes & Noble has had to reduce the price of various versions on a number of occasions to compete with Amazon, which is believed to be preparing to launch a new version of its Kindle Fire tablet. The earlier price reductions cut into Barnes & Noble’s earnings.
The company, which has bet its future on staking a claim in the e-books industry, reported lower-than-expected revenue in the fourth quarter and said Nook revenue fell 10.5 per cent.

The newspaper-style printing of electronic equipment has led to a cost-effective device that could change the way we interact with everyday objects.For a price of just one penny per unit the device, known as a rectenna, which is presented in IOP Publishing’s journal Nanotechnology, can be placed onto objects such as price tags, logos and signage so that we can read product information on our smartphones with one simple swipe. This type of technology, which is known as near-field communication (NFC), has already been implemented to allow fast money transactions; however, this new device could lead the way to large-scale adoption at a low cost.
The rectenna, created by researchers from Sunchon National University and Paru Printed Electronics Research Institute, could be implemented onto everyday objects so that they can harness the power given off by the smartphone’s radio waves and send information back to it via printed digital circuits.
It is called a rectenna as it is a combination of an antenna and a rectifier — a device that converts alternating current (AC) into direct current (DC). The rectenna was printed onto plastic foils in large batches using a roll-to-roll process at a rate of 8m min-1. Five different electronic inks were used and each rectenna had a length of around 1300 mm. The researchers state that the rectenna can harness power directly from radio waves given off by a mobile phone, converting AC into DC. The rectenna created in this study could provide at least 0.3 watt of power from an alternating current which had a frequency of 13.56 MHz.
NFC technology is very similar to QR codes, whereby users take a photo of a square-shaped bar code on a poster or advert using their smartphone. The difference with NFC is that items will contain a small computer chip or digital information, operated by DC power. “What is great about this technique is that we can also print the digital information onto the rectenna, meaning that everything you need for wireless communication is in one place,” said co-author of the study Gyoujin Cho. “Our advantage over current technology is lower cost, since we can produce a roll-to-roll printing process with high throughput in an environmentally friendly manner. Further, we can integrate many extra functions. ”
