Amazon has launched its digital currency Amazon Coins, allowing customers to buy apps and games in its app store and on its Kindle Fire tablets.
Amazon put 500 Amazon Coins, worth $5, into the accounts of all Kindle Fire owners on Monday.
One Amazon Coin is worth one cent and can be used to buy apps and games as well as for in-app purchases, for instance when someone is playing a game and wants to upgrade to a new level quickly.
The company also acquired Liquavista NV from Samsung Electronics Co to help them develop develop new displays for mobile devices.
Liquavista focuses on a technology called electrowetting, which it says makes displays clearer in all lighting conditions and can show video without using much power.
The technology can be used in mobile gadgets such as e-readers, smart phones, GPS devices, portable media players and cameras. Over the long term, electrowetting can be used in larger display products such as laptops and TVs, Liquavista said on its website.
