RFID vs NFC RFID (Radio Frequency Identification) is a tagging technology that is gaining widespread attention due to the great number of advantages that it offers compared to the current tagging technologies being used today; like barcodes. Near Field Communication, or more commonly known as NFC, is a subset of RFID that limits the range of communication to within 10 centimeters or 4 inches. RFID uses radio frequency waves that are either passive, active, or a combination of both. Active RFID tags have a power source that helps extend their range even further while passive devices rely on the energy that it receives from the interrogating device to send its own information. Among the advantages of RFID is the very small size of the tag that made it possible to be used with small products or to be hidden away neatly. Another excellent advantage is that it doesn’t need a direct line of sight for the information to be read. This is very desirable in baggage tracking application where speed is very essential. RF waves are used to transmit information across very long distances, and RFID is no different. The RF waves can reach very long distances especially when powered. This kind of range is very desirable in certain applications like animal tracking where the animal being tracked might move a couple of kilometers. But this type of range is not desirable in applications like cash cards or passports. Malicious people can receive your information and clone it into another tag and use it for themselves. This is where NFC comes in. Objects that are tagged with NFC are usually passive...
Yay, new site launched! myAppalogues – App-based electronic catalogues.

“The only way to achieve the impossible is to believe it’s possible.” – from “Alice in Wonderland” Eduardo Saverin – Facebook legend living in Singapore Tham Yuen-C Straits Times Site’s co-founder set up a software development firm here last year, but has maintained a low profile. The other Facebook legend – the one who fell out with co-founder Mark Zuckerberg – has set up a software development company in Singapore. Mr Zuckerberg is chief executive officer of the world’s most popular social networking site. His former collaborator, Mr Eduardo Saverin, 28, is one of three people behind Web technologies company Anideo, with offices in Singapore and Miami, Florida. The Brazil-born billionaire is said to have been living in Singapore since last year, and the Singapore outfit of his firm was registered under his name in October last year. His two partners are fellow Harvard University graduates, one of whom had worked with him on a job search site in 2005. Since technology site TechCrunch posted a blog last Thursday about him being in Singapore, netizens – here and abroad – have been speculating about his whereabouts. A film, The Social Network, based on the story of the two co-founders, is currently showing in cinemas around the world. Mr Saverin is portrayed in the movie as the more affable and charming character, in contrast to its depiction of Mr Zuckerberg as a socially inept geek who is also the more cunning of the two. Mr Saverin was Mr Zuckerberg’s partner in 2004 when, as Harvard students, they started thefacebook.com, a website that evolved into Facebook. But the duo fell out...
