New Hardware: Access Control Systems
2009-06-18 19:06:00 Security card access systems provide total-control access to buildings or certain areas by limiting admittance and/or setting time-of-day restrictions. With the KeyScan Access Control System, an individual can pass their contactless or proximity access card in front of the card reader where the reader will decrypt the "max secure code" and authenticate it with a 3-pass encryption/decryption to unlock the algorithm. The credential is then sent to the access control management software to verify the access availability through KeyScan's proprietary 36-bit Wiegand protocol. The K-SECURE Mifare credential provides anti-counterfeiting protection using Keyscan's Max Secure encryption technology on 'over the air' transmission between the reader and card.
Marketing Online Money Making Systems - Don't Get Distracted
2009-06-13 13:33:00 When we talk about How to Make Money on the Internet, one thing that is GOOD about the Internet is the availability of lots of free information. First of all there are free articles that provide all kinds of advice such as how to set up a web site, how to bring in traffic and in general how to be a success. Secondly, there are many just plain free offers for money making systems or methods and even free training telecasts. Usually, these come with an add-on offer, which is how the marketer makes his money. But you don't have to buy the offer (which you probably don't need anyway). So you often can get very useful and valuable products and advice for free.But on the other hand one thing that is NOT good about the Internet is that much of the information promoting Money Making Systems is hype! Almost all of the products offered come with wonderful claims on how much money you will make and how fast. I read one today which claimed that you would literally be making money the ...
