RFID Privacy and YouWritten by Rich McIver
Continued from page 1
Despite these and other such dangers, however, there are some steps being taken to mitigate these privacy issues. For example, a recent proposal would require that all RFID-tagged products be clearly labeled. This would give consumers choice to select products without RFID, or at a minimum to recognize that items they select are being tracked. For those unsatisfied with disclosure, there also exist a growing number of products designed to limit their exposure to RFID tagged products. One such product is ěKill Codesî a command which turns off all RFID tags immediately as consumer comes into contact with them, thus entirely eliminating effectiveness of technology. Another proposal, however, ěRSA Blocker Tagsî, try to address privacy concerns while maintaining integrity of product. Under this technology, item can only be tracked by that store's authorized reader, meaning that customers cannot be tracked outside of store in which they purchased item.
While some of dangers posited here seem far-fetched and unlikely, technology already exists and is developing rapidly to ensure that such hypotheticals can become realities. RFID tags have potential to revolutionize shopping experience by bringing us targeted products and allowing retailers and manufacturers to track purchases and shopper behavior more accurately and cost-effectively. The concern, however, is that if we are not aware and careful about potential abuses of such technologies early on, we may fail to incorporate them at a time when laws and mores of such a system are still developing, ultimately suffering consequences later on.

The Calling Card AlternativeWritten by Robert Mann
Continued from page 1
So here are steps you need to take to get best out of your calling card purchase: - Find a reliable website (this means no weird pop-ups, no advertisement of Viagra on website – you get my point). - Take a look at available calling cards and rates. - Check out any details of calling cards: usually, next to or underneath picture of calling card there is a link that will take you to a “Details” page. Look for maintenance fees, rounding, any other surcharges, expiration dates. - If you intend to make a lot of long calls over a short period of time, choose a card with a maintenance fee. This means that a certain amount will be deducted from your balance each week/month until you use up card. But if you plan to make so many calls, you’ll probably use card up by time maintenance fee is deducted. Calling cards with maintenance fees also tend to have lower rates. - If you use card just once in a while, choose a card with no maintenance fee. These cards usually have higher rates, but you don’t have to worry about your balance going down if you do not use card. - Look for a Customer Service number. Reliable companies have Customer Service, in case their customers have questions or problems.
After this, get card you this is best for your needs and wait for it to arrive in email. Unless otherwise specified, you should be able to use it immediately. Good luck!
