One Coin for All of Your Cards – Digital Card Device

Posted on


Coin is a credit-card size device similar to the Proteân Echo that retains multiple cards in its memory. As of November 2013, it’s currently in the crowd-source funding phase, but is reported for availability in 2014.

There are many card storage apps for the iPhone and other mobile devices. These will keep track of your card numbers and details. At many retail stores, the clerk will enter your number by hand (if you have it stored with these apps for easy retrieval), or bring it up by your phone number.

However, credit cards and some rewards cards need to be scanned. That’s where this device will be useful. Apparently it can mimic your cards through a dynamic magnetic strip. It’s programmed by scanning existing cards in the same way some smart Universal Remotes can learn from the original. After the Coin smart card is programmed, it can be swiped in a reader.

Security Risk

A potential security risk of this and other devices is that it may allow people to capture physical credit card data and then reuse it without the owner knowing their card has been stolen (since they will still have the original card in their possession. This could happen any time the card is out of someone’s possession for even a moment (at a drive through or restaurant for example). Most credit cards have a number of ways for merchants to know it’s the original card and you are the original owner (photo, signature, and computer chip).

Iowa City Tech Support and Services – A Preventative Approach

Posted on


The Technology Services Resource Group was founded in Iowa City by Greg Johnson in the early 1980s as Public Interest Computer Consulting (PICC). In the early 1990s, the name was changed to PC-DOC. By the year 2001, the name was changed to Technology Services Resource Group (TSRG) in an effort to convey the broad range of support available. Although services are provided beyond Iowa City, having a familiar domain name of Iowa City Technology Services helps to identify TSRG as a local resource.

Prevention Services

The term “tech support” is generally used to convey hardware repair or some other kind of computer help.

A “tech support” mindset is generally reactive rather than proactive in responding to computer problems. When something breaks, you call tech support.

However the term “technology services” can include not only problem fixing, but problem avoidance by offering services such as user training, implementing data backup plans, and installing antivirus and security software. Technology services can include integration of different devices (mobile, desktop, and other).

By contrast, tech support is usually there for you when things go wrong. Proper setup, support, and training should help avoid problems.

So, deciding on the name Technology Services, seemed to be a better fit.
