Your Next Credit Card May Be a Cell Phone.

08.4.10 - Credit Card

My wallet is pretty small. I don’t carry business cards because you can get my contact information from my LinkedIn profile, Facebook page, website or email signature. I don’t carry money because I have one rewards credit card that I use for everything.  If you don’t take credit cards, then I’ll go to the store around the corner that does. I don’t carry receipts because I scan them into Evernote and have them synced with my phone. I don’t carry pictures because I put those in Dropbox and can see them on my phone any time I want without the risk of losing them. I don’t carry health insurance cards, dental insurance cards, business cards from my doctor’s office, or membership cards from AAA or elsewhere, because I put all of that information into my contacts on my phone and leave the cards at home. I don’t carry a library card because the library staff can pull up my information based on my driver’s license. So I am left with my driver’s license and a credit card. It seems that if Verizon and AT&T have their way, I soon will be down to just my driver’s license.

According to several sources, Verizon and AT&T are working on a partnership to develop contactless payments from your cell phone. The financial website The Motley Fool has more information on the deal.  It seems there is no word yet on when this might be rolled out, or how they are going to fill my mailbox with pre-approved cell phone / credit card offers.

So what do you think?  Would you use a system like this?  Would you trust it?

4 Ways to Get Update Alerts From Sites That Don’t Have RSS Feeds

website alerts

RSS is a great tool for keep tracking of updates to a web site.  Twitter can be used in a similar fashion for those sites that announce updates via Twitter.  It's a sad fact, though, that not all websites have RSS feeds or Twitter updates.  Don't give up hope, though.  Here are four other methods for being alerted when a site is updated.

How to Find Out When a Page Was Last Updated

page update date and time

Have you ever been curious to find out when a web page was updated?  There’s a little trick that you can use to determine the date and time that a specific page was updated.  Simply type the following into your address bar, and then hit “Enter” on your keyboard:

javascript:alert(document.lastModified)

This only works on some pages, and your browser must be javascript-enabled for it to work.  If you want to automate this with a bookmark, WorldStart.Com has some instructions, which basically involves placing the above code in the address line of a bookmark.

In my experience, this isn’t foolproof.  A site needs to have date information contained in its code, either because the developer placed it there manually, or because the system upon which the site runs did it automatically.  When it works, though, it is a handy trick.

Green Tech to Save Some Green: A New Monthly Column

Green Tech to Save Some Green | 40Tech

Short of spending $18 billion of your hard earned cash on speculative research, there are things that each us can do to reduce our impact on the environment.  Yes, you can walk to work and stop using toilet paper, and those are certainly admirable and possibly uncomfortable efforts if combined, but let's be practical: most of us just aren't going to do that. So we wanted to take today to announce that 40tech will be starting a monthly column on environmental technology. We’re calling it Green Tech to Save Some Green. But wait! Didn’t we just say something about $18 BILLION on speculative research? Ohhh yes! Read on!

Our Favorite Finds, Coming Soon [Site News]

finding other content

Here at 40Tech, we don't have an exclusive on good content.  We spend time checking out many other sites on the Internet, and find all sorts of great stuff.  Some of that content might be from sites that you visit, but much of the content may be new to you.  Starting Monday, we'll be sharing our finds with you.  Our posts will be short, calling attention to the content on the original site.  If a topic interests you, we hope that you'll then go check it out in full detail at its source.

We have been publishing about three posts a week.  We're going to try to double that, so that we have our usual three "long form" posts each week, and three posts highlighting great finds from around the Internet.
