I just love all the new plug ins for the iPhone–maximizing it’s use as a powerful handheld computer.
Whether it’s attachments for talking fingerprints and iris scans (from MORIS–that I wrote about in a prior blog) to running credit card payments (from Square), the iPhone has amazing versatility and almost endless practical use–as we are all coming to learn and enjoy.
With Square, the simple credit card reader plugs right in to the headphone jack.
Then by simply launching the app, users are ables to run payments through just as any professional business would.
Simply type in the dollar amount, sign with a finger, send a receipt via email, and even display the GPS of where the charge was made–all done by mobile device and wirelessly.
According to BusinessWeek (10 Feb 2011), smart-phone card readers will process $11 billion in payments this year and this is projected to rise to $55 billion by 2015.
“Square charges merchants 2.75 percent of sales plus 15 cents per card swipe,” but in turn creates new opportunities to sell remotely and transact business seamlessly.
It is only a matter of time before hard currency becomes obsolete as electronic payments becomes easier and matter of course.
My pockets are already empty and I do not miss the greenbacks–bits and bytes registering securely in the bank are more than fine by me.
Next up as for attachments to the iPhone–medical scanners (the possibilities are endless, but some examples could be for diabetes metering, X-rays, and much more.)
