If this sounds like pay it forward well its not exactly like that.It's pay yourself forward.
For those who process credit cards it means that when you cannot access your server (due to signal loss)you can still swipe cards and later download the info when the connection is good.
For many decades now this was only done with wireless credit card machines that charged a lot of monthly fees-Now you can do it on your smart phone.
This is big news and it works well.
say your phone is in a NO service area (some of you city folks may not know this exists) this means the connection is so poor the phone cannot send the data.You still may be able to talk but the credit info say on the square reader is stuck in spin mode.
With the square reader you can now go into your account and put it on store forward and that means you can take acards and when you get into a better area connection wise it sends the data and you are paid.
Now I should metion that this comes at some risk as the cards cannot be verified so you could take a bad card and it will be your loss.
You can now do this with the square and a smart phone-other readers should fall into line soon.
