When technology just works

Today I needed to visit a medical specialist for collection of something. I had to pay $250 as my insurance did not cover. I sent a check as requested however today they had not record of receipt. Not wanting to write a second check and then find they cash both, I logged onto my online banking right there with my iPhone (miracle I could remember my login and password as all important logins like this are different and normally I need my notes) and I’m able to confirm deposit and even view a scanned copy of the check. Confirming the date they are still unable to find. I’m able to use an office computer and print out this confirmation to show them proof of payment.

The technology of the iPhone and the thoroughness of my bank online check verification solved the hassle, simplified the confirmation and greatly reduced the stress of the situation. At T-2 days the technology worked and I was most grateful.
