Catholic Church - Is their an app for that?

Why is it taking the Catholic church so long to adopt technology in their environment?
Let's start with donations.
Yesterday, they had the bishop's lenten appeal. They pass out envelopes and pencils for the donation commitment.
I believe, that if their were an "app" for that, we could generate more funds for them. The way it would work is this:
Each church as their own "App" for Iphone or Blackberry. When you walk in, you use the app to make a donation while there in church. For myself, when I heard about the envelope process I cringed, I just wanted to pull out my blackberry, launch an app, make the donation then and there and be done with it. Now I am going to get something in the mail, have to fill it out and send it back. Seems to cost more money.
Furthermore, the church should adopt more video delivery of messages in the building. Monitors should hang on the sides that broadcast the church bulletin (bonus to those that have taken an ad out on the back of the bulletin) and the monitors should be used so that the homilies finally use power point in order to keep the speakers on track for their message. After all it is all about the delivery of the message.
