I predict that in the future this part of the mass, the offering basket WILL go away.
This is more or less a generation thing as well. The older generations which more likely than not do not have a computer still do the putting into the basket.
Even for myself I am taking a closer look at giving online and by the fall most likely doing it.
We pay all our bills online but every Sunday morning it is a ritual to write the check, put it in the basket, put the amount on the outside, and take it to church.
