I've seen people awkwardly put a phone number into their cell phone and it makes you wonder if they were really putting it in or faking it to get rid of you, so a card (whatever you call it) with your number and an email address can be a resource to use more as an outreach tool in the community or at a school for instance. And by the way there are still kids/people that do not have cell phones, it's not a myth, they do exist. The parents of your students hopefully already have your number. I think these cards are more useful for outreach. I have heard stories and stories of people that have been out of church for a while and wanted to "get back" and found a card or pen in a drawer that someone gave them and they go to that church. You know just saying. I don't use cards but they are useful.

Haha, wow, it amazes me that people do not read the whole thing then take the time to post a comment bashing it. Nice. I love sarcasm by the way. Good job Tim.
