How To Put Invite Codes on Business Cards

Moo have an api if you wanted to automate the entire process. Sometimes however going all manual is faster.

For example, I wanted to print all my unread instapaper articles into a book. Writing a script to do it would have taken a while so I kept putting it off. In the end I copy&pasted manually into a word processor and it only took an hour.

Three months later I'm still waiting for the book to be delivered by LuLu, who also don't reply to customer support emails.

Nice, but why not just use imagemagick?

It could be generated from a script that is as long as his script to create some keys.

We just had to do this, but shied away from the variable data printing, which was pretty expensive compared to getting a huge batch of identical cards (10x cheaper). We added the codes with transparent sticker labels. We had to affix them ourselves, but they look almost as good.

Also, we used Xyzzy to generate pronounceable codes. The 10-character ones were the most fun.

I would use LaTeX.

This reminds me of a wedding RSVP rails app I made two years ago. I did pretty much the same rsvp code generation approach but I found it helpful to store the RSVP codes to a database and use validates_uniqueness_of :rsvp_code to enforce the unlikely situation that no duplicate codes were generated.
