[quote=@rechonq]If the sigil is tattoed to him would he need to tough with his hand or anything to activate it? Or would he just have to think of his dream and it would activate?[/quote]
Thaaaaaat is an excellent question! I think he'd just have to focus his thoughts on the spot where the tattoo is, with specific intention -- otherwise it would activate whenever he got excited, haha!

[@Dud] The keycard sounds like whatever it can do can be done through technology, however mystical the secret pathways might be -- I'd leave that as a regular old keycard. :)

The calculator is a really interesting idea. Keep it as an enchantment -- no batteries necessary -- only I don't think a company would simply hand it out, just given the fact that this one may be the only one in existence. Unless whoever gave it to him has an ulterior motive. ;) I'm not saying get rid of it, but rather he might have obtained it somewhere else. Unless the ulterior motive stands, in which case you're good to go.

There's a lot of confusion about sigils -- I'm adding stuff to the description to try and clarify it. A sigil is a drawing or an engraving, nothing more. You can memorize it and draw it yourself on a piece of paper (or touch an engraving, etc) and then activate it to produce a temporary magic spell. The exact drawing that is the Sigil of Accountancy might reveal money-related information to the caster depending on the question he holds in his mind. But really, you can decide what it does, exactly, when you get to a situation where you want to use it.

So after this long-winded thing, I'm essentially saying the keycard is not enchanted, and you're approved. :D
