I'd love to see this fleshed out more.
Right now spell chips seem a bit fluff specific, the circumstance bonus is a nice touch. The 1% discount on recharge is a bit cars salesmen-esque.
I haven't played enough, especially at higher levels, to understand balance well.
Maybe an archtype or a feat that lets you remotely use spell chips at the expense of a spell slot of equal level maybe eventually 1 level lower with a minimum of level 1 spell lot.
More correlation between computer tier and spell chip level to keep costs up.
Some sort of DC
like I said the balancing is beyond me.
