It's been over a year since I posted about Rhombus, but I've finally got an update.
I've also used RhombusLib to create a for-pay Android app AgeChecker to read drivers licenses to verify someone's age. I hope to sell this to a few liquor stores and bouncers. There are dedicated hardware terminals that do basically the same thing which sell for anything between $200 to more than $400 apiece.
I mentioned in the previous post that Rhombus can read track 1 with a shim to offset the card. I've discovered a cheap and easy source of shims. Those twist-ties from garbage bags do a pretty good job, though not perfectly precise.
