His other post says he can read the tags through the case. @johnrgood, The Alpha may or may not work through the case. If you've requested one then you'll have to test it and let us know as @Memnoch says. Personally I think you're better just making the case thin or putting a hole right where your sweet spot is. This would make it an order of magnitude easier to use the ring for phone unlocking because you'd have a physical location to aim for. This would be easier to use than the sweet spot stickers and would work well with the Classic ring.
