I Have the standard ring ,it works without the case but not with when I get the Alpha (larger) ring should it work with the case ?
It should, but you won't know till you try it.
not necessary... can you read the lager tag you received with you ring trough your case?
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.
