If you have a KTTW card, it works identically to the MB and has all the same features (except the tracking), so yes, CM can scan for EMH. They've scanned ours successfully for early EMH, although they usually give us a confused look of "what is this?" first. For ride photos, you just have to tap one on the Mickey head to have it added to your account. Park photographers can tap them just like they tap a MB. For charging privileges, you usually have to tell the CM at retail checkouts to "press the MB button", because they think it's a credit card or gift card. A couple weeks ago, one said they had never seen it before and thought it was the coolest/latest thing.
