The combination of Java JE2 ME and Open Ways' Crypto Acoustic Credential is sufficient security for Hinkmond Wong, as he attests in a recent blog. Wong includes a link to a HotelChatter post on concierge.com, which announces plans by a soon-to-open Holiday Inn Express Hotel & Suites property in Marion, IL to use guests' smart phones rather than key cards as room keys. He quotes the post, which says, "OpenWays uses a Crypto Acoustic Credential (CAC) and text messaging to securely deliver a unique acoustic key to the guest anywhere in the world. The CAC solution can be retrofitted to the major electronic locks on the market. It is compatible with all 6 billion mobile phones in the world, including all cell phone network technologies (GSM, UMTS, CDMA, 3GCDMA, 4G, LTE, WIMAX...) and ALL Mobile OS standards (Blackberry, Apple iPhone, Symbian, Google Android, JAVA J2ME, Microsoft Windows mobile and more)." Just don't lose your smartphone.
