"The manual for model "A1844" —which supports both NFC and Bluetooth Low Energy —includes wiring instructions, and in fact says that users have to "present the company provided credential to the reader," Business Insider noted. The system will flash green or red and play a sound to indicate access."
Considering the niche appeal of access products, it is surprising that Apple - one of the world's largest tech companies - would do any R & D on door access. One the other hand- if they intend to go to market with it, they'll need little introduction of who they are to potential customers.
What do you think? Could 'Apple Access' be the next big thing?
