Budget-conscious companies will love the new Sudokia PZL, which will not work until the user solves the puzzle that also serves as the keypad.
“We’ll save a bundle on minutes,” said Frank Zolini, IT manager for Frontage Road Sales. “You really have to think about what you’re going to say, and get it done quickly before it scrambles again. It might make some of us smarter, who knows?”
The phone operates for three minutes each time the puzzle is solved, then reshuffles.
