Motorola Inc has acquired San Jose, California-based Indala Corp, a manufacturer of radio frequency cards and tags used for vehicle identification and industrial automation. Terms of the agreement were not disclosed. Indala’s tags are encoded with identification numbers that can be recognised by sensors at a distance without physical contact, and are used to permot authorised cars and trucks to drive into a security area without delay, to mark storage pallets, and to sort laundry in places like hospitals and boarding schools. Indala is to join Motorola’s Automotive and Industrial Electronics Group, Northbrook, Illinois.
