For gaming, gambling, and lottery systems, and for cryptographic processors in server systems, pseudo-random number generators (PRNG) need to be seeded with truly random data, and it is usually considered important that this random data is made of fair bits with good statistical properties. The invention uses a special set of dice to be handled according to rules for 1) dice shuffling, 2) putting dice to rest in a conventional position, and 3) sensing the discrete outcome. The required system logic is disclosed so that the overall process of random outcome generation, sensing, and conversion into internal random data can be supported by the digital systems that need it. The bar code technology is applied in a novel arrangement such that the whole process is efficient and secure.
