 With his smart card in hand, the farmer enters a market, picks out what he needs and approaches the storekeeper to pay for his goods. The storekeeper hands the farmer a Universal Communicator and he inserts his smart card into the unit. The farmer points his Communicator at the storekeeper's Communicator and transfers the cost of the
goods from the farmer's card to the storekeeper's with a touch of a button. In the middle of the air, a part is sent to the government, another part is sent to the bank of the store keeper
to pay for the goods he just sold, one more is sent to the town treasury again and service charges and communications fees are also deducted.
