PIN

John had been imprisoned for many years to remember what his last wrongdoing was, a thief by profession as he was, he had never had problems with justice, because his technique was silent and he never left any hint that linked him, this time something distracted him, the girl in the red dress who had seen in the elevator, who had left him thinking? who knows. He had never been distracted before, but this time the debts were overwhelming him. Who was going to think that removing the mask slightly to dry the sweat was going to be enough to identify him, and well, there was still a possibility, but when pushing his defense lawyer, he hit his head and became unconscious and then lost his life in the operating room.

Thirty years went slower than he thought, when he left prison he could still lift a lump of cement, but at sixty, who was going to give him work. He spent the first few days searching through the garbage, and then decided to go back to the streets, looked for an ATM and waited for his first victim.

Standing in front of the cashier it was very rare to him not to find a hole for the card and the exit of the money, but that was not going to stop him, a few minutes later a young man arrived who stood in front of the cashier and reloaded in his hand extended right. John approached him and took him by the neck demanding the money, the young man did not resist and immediately handed him what he had in his hand, which turned out to be a package of takeaway food, John took the package and stepped aside , the young man, seeing that he was an old man who looked very tired, decided to help him.

-I can't give you money because that ceased to exist about twenty years ago- the young man told him. He explained that everything is based on the DNA of people, and that he just had to place the palm of one of his hands or any part of the body on the reader and this when detecting that he is alive would it will generate a temporary random PIN based on his emotional state.

-It turns out that when I get scared, you block my resources and I will not have access to them until I am completely calm, but let me help you access yours - the young man told him.

John placed his right hand on the reader as the young man told him, but only a blocked user message appeared, the young man, seeing that he was very anxious asked him to calm down, to eat the food he was carrying and to rest a little bit. John did so, he told him that he had just left prison, so the young man did not flinch, about half an hour later, John tried again, it turned out that he had enough funds to live five years for the wages he I was generating in jail.

-You have to look for a job, because it is illegal not to work even if you have to subsist, but that job, due to your age, can be only four hours a day, until you reaches seventy - said the young man.
