1. A system for securely storing a digital coin where the value of the digital coin is based on the count of its bits and where payment with the digital coin is provided by emitting bits from the system one bit at a time, comprising:
- a secure enclosure, fitted with a payment port that emits bits from the digital coin;
a memory contained within the secure enclosure that stores the digital coin;
payment control circuitry (PCS) contained within the secure enclosure that controls payment from the digital coin by removing one or more bits from the digital coin in the memory and emitting the one or more bits through the payment port one bit at a time; and
a tamper-resistant apparatus contained within the secure enclosure that resists attempts to compromise the secure enclosure by including within the secure enclosure one or more ofa light detection system that erases the digital coin from the memory upon sensing light in the otherwise dark internal of the secure enclosure,a pressure detection system that erases the digital coin from the memory upon sensing a change of the pressure in the internal volume of the secure enclosure, andan absorption detection system that erases the digital coin from the memory upon detecting with a radiation detector a change in the absorption of radiation emitted by a radiation emitter above a threshold level, wherein a change in the absorption of radiation emitted by the radiation emitter is a result of a change in the gaseous composition of the space between the radiation emitter and the radiation detector.

Abstract
This invention describes a set of related procedures designed to co-operate with mints of digital money in order to allow for said money to be properly, securely, and conveniently traded by, various size and various type of trading crowds. The procedures refer mainly to distribution of responsibility. This invention also specifies the construction of digital coins encapsulated in a physical housing to amount to off-line tradable digital coins.
