Collection of value from stored value systems
First Claim
1. A method for determining value in a stored value transaction system having a plurality of value storing transfer devices, including a local device, a collection device, a consolidation device and a settlement device, said value transfer devices each having a device identification number, comprising the steps of:
- (1) receiving, by a first transfer device, a first transaction signal from a second transfer device and providing a first certification signal in response to said first transaction signal;
(2) receiving, by said second transfer device said first certification signal and encrypting said first certification signal to provide a first encrypted signal;
(3) receiving, by said first transfer device, said first encrypted signal;
(4) encrypting, by said first transfer device, said first certification signal to provide a second encrypted signal;
(5) first verifying a transaction in accordance with said first and second encrypted signals and transferring stored value between said first and second transfer devices in accordance with said first verifying;
(6) receiving, by a third transfer device separate from said first and second transfer devices, a second transaction signal from a first selected one of said first and second transfer devices and providing a second certification signal in response to said second transaction signal;
(7) receiving, by said first selected transfer device, said second certification signal and encrypting said second certification signal to provide a third encrypted signal;
(8) receiving, by said third transfer device, said third encrypted signal;
(9) encrypting, by said third transfer device, said second certification signal to produce a fourth encrypted signal;
(10) second verifying a transaction in accordance with said third and fourth encrypted signals and transferring stored value between said first selected transfer device and said third transfer device in accordance with said second verifying.

Abstract
A first transfer device receives a first transaction signal from a second transfer device and provides a first certification signal. The second transfer device receives the first certification signal and encrypts it to provide a first encrypted signal. The first transfer device receives the first encrypted signal and encrypts the first certification signal to provide a second encrypted signal. A transaction is verified in accordance with the first and second encrypted signals and stored value is transferred between the first and second transfer devices in accordance with the verifying. A third transfer device, separate from the first and second transfer devices, receives a second transfer signal from a selected one of the first and second transfer devices and provides a second certification signal. The selected transfer device receives the second certification signal and encrypts it to provide a third encrypted signal. The third transfer device receives the third encrypted signal and encrypts the second certification signal to produce a fourth encrypted signal. A transaction is verified in accordance with the third and fourth encrypted signals and stored value is transferred between the first selected transfer device and the third transfer device in accordance with the second verifying.
