Using bar-codes in an asset storage and transfer system
View Patent ↗A secure asset storage and transfer system. A first display displays a first bar code encoding a request message including an asset value amount to be transferred. A first camera-equipped device is configured for: reading the first bar code, decoding the first bar code to recover the request message; generating a value transfer message for transferring asset value amount to be transferred from a storage medium associated with the camera-equipped device; encoding the value transfer message to generate a corresponding second bar code; and displaying the second bar code on a second display. A second camera-equipped device is configured for reading the second bar code, and decoding the second bar code to recover the value transfer message.
1. In a secure asset storage and transfer system comprising a first and second storage media configured to securely store and transfer asset value, a method of enabling secure exchange of asset value from the first storage medium to the second storage medium, the method comprising:
a first device operating to:
cause the first storage medium to generate a value transfer message for transferring a selected asset value amount from the first storage medium to the second storage medium;
encode the value transfer message using a barcode encoding scheme to generate a corresponding bar code; and
display the bar code on a display of the first device;
a second device operating to:
read the bar code from the display of the first device;
decode the read bar code to recover the value transfer message; and
cause the second storage medium to process the recovered value transfer message to receive the selected asset value amount.
2. The method of claim 1 , wherein the bar code is a Quick Response (QR) bar code.
3. The method of claim 1 , further comprising steps of:
generating a request message including an asset value amount to be transferred;
encoding the request message using a barcode encoding scheme to generate a corresponding request bar code;
displaying the request bar code such that the bar code can be read by a camera-equipped device.
4. The method of claim 3 , wherein the step of displaying the request bar code comprises displaying the request bar code on an electronic display screen.
5. The method of claim 3 , wherein the step of displaying the request bar code comprises displaying the request bar code on a static display.
6. A system comprising:
a first display displaying a first bar code encoding a request message including an asset value amount to be transferred;
a first camera-equipped device configured to:
read the first bar code,
decode the first bar code to recover the request message;
cause a first storage medium to generate a value transfer message for transferring the asset value amount to be transferred from the first storage medium to a second storage medium;
encode the value transfer message to generate a corresponding second bar code; and
display the second bar code on a second display; and
a second camera-equipped device configured to:
read the second bar code;
decode the second bar code to recover the value transfer message; and
cause the second storage medium to process the recovered value transfer message to receive the selected asset value amount.
7. The system of claim 6 , wherein the first bar code is a Quick Response (QR) bar code.
8. The system of claim 6 , wherein the first display is any one or more of a static display and an electronic display screen.
9. The system of claim 6 , wherein the second camera-equipped device includes the first display.
10. The system of claim 6 , wherein the first display is remote from the second camera-equipped device.
11. The system of claim 6 , wherein the first camera-equipped device is a mobile device.
12. The system of claim 6 , wherein the second camera-equipped device is a mobile device.
13. The system of claim 6 , wherein the second camera-equipped device is a point of sale terminal.
