| 摘要 |
The present invention relates to a method of bidirectional communication with coded patterns between communication devices, said coded patterns being machine-readable optical codes, such as barcodes. The present invention is defined, in its broadest sense, as a method of bidirectional communication between a first communication device and a second communication device wherein:
- a first code pattern is received by the first communication device,
- retrieving a message from the coded information of said first barcode,
- elaborating a response of the message,
- generating a second coded pattern comprising the elaborated response,
- transmitting the second coded pattern to the second communication device. |
