FIELD: radio engineering, communication.
SUBSTANCE: transmitting method through the information processing device, such as the chip card, the message, using at least one hidden physical communication channel, in the form of the detectible and controlled change of the mentioned device hardware characteristic, contains the following stages: transmit the preamble, consisting of variable characters sequence, encoding the binary values '0' and '1' after which goes the delimiter character; transmit the significant part, forming the contents of the mentioned messages and consisting of the characters '0' and '1' sequence, optionally separated by the delimiter character '2'. The method also includes the sequence beginning mark preliminary assignment stage in the form of the character other than the characters, that are used to encode the message and/or the following sequence end mark preliminary assignment stage in the form of the character other than the characters that are used to encode the message.
EFFECT: increase of the data transmission rate.
