Encoded data transmission method, involves calculating unique code, and comparing unique code with another unique code, which is added to data string such that authenticity of data string is verified
The method involves transmitting data string from a coin verifier to a central control unit, where the central control unit utilizes a same coding algorithm from received coin data, a stored static code and a dynamic code. Another dynamic code is calculated and quickly stored, where the latter dynamic code is an input variable for subsequent encoding. A unique code is calculated and is compared with another unique code, which is added to the data string such that authenticity of the data string is verified.
