System for fault-resistant coding of electronic dove rings for dove sport competition, has specific data file decrypted under application of read program on writing and/or reading apparatus, where read program is complementary to algorithm

摘要

The system has a combined writing apparatus and/or reading apparatus (3) provided with a switching circuit for writing and reading the data belonging to a radio-frequency identification transponder (2). A specific data file is encrypted from an identification number and/or data files under an application of an algorithm for a determined circle of the writing and/or reading apparatus and stored on the transponder. The specific data file is decrypted under the application of the read program on the writing and/or reading apparatus, where the read program is complementary to the algorithm.
