In the semifinals of women's individual épée, she lost to German Britta Heidemann after a timekeeping error extended bout time.

Without the extension, Shin would have won the tied bout on the basis of priority, which is randomly awarded to one fencer prior to the overtime period.

[4] The result was partly due to the failure of the referee to stop both fencers restarting closer than the specified distance, Heidemann's "crowding" to hurry her attack, and Shin trying to avoid retreating across her end line.

[5] The South Koreans immediately appealed the decision, stating that 0.02s had already elapsed and the final touch occurred after the end of the bout.

An hour later, Shin returned for the bronze medal match but lost to her Chinese opponent despite loud encouragement from the cheering crowd.
