Contactless punching using SIAC cards is relatively new in North America. GAOC has been using contactless punching at local meets for a couple of years and it has been well received by competitors.

We will be offering mixed punching in the non-interscholastic classes this year. Competitors can use traditional contact epunches, or contactless SIAC epunches as they wish. The controls will be programmed in beacon mode which will allow operation with either epunch. Only traditional contact epunches will be allowed in the interscholastic classes.

Traditional contact epunches leave a record on the control when it is punched. This can be useful when there is a protest. Be aware that contactless SIAC epunches leave NO record on the control.
