The Transaction Key and Hash Key are part of the security system of SellerDeck Payments. Each Terminal ID (TID) will have an associated Transaction Key and Hash Key. SellerDeck will tell you your Transaction and Hash Keys so that you can enter them into your SellerDeck system. They must be entered exactly as given (ie, they are case sensitive). Even the smallest slip, for instance confusing the letter O (oh) with the number 0 (zero), will mean that SellerDeck Payments will not work.
