RETAIL PLUS POS - Data Security Questionable.

I have been using retail plus for my business for about a year, it is a licensed version.
My business is run by various staff as as I have multiple businessess, therefore, I have to depend on the security of the POS inventory control and sales control before I can depend on any staff, as employees may change from time to time one never knows the realiability of the employee, hence we rely on the security of our POS and Control systems. I recently found a serious flaw in RETAIL PLUS Pos, I have put forward my concerns to Mr.Kuno Egger of www.retailsoftware.com to take corrective steps. If it is not done soon, I will advise all concerned readers on this blog of what the flaw is for you all to take corrective measures.
