Hii I've read carefully all your requirements and I'm confident enough that I can do it. I previously work with a company where I have to design a RF Employees ID card. The system stores data like when they Entered, who much time the spend in, when they got out, etc etc.. And it's works with a daily load of 1500 employees. Your project also quite similar. So I can easily do it. I'm very excited to get into this project. It would ne great time for both of us. I have some queries which we can sorted in chat. Hope we will have a talk, and the matter of fact is I love beer!
