Dear Sirs, unfortunatelly the downloaded product had no purpose to me. Neither there is a develoded authomatic algorithm for membership management, nor such a access control, not to mention the extremely basic services you can set in a gym – services complicated to an extend to different components that could vary in time of the mont, times to visit and so on.

Honestly I am not disappointed, just will never use yout program, and have deinstalled it in 4 – 5 hours of realising the above.

Please, if possible to be refunded accordingly,

Thank you in advance Ivaylo Yosifov +359-884-200874

I need fingerprint attendance with this please. Do you have it?

Please check our profile. Alerady have.

I am sorry but I did not see anywhere in your profile that you allow fingerprint tracking for gym users. So to reframe my questions: does your system allow a gym to track the attendance and grant access to its users based on fingerprint?

Yes! It is possible to add fingerprint based attendance module with this system. Thank You.

Hi there, You are doing a very nice work. Is it possible to implement fingerprint attendance for members in the system? I saw you have another software with fingerprint attendance

Thank you for your providing your valuable feedback. We will be try to incorporate it to upcoming version. Thank You.
