GOVHK - Applying HK Smart ID Card

I hope you can help and provide me some information about HK Smart ID Card, I was from HK and living in USA for over 30 yrs., and will be visiting HK end of May. Would like to know if HK Gov't still accept application for this Smart ID? If they do, how to get there from Metropark Hotel at 75 Waterloo Rd., Kowloon (to the HK Gov't Agency to apply)? Thank you.
