Shop has no webcamera for capturing photograph to make identy card from customers. Instance observed that staffs capture photograph by using their own cellphone.
What about this sentence?.
OK, thank you for correcting those errors. Now let's deal with the content.
I assume you are talking about a specific shop, so you need to add an article before the word "shop".
We rarely say "web camera" - it's usually "webcam".
We say "taking photographs" rather than "capturing".
The shop doesn't just take one photograph so the singular is inappropriate.
The shop doesn't just make one identity card so the singular is inappropriate.
We don't make things "from" customers. That means that we change customers into something else, or use customers as an ingredient. Try to find another preposition.
I don't know what you are trying to say by "Instance observed". Can you try to use different words to explain what you want to say?
Check a dictionary for the word "staffs". It exists in the plural but only when using the countable definition of "staff". You are looking for the uncountable form.
The same advice for "capture" and "photograph" applies in paragraph 2.
Following that advice, make some changes to your sentence again.
