Answer:
As you may know, information chips are already encoded in the visas of people who need them for work, travel, or study in this country.
Step-by-step explanation:
The sentence above is correctly punctuated. The comma is used appropriately in the sentence. Commas are used to separate independent clauses especially when there is a conjunction joining them such as but, or, yet, so.
Example: 1) Yesterday was my daughter's birthday, so I took her out to dinner.
2) I left the house early enough, but I still didn't meet up for the meeting.
Commas can also be used after the first clause or phrase in a sentence.
Example: While I was eating, the alarm clock rang.
After the test, we left for home.
Commas are used to separate three or more words. They are used to itemize things in a sentence.
Example ; She bought some oranges, apples and paw-paw for her uncle last week.
