where does the bible said about rfid chip?

Perhaps here........

11 "Then I (John) saw another beast rising out of the earth. It had two horns like a lamb and it spoke like a dragon. 12 It exercises all the authority of the first beast in its presence, and makes the earth and its inhabitants worship the first beast, whose mortal wound was healed. 13 It performs great signs, even making fire come down from heaven to earth in front of people, 14and by the signs that it is allowed to work in the presence of the beast it deceives those who dwell on earth, telling them to make an image for the beast that was wounded by the sword and yet lived. 15And it was allowed to give breath to the image of the beast, so that the image of the beast might even speak and might cause those who would not worship the image of the beast to be slain. 16Also it causes all, both small and great, both rich and poor, both free and slave, to be marked on the right hand or the forehead, 17so that no one can buy or sell unless he has the mark, that is, the name of the beast or the number of its name. 18 This calls for wisdom: let the one who has understanding calculate the number of the beast, for it is the number of a man, and his number is 666.

Revelation 13:11-18 ESV

some surmise the mark may be something like the rfid chip

Nowhere.

It does not. There is the mark of the wild beast 666. (Rev. 13:16-18) This has nothing to do with any micro chip. Numbers in the Bible, have meanings. "666" stands for "6" imperfection and three times denote emphasis. So the number highlights how truly imperfect it is as part of belonging to that beast or being a supporter of it. Wild beasts, as seen from Daniel, Isaiah and Ezekiel are symbolic of human political world powers.

So the "mark of the wild beast" would symbolize identifying those supporters of the world's human governments in opposition to God's Kingdom heavenly government.

"And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name. Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six. (Revelation 13:16-18, KJV)" this happens In the tribulation

Call it what you want but I read a secular article not long ago that said the best places to put the chip were in your right hand and forhead!

Possibly.

Where does the Bible talk about Radio Frequency Identification Chips?

You're sh!tting me right. xDDDD

it does not mention the rfid chip

I guess itt is implied in the section about the mark of the beast.

all shall mark

Nothing about a chip, only speaks of a mark given to those that choose to worship the beast.
