Perhaps I should have mentioned the complete set of ayat.
Please view the ayat:
YUSUFALI: They will say to their skins: “Why bear ye witness against us?” They will say: "Allah hath given us speech,- (He) Who giveth speech to everything: He created you for the first time, and unto Him were ye to return.
PICKTHAL: And they say unto their skins: Why testify ye against us? They say: Allah hath given us speech Who giveth speech to all things, and Who created you at the first, and unto Whom ye are returned.
SHAKIR: And they shall say to their skins: Why have you borne witness against us? They shall say: Allah Who makes everything speak has made us speak, and He created you at first, and to Him you shall be brought back.
I then again read Tafsir of the ayat in question which reads as follows:
{ وَقَالُواْ لِجُلُودِهِمْ لِمَ شَهِدتُّمْ عَلَيْنَا قَالُوۤاْ أَنطَقَنَا ٱللَّهُ ٱلَّذِي أَنطَقَ كُلَّ شَيْءٍ وَهُوَ خَلَقَكُمْ أَوَّلَ مَرَّةٍ وَإِلَيْهِ تُرْجَعُونَ](http://javascript:Open_Menu()) }
And they will say to their skins, ‘Why did you bear witness against us?’ They will say, ‘God made us speak, Who gave speech to all things, in other words, [all things] which He wanted to [be able to] speak. And He created you the first time, and to Him you will be returned: it is said that this statement is made by their skins; but it is also said to be God’s words, as is the case with what follows, for it is similar in context to what preceded, namely, that the One with the power to originate you without any precedent and restore you to life after death, also has the power to make your skins and your limbs speak.

To be very frank. At the day of judgement we will not be in our body. We will be in SOULs. The only thing I can think of skins bearing witness against our deeds is in this world. And as far as I can remember with my very limited knowledge that the whole body does not have prints which can match our fingers.
This is something interesting I read online:
A fingerprint is an impression of the friction ridges of all or any part of the finger. A friction ridge is a raised portion of the epidermis on the palm and fingers or sole and toe skin, consisting of one or more connected ridge units of friction ridge skin. These ridges are sometimes known as “dermal ridges” or “dermal papillae”.
…No two fingerprints have ever been found identical in many billions of human and automated computer comparisons…
I guess I dont have to say much on this.
