The one thing that will seal your fate to hell before dying is taking the mark of the beast in your hand or forehead.  I think the link below is likely to be similar to the mark of the beast the book of Revelation talks about.  David Wilkerson saw a vision of the future and he said he believes that the mark of the beast will be an invisible tattoo.  Make sure no man's vision or opinion ever takes place of what the word of God says.  The attached link is about a tech tattoo that can hold all of your financial and medical information.  The Antichrist system will make everyone believe that the mark is a great idea with a lot of benefits.  The Bible speaks about how people will not be able to buy anything or sell without this mark (Revelation 13:17).  It also says that if you take this mark you WILL go to hell (Revelation 14: 9-12).  There is no repenting once this mark is on you.  You may not be able to work, buy things or eat but it's better than an eternity in hell.  Anyone who takes this mark will break out in sores all over their body (Revelation 16:2).  I don't know for sure what this mark will be.  Keep your eyes open, pray about it and don't take anything that will be on your hand or forehead even unto death.  http://newyork.cbslocal.com/2016/01/29/tech-tattoos-chaotic-moon/
