RFID

I would not get to hung up on RFID because in its current state it cannot survive a strong magnetic field, like a large speaker, and definitely would not survive being any where close to a MRI machine. (would the man of sin suddenly tell 100% of the populous that they could no longer get an MRI.) Besides it is not necessary for a cashless system and positive (real) ID. The new heath care bill in concert with a super computer being built for the government for health care and the stimulus money for an online health record system would be all that you would need for the infrastructure for the Mark system to work.

Think about the information contained in your medical records. All you would really need to make the system work is a 10 digit code to access the info online for whatever reason. Weather it be for a purchase or ID or medical related that one system could be used . Think about info that has been gathered this year and last. They have done a GPS census on every home in the US and are doing a regular census right now. If you ad that info to the medical records and banking info how easy would in be to construct the mark system.

(On a side note, I had vision last March or April that a health care bill would pass and that it would be used later by the anti-Christ as part of the infrastructure for the mark system. On another side note, I was sitting at my computer last year when I felt the presence of evil. I got up from the computer and looked outside and there was a woman walking up the driveway. The Lord told me that she was doing a GPS survey of the house. I went to the door and opened it before she got there and told her what she was doing there. She was taken aback and just handed me a form and finished what she was doing and hurried away. The Lord told me that that the information would be used for evil purposes in the future.)

I suggest that the false Christ will campaign on the mark system as a way to save every one.
A universal monetary as a way to deal with defaulting massive debt. A new money use tax to replace all of the other taxes to eliminate tax fraud and a way to raise money for services and stimulate the economy. How small a tax would you need if every single purchase where taxed? How much fat could be eliminated from the government if there were no IRS. How much revenue would be gained by the elimination of fraud.

Crime would all but be eliminated. With all purchases recorded, how would you, buy drugs, sell stolen merchandise, or evade the law? If you were wanted by the law for questioning they could just turn off your account, and you would have to turn yourself in or starve. How would terrorists operate? There would not be any such thing as a fake ID and you would not be able to travel without the mark.

The pseudo-Christ will chide and mock those that would be against the mark. Christians will be blamed for holding up economic relief.

I don't know what kind of tech they will use for the mark. But don't get so hung up on one system that you don't see the other sneaking around the corner.
