Yes but if we are to draw our doctrine from Scripture and what God inspired to write, then it is a physical mark. We already d this with pets and packages. I think it is Norway or Denmark where some companies have injected a small chip into peoples hands for their employment. They have to swipe their hand to get in, use the elevator, vending machines, access their computers etc.
God does not need a physical mark for He can see tehe heart, but Stan cannot so He needs a physical mark to identofy those who are HIs.
I don't deny the technology of chips implanted beneath human flesh already exist. What I do not believe is that the mark of Satan is a physical mark. I believe Satan in his desire to mimic Christ would mark his followers in like manner Christ seals His saints. Since Satan is said to come as an angel of light and his ministers as ministers of righteousness, it doesn't make sense for him to physically mark his followers. That would after all destroy his deception.
2 Corinthians 11:14-15 (KJV) And no marvel; for Satan himself is transformed into an angel of light. Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works.
