Saw this question asked recently, "Is it really proper that he (the shinshoku) should be wearing electronics/modern luxury (a gold wristwatch) during ooharae?" There are a number of reasons why this is acceptable and proper behavior.

shintô is mainly concerned with living well in this world. That includes taking advantage of modern conviences, and those acting as priests are not required to forego those conviences.

Of course our behavior is subject to kannagara-no-michi (the way in accordance with the will of the kami), but if the kami don't object, who are we to do so?

If kami are a part of everything, then that wristwatch also has kami as part of it. As such it basically starts out pure, and unless it comes into contact with kegare, there is no reason to exclude it.

Of course you don't want your cellphone ringing in the middle of a ritual, but that's what the off button is for. So as long as it's not intrusive, having technology on your person is acceptable.

While shintô is by its nature tradition oriented, it is not static and unchanging. It's constantly re-inventing itself as it adapts to new challenges.

This is especially true when it comes to technology. Now days you can get your car, boat, house, or computer purified and blessed. Shrines even sell omamori to protect your car, cellphone, or computer. Many shrines have their own websites and belong to various social media sites; many shintô priests are perfectly comfortable using a computer.

Here in the Twin Cities area both local shrines are run by people who make their living with computer-based technologies.
