We can infer from Apocalypse of St. John 19:20 that not everyone will have the character ("mark") of the beast on their foreheads or right hands, or not everyone (if everyone is still forced to have it) who has the character will adore the image of the beast. The elect in Christ will either avoid taking on their person (forehead or right hand) the character, or if they're still forced to have it, they won't adore the beast's image.
And the beast was taken, and with him the false prophet, who wrought signs before him, wherewith he seduced them who received the character of the beast, and who adored his image. These two were cast alive into the pool of fire, burning with brimstone. ~ Apocalypse of St. John 19:20
