Everything, or most things we do everyday is printed ie food, electric, gas etc. Even our dogs can be chipped (though i haven't had mine done).
I agree chip has definiately something to do with security and keeping children safe.
We know our Lord will keep our families safe, but others don't, who don't know Jesus.
Jesus said: Not even a sparrow, worth half a penny, can fall to the ground without your Father knowing it. And the very hairs on your head are all numbered. So don't be afraid. Matthew10: 20-31
Keep the faith
