The ones in hotels and motels do. They are basically the same magnetic stripe card as a credit or debit card.

What force operates when you use a bar magnet to pick up a paper clip?
Magnetic Force
How is magnetic force defined?
Magnetic Forcenounattraction for iron; associated with electric currents as well as magnets; characterized by fields of force [syn: magnetism]
What will happen if they use hammer to hit the magnet with the strongest magnetic force severaltimes?
the magnet gets weaker
How do you force like magnetic poles together?
You push them together. They won't stay together, though, since the repulsive force will continue acting. OR, use a nutural \ sympathetic strata ... a simple example is use a metal that attracts the magnetic poles ... and they will unite! N --> |Metal| <-- N
How can you test if a magnetic or non-magnetic materials are better at allowing the magnetic force to pass through?
You can use a device that detects magnetism. A compass needle may suffice.
What force does the end of magnets use?
Magnetic Force (obvious):)
Does an electromagnet use an electric force or a magnetic force?
it uses electric force
How do you use the word magnetic force in a sentence?
The magnetic force of the Earth's gravity holds the Moon in it's orbit.
How do you use a key card?
A key card - is a security device. It's normally used to restrict who can access certain parts of buildings, or computers. It consists of a plastic card about the size of a credit-card, which has data embeded on a chip or magnetic strip. The card is either inserted into or swiped across a card-reader - if it's valid, access is granted. Key cards areusually combined with passwords - in case the card is lost or stolen.
The use of a magnetic stripe reader?
The data stored on a credit or debit card is stored not only in the metallic chip - but also on a magnetic strip on the rear of the card. Magnetic card readers read the data from the strip on the card, instead of the embedded chip.
Can a electric current runnng along a wire be used to produce a magnetic force?
Whether or not you use it, there's always a magnetic field surrounding an electric current.When anything that can respond to a magnetic force is brought close enough to the current,it does feel a magnetic force.
What force operates when you use a bar magnet to pick up a paper clip?
Magnetic Force
What is a combination of electricity and magnets?
It is the electromagnetic force that speaks to the electric and magnetic forces. They (electric force and magnetic force) are one force in the eyes of the physicist. Use the link below for more information.
Can magnetic force of repulsion act from a distance?
Yes. That's how the navigator of an airplane in flight is able to use a magnetic compass.
What kind of force do you use to move a trolley?
You can move a trolley with a magnetic force (e.g. use magnets to draw the trolley away from it's original position - assuming it is made of a magnetic material), a gravitional force (e.g. rolling the trolley down a ramp) or with an applied force (e.g. pushing the trolley).
How is magnetic force defined?

Where do you use the Key Card on Counterfeit Island?
You get the Key Card after the scooter chase. You cannot use it until much later. Return to the museum to receive a package. In the Black Widow's lair, the guards are patrolling, but you can reach the locked door to her treasure vault (use the key card to open it).
