magnetic stripe reader

Hi is there a way to read a magnetic stripe reader with arduino ??

(deleted)

Yes, plug it in, power it, write code, done.

how ?? how can i read the data ? is there a way to read it from i2c spi ??? how

I think it depends on the card reader you have.

I just googled "magnetic stripe reader arduino" and found quite a few promising-looking hits.

Yes, plug it in, power it, write code, done.

Don't forget to wire the two together, properly!

Again, that would depend on the type of card reader.

i want to snif the packet from the magnetic stripe reader is it possible ?

Depends on the card reader. Many don't send a packet.

This type of card ISO Magnetic Stripe Card Standards | Q-Card
i want to read the 3 tracks

Do you have a card reader?

the card reader is pluged on android i9000s, it like a extension that we plug on android i9000s

Provide a link to the reader that you have.
We need more information.

For what purpose?

The MSR (magnetic strip reader) http://www.yuebao.com/en/product_detail.php?id=23, i want if there is a way to read information from this MSR via arduino ??

The link provides no technical information.
It may be possible to hack it but will require both skill and fairly sophisticated tools.
It looks like a part to be used in an OEM device.
Do you really actually poses one .?

Also coding badly comment , why ?

That is not a reader. It is a reader head.

What is the diferance between a reader and the head reader ??

Last chance. Answer my question.

A small PCB with electronics.

Last chance. Answer my question.

the system that has this Magnetic stripe reader can't detect the data of a magnetic card, so i want to know if there is a way to read the card with arduino to see if the problem is due to the android or the magnetic card

What is "the system"?
