P.S . sorry for my BADDDDD English :smiley:

Have you tried Googling for Arduino RFID reader?

Yes, I try in google and read many information, but I`m novice and I hava a few qu?stions.
Does it matter what kind of reader I use and what library load?

Yes it matters.

How I know who library to use?
example: for this

?
or this

The first one is if you are using 125KHz EM4100 reader and cards. The second is if you are using 13MHz Mirare cards.
Two totally incompatible systems.

My idea is simple, I want just to open a door, and for that which type RFID reader should I use?

It does not matter what reader you use but what ever it is you must use a library designed for that type of reader.

Check SparkFun. They have a series of RFID reader modules that are Arduino-friendly, with some code examples, and a selection of tokens and access cards. They're all of the 125kHz variety.

I've looked around a little, and while at first I thought their selection was a little spendy, I haven't found a better deal anywhere else. So apparently $25 for a module and $2 per card is a reasonable price. IME, SparkFun's prices are generally competitive, I just thought the cards would be easily found for less in qty 10 or less. Maybe you need to buy in bulk before they start getting cheap.

I hit Send to quickly.

The eBay auction mentions that it is an RDM6300 based reader, so I just did some Googling. Found a thread in this forum from earlier this year, and a few more links:

I hope some of this helps.
