Where to find a "acr122u" at the best price?

I am looking for a RFID reader ACR122U kind to start playing with NFC. I found readers for $ 55 with shipping on Ebay.
The price is reasonable?  Does it exist cheaper?
Thank you.

Le prix est raisonnable? Existe-t-il moins cher?
Merci.

Re: Where to find a "acr122u" at the best price?

I wouldn't recommend buying ACR122U(PN531 chip) because of bad emulation support using libnfc. Read a topic about this at libnfc forum. Have a look at scl3711(pn533, ~35 USD) or open-hardware pn532 breakout board(~50USD).
Or you can join to a group buy of proxmark(http://www.proxmark.org/forum/viewtopic.php?id=1607)

Re: Where to find a "acr122u" at the best price?

Thank you for the information. The scl3711 to look good.
Otherwise, the SL500 is Stronglink?
There is no clear subject that describes how to find the key A and B with a type of material? For now I'm confused :'( ...


Merci pour ses informations. Le scl3711 à l'air bien.
Sinon le SL500 de Stronglink est bien?
Il n'existe aucun sujet claire qui explique comment trouver les clé A et B avec un type de matériel? Car là je suis un peu perdu :'( ...

SL500F is manufactured by Stronglink and it is NOT able to crack mifare and there is no way it can be "hacked" to do that.

I'm lost ... I must take the scl3711 if I want to try to decipher my mifare card?
If SL500F is not able to decipher the card mifaire what can it serve me?

Je suis perdu... Il faut que je prenne le scl3711 si je veux essayer de déchiffrer ma carte mifare?
Si le SL500F n'est pas capable de déchiffrer la carte mifaire à quoi peut-il me servir?

SL500F is not for mifare cracking. I don't use scl3711 so I cannot help you with this.

Re: Where to find a "acr122u" at the best price?

Then I am pretty sure the Proxmark 3 will give you the answers you are looking for...
But if "full" cloning is what you want to achieve, you might need to buy a "magic Chinese UID changeable" mifare card. (depending on how many you buy, it can go from 20.0USD to 3.5USD per piece)

Re: Where to find a "acr122u" at the best price?

If I find the key A and B then I could see and edit all the data?
So no need for a new card. My reasoning is good?

What are you looking for ? Cloning your card or just modifying the data of your card ?

I try to find key A and B to be able to modify the data. I do not try to clone.
