I am currently trying to decide which phone to get in order to create a prototype/proof of concept application for building access using NFC. The two main phones I have been looking at are the Nokia 6212 and 6131, but if anyone believes that a newer phone model may be better I would really appreciate suggestions!
So I have a couple of questions that I have been unable to confirm the answers of so far:
1) Am I able to set/change the UID when the Nokia 6212 is acting as a Mifare classic? I have read that the 6131 sometimes sets a random UID: http://mulliner.org/nfc/feed/collin_...nfc_phones.pdf but I have no idea about the 6212
2) The 6212 has a dedicated Secure Element (SE), whereas newer phones use the SIM and Single Wire Protocol (SWP). Are there any important advantages/disadvantages for either? I would assume that it is easier to load a custom application onto the 6212 as opposed to a SIM card on other phones? Bear in mind that I am merely making a proof of concept application so it does not need to be transferable between different phone models.
Any help or advice would be greatly appreciated.
