Interesting about android NFC whitelist nfcee_access.xml file

Since the wallet only works if its signature is in this whitelist file, we can deduce the business strategy.
Below is the list of app signatures in whitelist nfcee_access.xml file in different popular android phones:

– Nexus S, Nexus 4: Google wallet (of course).
I guess this is only way I get Google Wallet if you have T-Mobile & AT&T.
– Verizon Note 2: VZW ISIS + VZW CERT.
ISIS Wallet only.
– T-Mobile GS4: ISIS development + production.
ISIS Wallet only.
– International GS3: Google wallet + Samsung wallet.
Samsung has its own wallet too.
– Sprint GS3: Google wallet
– Sprint GS4: Google wallet + Sequent Wallet.
Reflecting Sprint new business deal with Sequent.

Android NFC card emulation events

Android provides various NFC card emulation events in hidden com.android.nfc_extras package.
See below:

com.android.nfc_extras.action.AID_SELECTED
com.android.nfc_extras.action.APDU_RECEIVED
com.android.nfc_extras.action.MIFARE_ACCESS_DETECTED
com.android.nfc_extras.action.RF_FIELD_ON_DETECTED
com.android.nfc_extras.action.RF_FIELD_OFF_DETECTED
com.android.nfc_extras.action.EMV_CARD_REMOVAL

However, I only receive RF_FIELD_ON_DETECTED, RF_FIELD_OFF_DETECTED, AID_SELECTED.

Read credit card using Samsung Galaxy S 3

I have been working NFC controller for awhile.
But I didn’t have it in my personal phone until last week when I upgraded from Galaxy S2 to S3, which has NFC.
I was like a little kid, going around find tags & credit cards to read.
Yes, credit card. “Chip and Pin” credit card to be exact, not US mag stripe credit card (unless you have Chase Blink or Amex card).

I found 2 apps on Google Play enabling me to read “Chip and Pin” credit card. One of them is Electronic Pickpocket RFID.
This app will not help thieves steal. This app only shows part of your account number as a precaution.
(The other one is very technical & hard to read, so I don’t want to mention it here.)

Here is my experience:
– Very close range !!! (< 1 inches). Almost touching the card.
– Need few seconds to read the card.
– Take several tries to get a good read (due to antenna issue of S3 ?)

Given the limitations above, so your credit card is still safe from consumer NFC phone.
