Topic: NTAG vs MIFARE UL
I currently have a Mifare Ultralight Card (64 bytes) and an NTAG (168 bytes) and am using the android app "TagInfo from NXP". I am running on a Galaxy S3. So when I scan a Mifare UltraLight Card, it detects it as a Mifare Card with 64 bytes, even identifying the IC itself(MF0ICU1). When I scan an NTAG, it detects the IC Type as an "NTAG203(F)" and determines it has 168 bytes of memory.
So my question is since the SENS_RES (44 00) and SEL_RES (00) values are the same, how did the TagInfo app differentiate between the tags? Is it because it uses a PN544 and I am using a PN532? Any ideas on how it is telling the difference?
