All about NFC on Inew V3 (info and tests)

[GeekGirl]

Hi i have tested some days ago NFC with the Inew V3
so now i'm sharing the results and info with you

first of all if NFC and/or GPS is not working dont start to pull out any contacts
as they will easily break.. better is to try this first the following


It seems that the populair and widely available Mifare Classic Cards are currently not supported by Inew V3 but thats not really the fault of this phone or design but it's all about licenses/agreements/costs etc, also some (expensive) brand phones and Tablets like Samsung Galaxy and Nexus have the same issue with these cards, the reason is just because of the hardware chip that is used here (non NXP Brand chip), the Inew V3 does read the UID header (card identification type and serial) without any problems but doesnt read or write any other data, the chip just doesnt include any hardware support to read out the sectors of this card and i doubt that this can be solved with software so its a bit pitty because these cards would be very nice to use to read/write since they have 1kbyte of storage but fortunatly the Mifare Ultralight/NTag203 is working fine
it means that this phone hase a full working NFC chip except built in support for the cheaper Mifare Classic cards



Mifare Classic (not supported) Detect OK R/W Error
Mifare Ultralight C (aka NTAG203) (Supported) Detect OK R/W Succesful!
Topaz 512 Supported) Detect OK R/W Succesful!



Mifare Ultralight C (Size 192bytes, Usable 137bytes) *
NTag203 (Size 168bytes, usable 137 bytes) *
Topaz 512 (Size 512bytes, usable 456 bytes) *
Mifare Classic 1K (Size 1Kbyte, usable 716 bytes) -

* are tested & working fine with Inew V3 in read and write mode as well as most other brands
- not compatible with Inew v3, Nexus and Samsung Galaxy 4 and some other brands and models

also the same NFC problems like detect/initialization might be an issue between phones & tablets with original
NXP brand chips, and phones with another brand/type of chip, if they use same or similair chip then it just works,

Have fun
