Hi I have a sm-a528b/ds
I wanted to know which nfc chip this model mounts and if the smartphone can be used as an nfc reader for the pc

Sorry if this is a faq, but searches don't turn up anything.
I now have a Sony Ericsson K750i as well as an XDA IIs. I carry most of my MP3 music for the XDA on SD cards, but it would be nice to transfer a selection to the Memory Stick Pro Duo card in the K750i while on the road.
Is there an adapter I can use for this, which would be simplest, or (thoughts) both have infa red and both have bluetooth ... but how do I make it work. Thanks.
23 in 1 card reader
Paid £15 incl delivery from Far East on Ebay for a 23 in 1 card reader. It takes CF MD SD MMC SM MS & Memory Stick Pro. Also is a one to three port USB hub.
Just remembered £15 was for 2 units not 1.
Thanks. But I have a card reader. The problem is I need a PC to transfer the files from one card to another, don't I? But I want to do it on the road. Meanwhile have managed to make transfer using Bluetooth on the two phones. Not fast, but it works. Thanks and cheers. A
I've upgraded to Bepe full cube and it's great but I just got a new 8 gb sdhc card which works well in the phone but not in the old sd adapter, i'm trying to load up near 2gb of maps over active sync which keeps dropping the connection ( did this before flashing ) , I thought I would try bluetooth ftp instead but it is no longer supported ?? any ideas
I'm using win Xp
I have just installed an 8 gb sdhc card.
It came with a usb adaptor, which works. It does not work with my old sd card adaptor
They didn't send the usb adapter with mine , plus it's a pain to have to remove it each time
What make is the card and where did you buy it?

Sandisk & Ebay, but like I said that's not the issue here I know I can get that sorted out
I was asking, as I recently bought an 8GB MicroSDHC card from eBay myself, but mine came with a small SanDisk USB adapter, which states on it 'MicroSDHC'.
I get the impression that the card requires a reader that supports SD2.0/SDHC for it to successfully read/write it.
I might be wrong
You are right, it makes sense that the old adapter won't work with the new model card, as for the ftp that's an issue with the rom similar to the mms problems people have been having
Is it possible for the s4 to read a rfid chip using its NFC technology, I just want the phone to register that a chip has been scanned i have been trying but with no success(using various NFC apps, turning NFC on holding chip to phone, nothing happens), Can anyone give me some advice if this is possible and if so what apps they used. thanks.
**Info i found elsewhere online:
"RFID chips operate at several different frequencies whereas NFC tags all operate at 13.56MHz. There is a type of RFID chip that also works at this frequency but I still don't think it will work with an NFC reader"
Can any one verify if the above is correct

NXP-based NFC controllers can read 13.56 MHz RFIDs that are MIFARE compliant and compliant with a few other standards such as NFC and ISO 14443.
Other NFC controllers can read NFC and ISO 14443 tags, but not MIFARE RFIDs. Many RFID cards (such as some products from HID Global) are 14443 compliant but not all.
I can read (to a limited degree due to security features) an access card that is used along with one of HID's access systems using NXP's TagInfo app.

My rfid chips are 125khz frequncy, so im correcting in saying nfc on a 4 can not read that frequency
Hi i am trying to use build a reader app, do you know if the Samsung galaxy S4(ATT) with the new BroadCom chip (instead of NXP chip) can read 14443 Type B tag? If it is, could you suggest any App could show the reading result?
Thanks!

hey, I'm not sure about the type b tag, but broadcom had a quarrel with nxp/didn't pay for the licenses, so some cards from nxp are not supported by broadcom--->nothing you can do
Hello there,
I used a lot my NFC chip on my samsung galaxy S3 to write mifare classic tags. The S3 is equipped with a NFC device from the NXP manufacturer, and is mifare classic compatible. On the Galaxy S4, and following models samsung puts a crappy Bradcom NFC chip which can't write mifare. I'm done with Samsung, and look for a new phone. I like the OnePlus 3, but I can't find detailed specs and the most important; the NFC chip they included : NXP or Broadcom ?
Does anyone knows ? Anyone here wrote on mifare classic tags 1k ?
Thanks !
I haven't gotten my OP3 yet but I assume it should be a NFC chip from NXP - which would mean it should support Mifare 1k cards. (there are a few OP3 teardowns online which reveal multiple different NXP chips for audio and other stuff inside - none mentions the specific NFC chip, but i guess they would not use Broadcom for the NFC chip and use NXP for everything else)
Thanks for your answer, your reasoning seems logic, but you never know for sure OnePlus wouldn't choose Broadcom NFC over NXP chips if they made a better offer than NXP ... Has anyone here tested reading and writing on mifare classic 1k tags with the OP3 ?
It looks like it isn't "crappy Broadcom" that is the problem but "NXP created the Mifare Classic 1K Chip specifically to be compatible with it's hardware and not necessarily to adhere to the protocols" http://www.andytags.com/nfc-tags-compatibility-issues.html#.WAC3KugrLzc. Chips and the "standard" achieved are at http://nfc-forum.org/our-work/compliance/certification-program/certification-register/
Alrigh then, does the OP3 can write on NXP's mifare classic 1k ?
Well, I guess I'll try and find out for myseflf then...
I finally got my OP3 and I can confirm that it can read and write to Mifare Classic 1k cards.
I have issues writing to sector 0/UID - but i think this is because I have the wrong Chinese cards and not an issue of the phone.
I got mine as well and can confirm writing on mifare 1k works. But, it is difficult to find a position which keeps a stable connexion between the phone and the chip. The nfc keeps connecting and disconnecting very quickly, even when I remove the flip cover and keep the chip touching the phone right on the photo lens. It keeps beebing, but sometimes it last long enought to complete the writing. Anyone else has this kind of issue ?
Does work
Well, a little late for this one but can confirm writing to MIFARE classic / ultralight works fine to block 0 too.
Even the card emulator app works fine - with root you can set the uid of the phone instead of having a random one so for access systems that pickup phones and only relie on the UID it's perfect.
No problems with detecting tho
