nrf52832 NFC for payment purpose

[Bosemani_Raja]

Hello everyone,

I have a few questions related to NFC in nrf52832.

1. UUID in nrf52832 NFC is Unique?

2. Can I use nrf52832 NFC for payment purposes..? if yes How I can do?

3. RFID and NFC both are working at the same time or do we need to choose any mode?

(In RFID mode it should transmit the UUID only, In NFC mode the data transfer should occue)

4. for payment method any external encrypting chip is required?

<<Thank you>>

Hello,

1. UUID in nrf52832 NFC is Unique?

I don't know how much you have looked into the NFC examples. They typically set up an NFC packet that is transferred on connection, but I don't think that packet includes any UUID by default. The nRF comes with a unique address, which I guess you can use in the NFC packet if you like.

2. Can I use nrf52832 NFC for payment purposes..? if yes How I can do?

I am not sure. I guess this is a bit outside of our expertise. There is a lot of other things you need access to before being able to handle bank transactions than NFC. I guess you need to get in touch with either a bank, Visa or Ingenico or similar to discuss the needs for that. 

3. RFID and NFC both are working at the same time or do we need to choose any mode?

(In RFID mode it should transmit the UUID only, In NFC mode the data transfer should occue)

I think NFC is a subset of RFID. We usually say that we have NFC, but not RFID, but then again, NFC is RFID.

4. for payment method any external encrypting chip is required?

I am not sure.

I guess this is a bit outside of what we work with. If you want to discuss this with our RSM (Regional Sales Manager) for your area, please send me a PM here on Devzone, and I can give you their contact information. Perhaps they have been in touch with some other customers working on a similar project, and they can give you some directions on where to go to achieve your goal. 

Best regards,

Edvin

Thank you so much edvin .

I went through the datasheet I found out about this register part.

 NFC.TAGHEADER0 ,NFC.TAGHEADER1,  NFC.TAGHEADER2, NFC.TAGHEADER3, these are what ID 's.

I think these belong to NFC.

can you tell me about these Registers? 

[Edvin]

That is correct. This is a uniquely assigned address consisting of 16 bytes. split along those 4 registers. 

You can see how it is used in nrfx_nfct_nfcid1_default_bytes_get() in the nfc examples from the SDK. I see that it only uses 3 of the registers. Perhaps it only needs 12 address bytes. 

Best regards,

Edvin
