i'm trying to understand which entitlements i need to ask for in order to be able to read the credit card via NFC.

I work for the bank and i'd like the read our card in order to verify there are the bank's credit card. The goal is to be able to use the card as a physical token to verify the user identity.

on android we manage to do this without limitation


			if (await NfcManager.isSupported()) {
				await NfcManager.requestTechnology(NfcTech.IsoDep)
				const tag = await NfcManager.getTag()

				if (tag) toast.success("NFC Tag read successfully", { cancel: undefined, description: tag.id, id })
				else toast.error("No NFC Tag found", { cancel: undefined, id })

				 const ppse = await NfcManager.isoDepHandler.transceive([
				 	0x00, 0xa4, 0x04, 0x00, 0x0e, 0x32, 0x50, 0x41, 0x59, 0x2e, 0x53, 0x59, 0x53, 0x2e, 0x44, 0x44, 0x46, 0x30,
				 	0x31, 0x00,
				 ])
				 logger.info("PPSE", ppse.map((c) => fromBase10ToHex(c, 2)).join(" "))

				 const select = await NfcManager.isoDepHandler.transceive([
				 	0x00, 0xa4, 0x04, 0x00, 0x07, 0xa0, 0x00, 0x00, 0x00, 0x04, 0x10, 0x10, 0x00,
				 ])
				 logger.info("Select AID", select.map((c) => fromBase10ToHex(c, 2)).join(" "))

				 const gpo = await NfcManager.isoDepHandler.transceive([0x80, 0xa8, 0x00, 0x00, 0x02, 0x83, 0x00, 0x00])
				 logger.info("GPO", gpo.map((c) => fromBase10ToHex(c, 2)).join(" "))

				 const record = await NfcManager.isoDepHandler.transceive([0x00, 0xb2, 0x01, 0x14, 0x00])
				 logger.info("record: ", record.map((c) => fromBase10ToHex(c, 2)).join(" "))

				logger.info("PAN", findTag(record, [0x5a]))
			 logger.info("expiry", findTag(record, [0x5f, 0x24])?.reverse())
			}

but on ios we have restricted access and the ppse doesn't work but i can't find which entitlement i need to ask for, since HCE is to make the iphone into a nfc tag himself and the tap to pay is to pay with the iphone, both of those doesn't match my needs and i wouldn't be able to valid the requirement to get them into production.

So i am wondering which entitlement i needs to ask for in order to be able to scan the card inside the bank app. We only care about our card

To be able to interact with payment cards, you will need to enroll in the NFC & SE Platform. You can find the eligibility requirements and the steps to take to enroll at the link.

You would use the CredentialSession API instead of the regular ReaderSession APIs in CoreNFC.

Starting a CredentialSession will allow yo auto interact with payment cards.

Implementing the communication between your app and the card is your responsibility. The protocols of processing the payments will differ from card to card.

If you are an authorized developer with a licensing agreement with the credit card supplier, you can get the information on how to implement the protocol directly from them.

Implementing the required protocol is domain specific knowledge that we do not support. Once you have implemented the proper protocol, if you have specific questions about the CredentialSession or general CoreNFC APIs, we would gladly assist.
