# NFCPaymentTagReaderSession A reader session that supports the use of payment tags. ``` class NFCPaymentTagReaderSession ``` ## Overview This subclass of [`NFCTagReaderSession`](/documentation/CoreNFC/NFCTagReaderSession) adds support for payment tags, when someone uses your app in certain regions. To support payment tags in your app, intialize this class with a [`NFCTagReaderSessionDelegate`](/documentation/CoreNFC/NFCTagReaderSessionDelegate-2joku). The delegate receives an object that conforms to the [`NFCISO7816Tag`](/documentation/CoreNFC/NFCISO7816Tag) protocol when the [`NFCTagReaderSession`](/documentation/CoreNFC/NFCTagReaderSession) detects an ISO 7816-compatible tag. For the delegate to receive the tag object, your app must include: - The - A list of supported application identifiers in the information property list key When the session discovers an ISO 7816-compatible tag, the session performs a `SELECT` command for each application identifier provided in . The `SELECT` command searches for the identifiers in the order in which they appear in the array. The session calls the [`tagReaderSession:didDetectTags:`](/documentation/CoreNFC/NFCTagReaderSessionDelegate-5gxiw/tagReaderSession:didDetectTags:) delegate method after the first successful `SELECT` command. The [`initialSelectedAID`](/documentation/CoreNFC/NFCISO7816Tag/initialSelectedAID) property of the found tag contains the selected identifier. The tag must be available to the reader session, so it can read and write data to the tag. Use the [`isAvailable`](/documentation/CoreNFC/NFCTag-swift.enum/isAvailable) property to check the tag’s availability. To connect to an available tag, call the superclass’s [`connect(to:completionHandler:)`](/documentation/CoreNFC/NFCTagReaderSession/connect(to:completionHandler:)) method. The system only supports one active [`NFCReaderSession`](/documentation/CoreNFC/NFCReaderSession-swift.class) at a time. The system queues and processes subsequently opened sessions in first-in-first-out order. > Important: The system supports use of `NFCPaymentTagReaderSession` only within the European Union (EU). To develop and test an app that uses this feature, see [Request the NFCTagReaderSession Development Entitlement](https://developer.apple.com/contact/request/nfc-payment-tag-reader/). People using your app must have an account registered in the EU, and their device must be located within the EU. If the device isn’t currently eligible to use `NFCPaymentTagReaderSession`, the `NFCPaymentTagReaderSession.readingAvailable` property is `false`. ## Topics ### Creating a tag reader session [`convenience init(delegate: any NFCTagReaderSessionDelegate, queue: DispatchQueue?)`](/documentation/CoreNFC/NFCPaymentTagReaderSession/init(delegate:queue:)) Creates a new session instance for processing NFC payment tags. [`protocol NFCTagReaderSessionDelegate`](/documentation/CoreNFC/NFCTagReaderSessionDelegate-2joku) A protocol that an object implements to receive callbacks sent from an NFC tag reader session. [`- (instancetype) initWithDelegate:(id) delegate queue:(dispatch_queue_t) queue;`](/documentation/CoreNFC/NFCPaymentTagReaderSession/initWithDelegate:queue:) Creates a new session instance for processing NFC payment tags. [`@protocol NFCTagReaderSessionDelegate `](/documentation/CoreNFC/NFCTagReaderSessionDelegate-5gxiw) A protocol that an object implements to receive callbacks sent from an NFC tag reader session. ## Relationships ### Conforms To [`NSObjectProtocol`](/documentation/ObjectiveC/NSObjectProtocol) [`Equatable`](/documentation/Swift/Equatable) [`CustomStringConvertible`](/documentation/Swift/CustomStringConvertible) [`CVarArg`](/documentation/Swift/CVarArg) [`CustomDebugStringConvertible`](/documentation/Swift/CustomDebugStringConvertible) [`NFCReaderSessionProtocol`](/documentation/CoreNFC/NFCReaderSessionProtocol) [`Hashable`](/documentation/Swift/Hashable) ### Inherits From [`NFCTagReaderSession`](/documentation/CoreNFC/NFCTagReaderSession) --- Copyright © 2026 Apple Inc.
