Framework to read DesFire NFC tags with iOS 13 and Core NFC
License: Apache License 2.0
I'm developing an application in which I want to get the NFC serial number and Identifier of a NFC tag. When I press a button, I want the application to find the UID and serial number of the NFC card. The only problem is that I have no idea how to get the UID and and serial number if that's possible on iOS. I m trying to get NFC identifier but i don't know how to get serial number of NFC Tag.
Code:-
class ScanNFCTag: NFCTagReaderSessionDelegate {
import CoreNFC
var session: NFCTagReaderSession?
func scanNFCTag(sender: UIButton!) {
self.session = NFCTagReaderSession(pollingOption: .iso14443, delegate: self)
self.session?.alertMessage = "Hold Your Phone Near the NFC Tag"
self.session?.begin()
}
func tagReaderSessionDidBecomeActive(_ session: NFCTagReaderSession) {
print("Session Begin!")
}
func tagReaderSession(_ session: NFCTagReaderSession, didInvalidateWithError error: Error) {
print(error.localizedDescription)
}
func tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) {
if tags.count > 1{
session.alertMessage = "More Than One Tag Detected, Please try again"
session.invalidate()
}
let tag = tags.first!
session.connect(to: tag) { (error) in
if nil != error{
session.invalidate(errorMessage: error?.localizedDescription ?? "")
}
if case let .miFare(sTag) = tag{
let UID = sTag.identifier.map{ String(format:"%.2hhx", $0)}.joined()
session.alertMessage = "Successfully linked tag to location"
session.invalidate()
DispatchQueue.main.async {
print("NFC Identifer = ", "\(UID)")
}
}
}
}
}
So, Here is the my code please let me know if i m doing wrong please correct me. Can someone please explain to me how to get serial number and UID of NFC tag,
Any help would be greatly appreciated.
