In older versions of the library, you might have needed to hook into MainActivity lifecycle events. In the newest versions of NFCNET, setting Active := True usually handles the foreground dispatch registration automatically.
procedure TMainForm.StartNFC; begin // Check if we are on Android {$IFDEF ANDROID} PermissionsService.RequestPermissions( [JStringToString(TJManifest_permission.JavaClass.ACCESS_FINE_LOCATION)], // Permission string procedure(const APermissions: TClassicStringDynArray; const AGrantResults: TClassicPermissionStatusDynArray) begin if (Length(AGrantResults) = 1) and (AGrantResults[0] = TPermissionStatus.Granted) then begin // Permission Granted! Now we can initialize NFC Nfc1.Active := True; // Check if hardware actually exists if not Nfc1.Enabled then ShowMessage('NFC is disabled. Please enable it in settings.'); end else begin ShowMessage('Location permission is required for NFC scanning on Android 10+'); end; end ); {$ELSE} Nfc1.Active := True; // For Windows/iOS (iOS has its own logic) {$ENDIF} end; The main functionality of the library is captured in the OnTag event. This fires when a tag is detected.

procedure TMainForm.Nfc1Tag(Sender: TObject; const Tag: TNfcTag); var i: Integer; NdefRecord: TNdefRecord; PayloadStr: string; begin // 1. Basic Tag Info Memo1.Lines.Add('Tag Detected!'); Memo1.Lines.Add('ID: ' + Tag.Id); // Tag ID (Hex usually) Memo1.Lines.Add('Technologies: ' + Tag.TechList);
WinSoft's library is a popular commercial component for Delphi and C++ Builder that allows developers to integrate NFC (Near Field Communication) functionality into Android and iOS applications.
// 2. Reading NDEF Messages (Standard Data) if Tag.NdefMessage <> nil then begin Memo1.Lines.Add('NDEF Message Found:'); for i := 0 to Tag.NdefMessage.RecordsCount - 1 do begin NdefRecord := Tag.NdefMessage.Records[i]; // Extract payload as string (assuming it's text) // Note: Payload is often a TBytes array, might need specific decoding based on URI or Text type PayloadStr := TEncoding.UTF8.GetString(NdefRecord.Payload); Memo1.Lines.Add(' Record ' + IntToStr(i) + ': ' + PayloadStr); end; end; end; On Android 10+, apps often lose focus or get paused. To ensure your app catches the NFC tag even when it is open (Foreground Dispatch), WinSoft handles much of this internally, but you must ensure your app handles the Intent properly.
