Dart Implementation of the ISO-8583 banking protocol. Supports 03xx message class (File Actions Message - 1987) and is compatible with most PoS devices in the market.

• Supports MAC (Message Authentication Code) calculation.
• DES Encryption.
• Written in 100% Dart.
• Works on all platforms (Android, iOS, macOS, Windows, Linux, Web).

The package also provides the following methods:

factory Message.parse(Uint8List data)

factory Message.conntectionTest({DateTime? dateTime})

factory Message.purchase({required int amount, DateTime? dateTime})

factory Message.ack({required String terminalId, DateTime? dateTime})

factory Message.nack({required String terminalId, DateTime? dateTime})

factory Message.eot({required String terminalId, DateTime? dateTime})

factory Message.dispose({DateTime? dateTime})

Map<String, Object> toJson()

In your pubspec.yaml file add:

dependencies:
  pos: any

Import the package:

import 'package:pos/pos.dart';

Then:

final iso8583Message = Message.parse(Uint8List);

Please look at the ./example directory for a working demo using TCP and SerialPort.

I would thank YeGoBox for being kind enought to transfer the ownership of their original pos package to me.
