a flutter plugin for decode and genrate emv-mpm qrcode
Usage
Decode func
final decoded = emvQRDeCode(emvCode);
print("emvcode ------------->${decoded.emvqr?.toJson()}");
Generate func
var payloadFormat = ParseEMVQR().setTLV("01", ID.payloadFormatIndicator);
// point of initiation method
var pointOfInit = ParseEMVQR().setTLV("12", ID.pointOfInitiationMethod);
// merchant
var merchantInfo1 = MerchantAccountInformationValue(
globallyUniqueIdentifier: ParseEMVQR().setTLV(
"D123456", MerchantAccountInformationID.globallyUniqueIdentifier),
paymentNetworkSpecific: [ParseEMVQR().setTLV("1231234567890", "13")]);
var merchantInfo2 = MerchantAccountInformationValue(
globallyUniqueIdentifier: ParseEMVQR().setTLV(
"M123456", MerchantAccountInformationID.globallyUniqueIdentifier),
paymentNetworkSpecific: [
ParseEMVQR().setTLV("1234567890123456", "04")
]);
// merchant category code
var merchantCategory =
ParseEMVQR().setTLV("1111", ID.merchantCategoryCode);
// transaction currency
var transactionCurrency =
ParseEMVQR().setTLV("392", ID.transactionCurrency);
// transaction amount
var transactionAmount =
ParseEMVQR().setTLV("1000.00", ID.transactionAmount);
// country code
final countryCode = ParseEMVQR().setTLV("LA", ID.countryCode);
// merchant name
var merchantName = ParseEMVQR().setTLV("KAk MOoo", ID.merchantName);
// merchant city
var merchantCity = ParseEMVQR().setTLV("Vientaine", ID.merchantCity);
// emv data
var emvData = EMVQR(
payloadFormatIndicator: payloadFormat,
pointOfInitiationMethod: pointOfInit,
merchantAccountInformation: {
"29": ParseEMVQR().addMerchantAccountInformation("29", merchantInfo1),
"31": ParseEMVQR().addMerchantAccountInformation("31", merchantInfo2)
},
merchantCategoryCode: merchantCategory,
transactionCurrency: transactionCurrency,
transactionAmount: transactionAmount,
countryCode: countryCode,
merchantName: merchantName,
merchantCity: merchantCity,
);
final emvqr = ParseEMVQR().generatePayload(emvData);
print("value----> ${emvqr.toJson()}");
