Tap to pay on NFC enabled mobile phone shows TAP TO SIMULATE PAYMENT screen always instead on waiting for real card

[ajithv11]

Hi,
Tap to pay on NFC supporting mobile phone shows TAP TO SIMULATE PAYMENT screen always instead of waiting for real card, It happens when I update stripe terminal version to 2.20.1. The code used is given below

   if (discoveryTask == null && Terminal.getInstance().connectedReader == null) {
        val config = DiscoveryConfiguration(
            timeout = 0,
            discoveryMethod = DiscoveryMethod.LOCAL_MOBILE,
            isSimulated = true,
            location = Constants.LOCATIONID
        )
        discoveryTask = Terminal.getInstance().discoverReaders(config,
            discoveryListener = object : DiscoveryListener {
            override fun onUpdateDiscoveredReaders(readers: List<Reader>) {

                val firstReader = readers.first();
                this@TapViewModel.reader.postValue(firstReader);
                val config = ConnectionConfiguration.LocalMobileConnectionConfiguration(Constants.LOCATIONID);
                Terminal.getInstance().connectLocalMobileReader(firstReader, config,
                    
                    object : ReaderCallback {

                        override fun onSuccess(reader: Reader) {
                            val params = PaymentIntentParameters.Builder().setAmount(amt*100).setCurrency(Constants.CURRENCY).build();
                            Terminal.getInstance().createPaymentIntent(params, object: PaymentIntentCallback {
                                override fun onSuccess(paymentIntent: PaymentIntent) {
                                    val collectConfig = CollectConfiguration.Builder().updatePaymentIntent(true).build();
                                    val cancelable = Terminal.getInstance().collectPaymentMethod(paymentIntent,
                                        object : PaymentIntentCallback {
                                            override fun onSuccess(paymentIntent: PaymentIntent) {

                                                Log.d("Response Tap", "paymentIntent Before : "+paymentIntent.id)

                                                Terminal.getInstance().processPayment(paymentIntent, object :
                                                    PaymentIntentCallback {
                                                    override fun onSuccess(paymentIntent: PaymentIntent) {
                                                        // Placeholder for notifying your backend to capture paymentIntent.id TODO
                                                        Log.d("Response Tap", "paymentIntent Success : "+paymentIntent.id)
                                                        
                                                    }

                                                    override fun onFailure(exception: TerminalException) {
                                                        Log.d("Response Tap", "paymentIntent Error : "+paymentIntent.id)
                                                        
                                                    }
                                                })
                                            }

                                            override fun onFailure(exception: TerminalException) {
                                                Log.d("Response Tap", "paymentIntent Error : "+exception.errorMessage )
                                            }
                                        })



                                }
                                override fun onFailure(exception: TerminalException) {
                                    Log.d("Response Tap", "paymentIntent Error : "+exception.errorMessage )
                                }
                            })
                        }
                        override fun onFailure(e: TerminalException) {
                            Log.d("Response Tap", "paymentIntent Error : "+e.errorMessage )
                        }
                    });
            }
            },
            object : Callback {
                override fun onSuccess() {
                    discoveryTask = null
                    //Log.d("Response Tap", "Readers Discovered Success!");
                }
                override fun onFailure(e: TerminalException) {
                    discoveryTask = null
                    Log.d("Response Tap", "Reader Discovery Failed : " + e.errorMessage);
                     
                }
            })
    }

Do I need to change anything on the above code for making tap card enabled? It was working and wait for real card on version 2.17.1

Screenshot of version 2.17.1 which if fine

Screenshot of version 2.20.1 : Issue I need real tap card here

Same happens on both stripe test mode and live mode

It appears that you have set:

isSimulated = true

I imagine this should be set to false.

@rscherf You said it :) Thanks a lot

So I believe in previous version, There is no simulation option in LocalMobileConnection, In the later version 2.20.1 simulation is available, so the isSimulated = true comes into effect.

Thanks @rscherf!

@ajithv11 Yes, we added support for the simulated Tap to Pay reader in 2.18.1:
