Ingenico Credit Card Machine Alert Irruption

Today I'll explain what it means when the Ingenico card machine is saying Alert irruption and what you can do about it.

There are a few misleading videos on YouTube showing how to fix the alert irruption error. That's why I decided to create this post and provide accurate info on what is causing this error and how to tackle it.

Card machine models covered in this post are: ICT220, ICT250, IWL220, IWL250, IWL255, IPP320, IPP350, Move3500, Move5000, Desk3500, ISC250 and other Ingenico models.

So without further ado, let's dive right in:

What is Alert Irruption on Ingenico Card Machine?

According to Payment Card Industry (PCI) security requirements, all payment terminals need to have a PIN entry device protection from unauthorized opening (or tampering). 

This is done mainly to prevent fraudsters from opening the terminal when the store is not attended. Fraudsters can then insert a skimming device to collect the card and PIN data during the shop business hours and use those card numbers later for fraudulent purchases.

"PCI POS PED Security Requirements and EPP Security Requirements" clearly state that "at least three blind, tamper switches must be implemented" on the credit card machine.

So if only one of those 3 tamper switches is activated, you will notice the credit card machine saying Alert irruption, which means that you can no longer use the card terminal due to suspected tampering.

In general, whatever Ingenico terminal model you are using (ICT220, ICT250, IWL220, IWL250, etc.), the error message usually looks similar to this one:

Why Ingenico Card Machine is Saying Alert Irruption?

As previously explained, alert irruption message is shown when one or more tamper switches in the card machine go off.

The truth is, it doesn't always mean that someone was trying to mess with your payment terminal.

From my experience, tamper switches can be activated by one of the following events:

  • Someone tried to tamper with or open the card machine;
  • Physical shock - someone dropped the card machine;
  • Electrical shock - there was a power surge or power outage followed by a sudden voltage increase in the grid;
  • The device has been powered off for too long - this can lead to a depleted internal battery (like the one powering the bios clock in a laptop or PC).

Is there a POS Ingenico Alert Irruption Error Fix?

After getting this error, the first logical question is how to fix alert irruption on the card machine and continue accepting card payments?

You may not want to hear this, but here we go:

There is absolutely nothing you can do on your own to quickly fix the "Alert irruption" error.

I have seen a few videos on YouTube where some Pakistani guy shows how to revive the payment terminal by entering a secret code. Unfortunately this is totally fake and impossible, at least for the alert irruption error.

The thing is, when the "alert irruption" error is shown, tampering protection inside the card machine has already been activated. Once activated, the self-destruction mechanism is triggered. As a result, all encryption keys are instantly cleared out from the card machine memory, rendering it unusable.

Depending on the POS maintenance contract you have, there are basically two options left on how to solve alert irruption:

  • Contact the Ingenico service vendor or merchant help desk service line and ask for a card machine terminal swap; or,
  • Contact the Ingenico service center and ask for a card machine terminal diagnostic and repair. Usually, the service will collect it, or you will need to ship it. The repair is usually done at the repair center because of the reactivation and secure inserting of the encryption keys back into the terminal.
  • Last but not the least, put up a clear and visible card machine out of order sign
