Preliminary information

Before explaining the operation of some of the main apps for payments with QR code, I think it is useful to make a brief discussion of an informative nature on this technology, in order to make you aware of its main advantages.

First of all, you must know that QR code is the acronym for Quick Response Code: it is a two-dimensional barcode made up of black modules arranged within a white scheme, which contains information that can be decoded extremely quickly using the camera of mobile devices such as smartphones and tablets, but also computers.

The latter, in fact, are able to interpret the text information of the cryptogram (consider that a standard QR code can store up to 4,296 alphanumeric characters) through some integrated functions or by means of dedicated apps and simultaneously execute the instructions contained therein.

How do you say? Did the topic pique your interest and would you like to deepen it further? In this case I suggest you take a look at my guide on how the QR code works: I am sure you will find a lot of useful information that can satiate your thirst for knowledge.

The possibilities of applying this technology, as you may have guessed, are almost endless, but in this tutorial I will focus on the way in which you can interact with the QR code to make a payment, both in a store and online. If you have doubts about the security of this system, I want to reassure you immediately: the encryption of the two-dimensional code allows, in fact, to safeguard the transaction from prying eyes, fraud and dubious operations.

In general, the operation of the QR code payment system is very simple: in a physical store, for example, the merchant allows his customers, at the time of the balance, to scan the aforementioned code. This operation must be completed using the appropriate app developed by the preferred payment platform (such as PayPalSatispay or the bank’s app, just to name a few examples) which must be previously linked to a credit/debit card or to the IBAN of your current account, in order to find the funds needed to complete the transaction.

Is the procedure still not completely clear to you? Don’t worry: in the next chapters, in fact, I will show you practical examples of payment with QR.

How to pay with PostePay QR code

You have a PostePay prepaid card or a PostePay Evolution card and you have recently heard a lot about the possibility of making payments with QR code in post offices or affiliated businesses.

To understand how to pay with the PostePay QR code, you will first have to download the relevant app, available for both Android devices (if you have a device without Google services, check the alternative stores ) and iOS / iPadOS.

To complete the download, just click on the aforementioned links and tap the Install / Get button from your device (if you have an iPhone / iPad you will be asked to verify your identity via Face IDTouch ID or Apple ID password ). Then, to start the app, press the relevant icon, then press the Login button to authenticate.

Then enter Username and Password in the respective fields and press the Login button again. If you have also activated a PosteID code, you will need to enter it on the next screen and press the Login button one last time.

How do you say? You have not yet registered an account on and you are not sure how to do it? Don’t worry: follow my dedicated guide step by step and in no time you will have completed this procedure as well.

You are now on your Home screen, where you can find summary information on the cards associated with your profile and the main features made available by the app. I suggest you take advantage of in particular the one called Maps, present in the menu at the bottom right, to identify the merchants affiliated to this payment system.

After pressing the relevant icon, you will be asked for consent to geolocation and, the first time, you will have to press the Allow item only while using the app to continue. In the following screen you will see the list of merchants starting from the closest, but to filter the results and view only those that have the QR code simply tap on the homonymous button at the top.

Once you have chosen the product/service to purchase and have indicated to the shopkeeper (or post office operator) your intention to pay with the QR code, you need to start the dedicated function: just press, in the menu below, on the Pay item, then, in the following screen, select the Payments tab located at the top. Among the various options that will be proposed to you in the next step, you will have to touch the box that says Pay with QR code.

The first time you use this feature, the app will ask you for permission to access the camera and you will have to press the Allow button to continue: this will start the aforementioned feature and you can frame the QR code previously provided by the merchant or post office on a special display.

In a few moments you will see the transaction report which, as a rule, already contains the amount you are about to pay. In some cases, however, you may be required to manually enter this value. Now, all that remains is to authorize the payment by pressing the Pay button: if you have activated the PosteID code, also in this case you will have to confirm everything by entering it in the appropriate field and pressing the Pay button again. It was all particularly quick and easy, wasn’t it?

Now you have to associate the cards with which you want to make payments via QR code to the Masterpass system, by pressing on the item Buy online: you will be shown an information screen and you will have to press on the Start Configuration item to start the procedure. Then type in the PayPin you have chosen just now and, in the following screen, select the cards you want to enable for this type of payment by pressing the Confirm button.
