You have the choice if your smartphone has got a fingerprint reader. Otherwise you can choose your PIN.

If you choose to use the fingerprint and try to add or modify the set of fingerprints recognized by your smartphone/tablet, this device interprets this as a suspicious operation and locks the app use for your safety. For the same reason, if you chose to use the fingerprint for Mobysign, don’t change the way the smartphone display unlocks. During Mobysign registration, the user receives advice about that.

Yes, you can, as long as the device has got a fingerprint reader, and not too many unsuccessful attempts to authenticate occurred, and you are not in cases of the previous point. You can move from fingerprint to PIN and then change the set of recognized fingerprints or the way you unlock the display. Then you can switch from PIN to fingerprint again.

Mobysign never transmits this information to the network (Mobysign and its systems do not even know these data). PINs and fingerprints are only known to you. Be careful not to reveal your PIN to anyone and make sure others do not look at you when you type it. In any case Mobysign changes the position of the buttons at each operation to prevent anyone from interpreting your PIN while watching you typing.

The PIN or fingerprint is used to unlock a signature of the single transaction using the same mechanism as the smart cards: the signature is sent to the Mobysign servers which, thanks to the technology of Public Key Infrastructure (PKI) technology, is associated with the correct user and the correct transaction. This technology is internationally classified as the safest. Mobysign has brought it into the mobile, available to everyone, without bulky readers to install.

No, you can start any operation on any device or medium such as a web page on a PC, tablet, app or browser or the same smartphone, supermarket or point of sale, or ATM. In any case, you will receive a popup on your smartphone pending your confirmation.

As soon as you register, you can start immediately! No wait at all! Also for credit/debit cards and other payment methods, you can start using just after registering them. Payment methods registration takes just you a few minutes!

Mobysign is PCI certified and patented for the highest level of security. Your data is secure on Mobysign servers, so when purchasing you don’t transmit your card data over the network. Every purchase is explicitly confirmed by you with your PIN or fingerprint. Secure Mobysign servers transmit your card numbers only to the merchant banks (not to the merchant) you are buying from and only for that single purchase.

No, you can associate more cards. You can always confirm your payments with only your fingerprint or a single PIN valid for all your cards, as you chose when registering.

Each payment is authorized exclusively by you. You must remember the PIN if you chose it during your registration or use your fingerprint. Mobysign does not have any information about your PIN or fingerprint. This information is confined to your smartphone just when using and is not transmitted to anyone, even mobysign.

No fear, you can delete your account and data at

Before you can confirm a payment, you can choose the profile to pay with, by swiping one or more times on the grey rectangle that contains operation data: in this way you can switch to another profile.

If you choose a business profile and the merchant has subscribed to the billing service, you will receive an electronic invoice on your smartphone, email account and your fiscal accountant will receive by email immediately as well.

Yes, you can; once you choose the profile you wish to complete the operation, just click on the payment method displayed and choose another one among others which will be displayed

The green QRcode is useful to complete the user registration for a service that has issued it instead of an activation code.

The black QRcode is used to log in or pay or confirm operation in general.

If the QRcode is displayed out of your smartphone, such as on a PC or till, you can read it by opening Mobysign app and clicking on the main Mobysign view on the button representing a QRcode.

If your QRcode is on another app or browser, but on the same smartphone where you’ve installed Mobysign app, you just have to tap.

In any case you will receive a popup with operation information to confirm: verify and compare it with information readable under the QRcode; if it is the same, you can confirm.

The barcode is your identifier, which applies to all points of sales which have this mobysign mode enabled. You can let a reader scan your barcode, and you will see a popup with the purchase details to confirm. Verify and if they are correct you can confirm.

Some merchants and partners issue a specific barcode on the second sheet of the main view during the specific registration of their services. With these barcodes you are allowed to use their exclusive services, loyalties, loyalty points and special offers. You can use the specific barcodes to be scanned by a reader at points of sales, instead of  your main barcode.

Sure, you can follow the import procedure present in the second sheet of the main view and have all of your loyalty cards in Mobysign app always with you

An affiliate service can send you a popup such as a payment or document signing request. If information on the popup you can confirm, otherwise, as always,  please directly contact the affiliate service for clarification.

You also receive one or more emails at every operation.
