Abstract: A portable payment or retail terminal with jack connector and a method for secure identification of a cardholder, the terminal including a set of devices and arrangement for implementing the method, which has at least: detecting the presence of a jack plugged in the connector of the terminal for connecting a cardholder's headset, triggering the execution of an accessibility mode allowing the cardholder to identify, the method being wherein it includes at least: scrambling and maintaining the screen in black during the sequence of the accessibility mode, generating a chain of keys comprising a set of keys for PIN/SNL entry, attributing a value of key corresponding to the length d of the finger's displacement; selecting among pre-registered audio signals corresponding to each key of the chain of keys, the sound corresponding to the key attributed to the displacement and emit it through the jack connector towards the cardholder's headset.

Abstract: A device and method for identifying a user. The device including a terminal including a touch screen with a set of embossments superimposed on a virtual keyboard and displaying information related to a transaction, a contact and/or contactless smart card reader device, a processor and a memory containing a set of modules and/or algorithms to implement the method including activation of a low vision mode by a double-tap gesture on the screen, the searching for the center of a virtual keyboard where an embossment is located, determination of the positions of the other keys from the central key, choice and storage of a desired key by lifting the finger from the touch screen at the position of the desired key, validation of the choice of key made by a double-tap gesture on the touch screen or validation of the code/PIN by a double-tap gesture on the touch screen.
