The project presented here is a first step towards building a more accessible world through Payment Systems and a successful implementation of a User Centred Design. By means of a beep-system, a Point of Sale (POS) payment device informs the user of those transaction steps that require his/her attention at the moment of payment, such as when: the card has been successfully read, the Personal Identification Number (PIN) must be entered, the transaction has been successfully processed and the transaction has not been completed due to an error. The proposed solution increases the personal autonomy and security of blind people when paying at a merchant.
