The project presented here is a first step towards building a more accessible world through Payment Systems and a successful implementation of a User Centered 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. • 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.
