For instance, pension contributions of many professionals, such as engineers, which are set at a fixed amount depending on the number of years of activity, regardless of earnings, could usefully be rationalised. The recent activation of two centralised, inter-linked, electronic monitoring systems is a welcome step in this regard. More specifically, the “Helios” scheme, monitoring retirement pay, is linked to the “Ariadne” scheme, that directly records major demographic changes, facilitating in this way the detection and suspension of ineligible pensions (EC, 2013b). Regional differences in the distribution of different categories of pensions in mid-2013, particularly regarding disability pensions, suggest the need for further monitoring of the social security system to avoid abuse in the future. The uninsured have a means-tested access to some basic health care services through the “health insurance book”, providing free access to public hospital and medical services (including pharmaceuticals).
