Digital age: 'finger recognition' technology has been introduced into care homes to monitor how many hours nurses are working at any one time. As nurses at the care homes start and finish their shifts, they place their fingers into a wall-mounted scanner. This identifies tiny points on the finger and stores information about them so that each finger can be recognised when placed in the scanner again. By this method, the scanner can record exactly how long nurses have worked. Helen McArdle Care has introduced the 'biometric attendance system' into its five care homes. Managers argue that it will 'prevent overpayment for time not worked', and ensure that there is a correct skill mix in place. RCN senior employment relations adviser Karen Didovic said the system could be good if it ensures that nurses are paid for the overtime they work, but added: 'I do not think it should be the primary system for measuring staffing levels on the ward.'
