A tactile transaction card having at least one readable medium, or indice or one writable medium or indice for storing information (magnetic strip 15) and having associated therewith at least two distinct tactile orientation means such as sets of notches 19,119, the arrangement of said orientation means being such that tactile detection by a user provides non-visual information of said card and readable medium or indice orientation relative to said user. Without visual aid it can be difficult to align a device or card correctly in relation to a card reader or writer to enable the readable or writable medium or indice to be written or read. Inclusion of at least two distinct tactile orientation means on a card allows a user who cannot perceive the orientation of the card to align the readable or writable indice correctly in relation to a machine reader or writer, by touch or feel. Other tactile orientation means are a raised projection (26, figure 2), a raised circular projection (34, figure 5) and a depressed circular indent (37, figure 6). |
