Foreword This ETSI Technical Report (ETR) was produced by the Human Factors (HF) Technical Committee of the European Telecommunications Standards Institute (ETSI). ETRs are informative documents resulting from ETSI studies which are not appropriate for European Telecommunication Standard (ETS) or Interim European Telecommunication Standard (I-ETS) status. An ETR may be used to publish material which is either of an informative nature, relating to the use or the application of ETSs or I-ETSs, or which is immature and not yet suitable for formal adoption as an ETS or an I-ETS. Introduction In recent years, prepayment telephone cards bearing a small indentation on one edge have appeared in several European countries (e.g. Belgium, Denmark, Netherlands, Norway, Switzerland and United Kingdom). This indentation or tactile identifier, which can be felt with the fingers, has been provided explicitly to aid blind and visually impaired people to orientate the telephone card correctly before inserting
