Human Factors (HF); Telephone Prepayment Cards; Tactile Identifier

Scope

This European Telecommunication Standard (ETS) specifies the form, dimensions and position of an edge indentation for a single standard tactile identifier for machine readable ID-1 type telephone prepayment cards and GSM telephones SIMs, i.e. cards which otherwise conform with the ISO standards for machine readable ID-1 cards, and to specify the test procedure for verifying conformance with this ETS. This tactile identifier is meant to facilitate the correct orientation and insertion of telephone prepayment cards and SIMs in the card-operated terminals, especially for people who are blind and visually impaired, but also for older people, minors and other users.
