8、 FOR USE WITH TELECOMMUNICATION CARDS Source ITU-T Recommendation E.136 was prepared by ITU-T Study Group 2 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 26th of May 1997. Recommendation E.136 (0597) 1 FOREWORD ITU (International Telecommunication Union) is the United
9、 Nations Specialized Agency in the field of telecommuni- cations. The IT Telecommunication Standardization Sector (IT-T) is a permanent organ of the IT. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing te
10、lecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the IT-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members
11、of the IT-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within IT-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administration” is used fo
12、r conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The IT draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The IT
13、takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, the ITU hadhad not received notice of intellec
14、tual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. O ITU 1997 All rights reserved.

17、mmendation is to specify the form, size and position of a tactile identifier for Machine Readable Cards (MRCs) used in telecommunication applications, i.e. prepaid telephone cards. Machine readable card technologies can present problems for all users: namely, to orient and turn the card the right wa
18、y so that it may be inserted correctly into the card-reading device. For people who are blind or severely visually impaired, the task of orienting the MRC correctly can be a substantial obstacle. With at least four different tactile identifier designs in concurrent use, people will be confused. Ther
19、e is, therefore, a need for a single international standard for a tactile identifier on MRCs to aid all users, especially blind and visually-impaired people, in orienting cards quickly and correctly. A tactile identifier on MRCs will also substantially aid visually-non-impaired people to orient and
20、insert cards more quickly and with fewer errors. iv Recommendation E.136 (05/97) - STD-ITU-T RECMN E.13b-ENGL 1997 48b259L Ob38755 853 Recommendation E.136 SPECIFICATION OF A TACTILE IDENTIFIER FOR USE WITH TELECOMMUNICATION CARDS (Geneva, 1997) 1 Scope The scope of this Recommendation is currently
21、limited to prepaid telephone cards of the ID-1 format. NOTE - Further investigation is needed to determine whether the scope of this Recommendation should be extended to include telecommunication chargefcailing cards and other cards used in telecommunication applications (e.g. debidcredit cards). 2

28、 7810). 3.1.2 machine readable card (MRC): An ID-1 card bearing information in a format (magnetic, inductive, electronic, mechanical or optical) which can be read by a magnetic, electronic, mechanical or optical card reading device. ID-1: A standard for a personal identification card made from solid
29、 or laminated PVC or similar: 85.60 mm by 3.1.3 prepaid card: An ID-1 card or thin flexible card bearing a magnetic stripe, integrated circuit or inductive storage coils which can store a preset number of tariff units for paying for phone calls or other telecommunication services. When the card is u
30、sed, units are deleted sequentially from the memory until all have been used and the card expires.

31、zation. International Telecommunication Union. 4 Requirements of tactile identifier Below is a compilation of the most desirable requirements for the design of a standard common tactile identifier for all types of prepaid telephone cards. These requirements are of equal importance and are, thus, not
32、 prioritized. - High tactile conspicuity - The tactile identifier must be easy to feel and recognize tactually by all users, but especially by blind and visually-impaired people, elderly people, etc. - High visual conspicuity - The tactile identifier must be easy to see and recognize by non-visually
33、-impaired users. - Asymmetrical position - The tactile identifier must have an asymmetrical position so that the orientation of the card is unequivocally defined. - User testing - The tactile identifier to be recommended should be selected on the basis of actual user testing to verify that the desig
34、n meets the user requirements of the intended user groups. - Compliance with existing standards - A standard for a common tactile identifier for prepaid telephone cards must in all other respects comply with existing standards for such cards, e.g. ISOiEC 7810: 1985. - Technical compatibility - The t
35、actile identifier should not interfere with the functioning of existing card reading technologies, i.e. embossing, magnetic stripes, integrated circuits “smart chips“, optical storage, inductive storage, security holograms, etc. - Mechanical compatibility - The tactile identifier should be positione
36、d so that it will not interfere with the proper working of the mechanical card-handling technologies, card-feeding mechanisms, swipe-card readers, carbon-copy rollers, card-dispensing vending machines, etc. - Avoid proliferation of new designs - Preferably, a standardized tactile identifier should u
37、se an existing design to avoid proliferation of new designs. Only when it is not possible to use any existing design should a new tactile identifier be created. 5 Recommendation for a tactile identifier On the basis of user trials with different tactile identifier designs and allowing for technical
38、constraints imposed by different card reading technologies, a standard for a tactile identifier on prepaid cards is recommended (see Figure i). 6 Physical description of tactile identifier The tactile identifier, when used, shall conform with the form, dimensions and location shown in Figure 1. The
39、figure shows the position and the geometry of the tactile identifier for telephone prepayment (ID-1) cards in two views: the upper view shows the front side of the card; the bottom view shows the rear side of the card (not to scale). All measures are in millimetres (mm). IC = integrated circuit, MS
40、= magnetic stripe. The standard tactile identifier shall be a 2 mm (IO.1 mm) deep, segment-shaped edge indentation with a radius of 12 mm (k 0.1 mm) in the right hand short edge of the card, its centre located 15 mm (I O. 1 mm) from the lower long edge and 10 mm (k 0.1 mm) outside the right hand sho
41、rt edge of the card. The corners of the indentation where it meets the straight edge shall be rounded (r 0.5 mm) to avoid sharp comers that may cause injury. 2 Recommendation E.136 (05197) STD - ITU-T RECMN E-LIb-ENGL 1797 48b257L Ob38757 b2b IC + MS - I Figure 1E.136 Recommendation E.136 (05197) 3
