BS ISO-IEC 7811-9-2015 pdf free download – Identification cards — Recording technique — Part 9: Tactile identifier mark.
This part of ISO/IEC 7811 specifies the physical characteristics of a tactile identifier mark used byvisually impaired card holders to distinguish their cards. It defines the area on the card for the TIM andthe layout of Braille style embossed dots arranged in patterns to enable easy tactile recognition.
2Conformance
A TIM is in conformance with this part of ISO/IEC 7811 if it meets all mandatory requirements andoptional requirements as specified.
3 Terms and definitions
For the purposes of this document,the terms and definitions given in ISO/IEC 7810 and thefollowing apply.
3.1
TIM
tactile identifier mark
3.2
embossed
raised in relief from the front surface of the card by adding or reacting card material or by deformingthe card material from the opposite side
4TIM physical characteristics
4.1Location of TlM
The TIM should be located on the front surface of the card in the area shown in Figure 1.The TIM shall not be located outside the name and address area defined by ISO/IEC 7811-1.Regardless of TIM location, all other raised areas shall be at least 1 mm from the edge of anyTIM.When the technology used to form the raised areas causes a physical deformation of the card suchas mechanical embossing, then special care shall be taken that such deformation of the card doesnot adversely affect the required characteristics of the contained components such as lC, antenna,connecting wires,etc.
A minimum distance of 3 mm between the contained components and any deformed part of the card isrecommended unless it is known that the components are not affected by the deformation of the card.
The recommended TIM location is shown in Figure 1 as “Default area”. If the “Alternate area” for TIM is used, there shall be no other raised area to the right and below the TIM dots (between TIM dots and nearest edges of card).
NOTE The alternate area is raised up to avoid overlapping on the antenna of a contactless IC card but is still low enough to be in the name and address area as required and to be at least 1 mm away from the primary account line (both specified in ISO/IEC 7811-1).
4.2 TIM dot arrangement
The TIM shall be composed of a maximum of three groups of six dots arranged as shown in Figure 2.
4.3 Dot dimensions
Dots used to make up the TIM shall have a relief height of 0,48 mm (0.019 in) maximum and 0,3 mm (0.012 in) minimum above the adjacent surface of the card. The shape of each dot is not specified,examples are shown in Figure 3.
4.4 Sign design
It is recommended that the cardholder select which of the 18 possible dots are to be raised. The maximum number of raised dots is 18 and the minimum is 1.
NOTE Since there are individual differences in discernment by the tactile sense, it is recommended that the card holder be able to use the combination of the dots that is easy for them to discriminate.BS ISO-IEC 7811-9 pdf download.
