7、1250 Eye Street NW, Washington, DC 20005ANSI NCITS 118-1998Foreword (This foreword is not part of American National Standard ANSI NCITS 118-1998.)This standard identifies the fixed arrangement of the alphanumeric characters and keys of a PIN pad. APIN pad is used by a customer to enter a Personal Id
8、entification Number (PIN) when requested as part ofa transaction. The standard was developed in NCITS/B10 with the assistance and comments of NCITS/V1, X9, and T1. It revises ANSI X3.118-1984.CAUTION: The developers of this standard have requested that holders of patents that may berequired for the
9、implementation of the standard disclose such patents to the publisher. However,neither the developers nor the publisher have undertaken a patent search in order to identifywhich, if any, patents may apply to this standard. As of the date of publication of this standardand following calls for the ide
10、ntification of patents that may be required for the implementation ofthe standard, no such claims have been made. No further patent search is conducted by the de-veloper or publisher in respect to any standard it processes. No representation is made or impliedthat licenses are not required to avoid
11、infringement in the use of this standard.Page 2 of 3 pagesANSI NCITS 118-19981. Scope, Purpose, and Application1.1 ScopeThis standard identifies the fixedarrangement of the alphanumeric charactersand keys of a PIN pad. The PIN pad is usedby a customer to enter a PersonalIdentification Number (PIN) w
12、hen requestedas part of a transaction.1.2 PurposeBy designating a specific keyboardarrangement for the PIN pad, compatibilitymay be ensured between various terminalsand networks when a customer enters aPIN.1.3 ApplicationThis standard applies to terminals in whichthe customer is required to enter a
13、PIN aspart of a transaction.2. Definitions2.1 customer: The individual initiating atransaction.2.2 personal identification number (PIN):The 4- to 12-position code or password thecustomer possesses for authentication.2.3 PIN pad: A device for the customer toenter a PIN. It contains a keyboard with 12
14、keys: ten keys for entering alphanumericcharacters and two special function keys.3. Physical Characteristics of the PINPad3.1 KeyboardThe keyboard shall consist of 12 keysarranged in an array with three verticalcolumns and four horizontal rows (seeFigure 1).1ABC2DEF3GHI4JKL5MNO6PQRS7TUV8WXYZ90COLUMN

16、ric CharactersThe alphanumeric characters listed in Table1 shall coincide with the keys of the PIN pad.Page 3 of 3 pagesANSI NCITS 118-19983.3 Keyboard FormatThe alphanumeric designations shall beplaced on the keytops or adjacent to thekeytops as specified in Table 1.3.3.1 Keytop AssignmentsThe arra
17、ngement of the keyboard andkeytop assignments of the PIN pad shall beas shown in Figure 1.3.3.2 Assignment When Keytops AreAdjacent to LabelsIf the alphanumeric labels are not placed onthe keytops as illustrated in Figure 1, theyshall be placed adjacent to the specifiedkeys. The character designatio
18、ns may belocated above, below, or to the left or right ofeach key of the PIN pad. The characterdesignations shall be clearly marked,associated with the key to which it isassigned.3.4 Other Function KeysThe keys to the left of the zero key (Column1, Row 4 of Figure 1) and the key to the rightof the z
19、ero key (Column 3, Row 4 of Figure1) may be function keys. Their designationand use is optional.When these keys are used to correct errorsin PIN entry or to delimit a step in the PINentry procedure, the following assignmentsare recommended: The lower right keyshould be the delimiter and may be label
20、ed“Enter;” the lower left key should be used ifa cancel function is supported and may belabeled “Cancel.”4. Security4.1 ShieldingIt is recommended that PIN pads bedesigned to shield the PIN from visualobservation of digits entry by the customers.4.2 Audible TonesAny audible tones generated from PIN
21、entryshall not identify specific keys.5. Migration Plan5.1 Education PeriodEffective July 1, 1997, card and PIN issuersshall cease to issue alphabetic PINs thatinclude the letters Q or Z. If issuers allowusers to select their own PINs, users shouldbe discouraged from selecting alphabeticPINs that in
22、clude Q or Z.For terminal equipment used for PIN entry,from the present until January 1, 2000,acquirers should maintain PIN pads with QZon 1, in accordance with ANSI X3.118-1984(R1990).5.2 Transition Period. From the presentuntil January 1, 2000, organizations workingwith PIN-issuing and PIN-using i
23、nstitutionsshall inform them of the effective revision ofthis standard and shall work with issuers onQ/Z-related issues. In order to managepotential PIN-related authorization declines,issuers and institutions will notify cardholdersof potential declines if PINs include Q or Z.Beginning January 1, 20
24、00, PIN pads on allnew terminal equipment should place Q on 7and Z on 9, in accordance with this standard.At the same time, existing PIN pads shouldbegin migrating to convert to this new format.5.3 CompletionBy January 1, 2003, all terminal equipmentused in conjunction with PIN entry shallconform to the layout specified in thisstandard.After January 1, 2003, card and PIN issuerscan begin to issue alphabetic PINs thatinclude Q and/or Z. If issuers allow users toselect their own PINs, restrictions on theiruse of Q and Z should be removed.
