Paul Foxworthy commented on OFBIZ-7824: --------------------------------------- Some credit cards have different lengths. For example, American Express is 15, not 16 digits. Credit cards have a built-in checksum using the Luhn algorithm (https://en.wikipedia.org/wiki/Luhn_algorithm). It would be far better to verify the checksum, rather than just the number of digits. There already is credit card checksum checking in OFBiz. Have a look at https://fisheye6.atlassian.com/browse/~br=trunk/ofbiz/trunk/framework/base/src/main/java/org/apache/ofbiz/base/util/UtilValidate.java?r=1761200#to1193 and the preceding code. Is there somewhere in OFBiz that should be using this validation, but isn't currently? > Add validation for credit card number length > --------------------------------------------- > > Key: OFBIZ-7824 > URL: https://issues.apache.org/jira/browse/OFBIZ-7824 > Project: OFBiz > Issue Type: Improvement > Components: ALL APPLICATIONS > Affects Versions: Trunk > Reporter: Padmavati Rawat > Priority: Minor > > Ofbiz allows for any length for credit card numbers, as default length is 16 > digits. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
