Protect your sensitive data such as credit card numbers or US social security numbers in your tickets. This app will obfuscate all but the last 4 digits. The other numbers will show as an "X". The data is protected in the Ticket Subject, Description, Private and Public Note. What's new? Earlier, this app would mask any 16-digit number. We've now included the LUHN algorithm to identify whether the number is that of a valid credit card or whether the data is a social security number before masking. The following credit card formats are covered by this app. 4242424242424242 Visa 4000056655665556 Visa (debit) 5555555555554444 Mastercard 2223003122003222 Mastercard (2-series) 5200828282828210 Mastercard (debit) 5105105105105100 Mastercard (prepaid) 378282246310005 American Express 371449635398431 American Express 6011111111111117 Discover 6011000990139424 Discover 30569309025904 Diners Club 38520000023237 Diners Club 3530111333300000 JCB 6200000000000005 UnionPay Disclaimer: This app will mask any data that resembles a credit card/SSN number and obfuscation not supported during ticket creation if mandatory ticket fields are configured.
