[RegularExpression(@"^\d{16}$", ErrorMessage = "Card Number has 16 digits")]
       public string CC
       { get {
            String CC = "";
               String CCEncoded;
                CCEncoded = "XXXX XXXX XXXX " + CC.Substring( CC.Length-4, 4);
                return CCEncoded;  }
           set  { } }

In view

HTML

@alexandrovich: as of customer giving their card number is safety right..

It's actually not safe, to give a card number to non-trusted party.

HTML

<input id="account" value="1234567899876543" />

<input id="account_changed" />

var account = document.getElementById('account');
var changed = document.getElementById('account_changed');

changed.value = new Array(account.value.length-3).join('x') + account.value.substr(account.value.length-4, 4);

output:

1234567899876543

************6543

in MVC3

in place of value put @model.account
