авторизационная форма дебетовой карты, вопрос

[esllove.livejournal.com]

одно из полей авторизационной формы дебетовой карты выглядит так: "Issue No. (Switch only)" - что это может быть? Количество необходимых цифр непонятно, т.к. она не онлайн, а распечатанная.

Заранее спасибо.

http://en.wikipedia.org/wiki/Issue_number :
Switch (debit card)
...
Switch is a former debit card in the United Kingdom, now re-branded as Maestro.
...
Switch/Maestro cards issued by certain banks, notably the HSBC group, carry an issue number on the bottom of the card corresponding to the number of times a card has been issued on a particular account. This is usually because the current account number the card is linked to actually forms a large part of the card number, and therefore the card number cannot be readily changed in case of loss or the card expiring.

Despite not being used as a brand for a number of years, the term "Switch" is sometimes used on e-commerce sites to refer to Maestro cards.
