`Barclays` and `Streamline`
:
For Maestro (UK Domestic and International) cards, this value must be valid (01 through 12) but is not required to be a valid expiration date. In other words, an expiration date that is in the past does not cause `Cybersource` to reject a request. However, an invalid expiration date might cause the issuer to reject a request.

`Chase Paymentech Solutions`
:
For encoded account numbers (card_cardType=`039`), set the value for this field to `12` if the card does not provide an expiration date.
