CVV Calculation

description

Hello,
I wonder how to write the expiry date to calculate cvv ?
Should I start with MM/YY or YY/MM ?

For VISA and MC need to use next format:
  • CVV (data on magstripe) YYMM and service codes not equal 000 or 999
  • CVV2 (printed data on back side of the card) YYMM or MMYY and service code 000
  • iCVV (data on chip) YYMM and service code 999
you can find confirmations in VISA or MC documentation :)
