So you applied just in time u/s 139(1) on or before due date of July 31st, your request will get processed and intimation will be sent u/s 139(5) by CPC (Card Processing Center) that your card has been approved and You Have a Cashback this year will flash. Keep checking status on sbicard.com. Verification can take 7-30 days in worst cases. I pray to Bhagwan Creditesha, it gets approved for you soon.
For many of us holding SBI acc., who applied in July via Netbanking, KYC and professional info. was already there (though re-entered prof. details), card was generated instantly.
