SBI mostly issue RuPay variant credit card through offline branches.
I found total 8 RuPay JCB BIN alloted to SBI Card and JCB BIN also issue multiple cards on same BIN.
So, more SBI RuPay JCB credit cards coming soon in future.
Recently, SBI card also launch RuPay SimplySAVE credit card partnership with Punjab and Sind bank. I dnt know which RuPay variant it is.
