IDFC Bank has entered into a strategic alliance with mobile wallet company MobiKwik to launch a co-branded virtual Visa prepaid card for customers of MobiKwik. Avtar Monga, ED of the bank, said the tie-up puts IDFC Bank brand in the hands of very large customers that MobiKwik brings. The brand visibility goes up and it allows expansion of the buying power of MobiKwik customers as people will be able to use at more locations, he added.
