We're a small bank with both debit and credit portfolios. I am holding off EMV implementation on my debit BINs; no earlier than Q1 2016. Very few merchants in our area can support chip, so we're looking at dual issuance (both Chip and Mag) Fraud will still be a factor, and since we block & reissue on data breaches, issuing EMV will drive up the reissuance cost as things currently stand.
On the credit side, we have an affluent card base that travels, and we have had several requests for EMV cards. Our BINs are shared with other banks, and I am waiting for our vendor to certify the implementation process, which should hopefully be soon. I'll begin with a selective issuance targeting those that travel. We will follow up with our other cards once we see more merchants supporting EMV in our area.
As to Chip vs Signature, It's my understanding Signature is Visa's preferred method. I have yet to request an implementation proposal, but reports I've received from other Visa issuers are that certifying Chip+PIN really drives up the implementation costs. I've had very little feedback from MC issuers.
