Do you use Interac Flash / Debit?
My understanding is that only RBC, Scotiabank and TD have embraced Interac Flash while BMO and CIBC have yet to do so (such as my bank).
IMO, I find flash debit extremely convenient and I'm really tempted to switch banks that have this service (although it my be too much of a hassle anyways).
Do you guys use flash debit? Do you find it useful or useless?
