What are the limitations of use of "Electronic use only " debit card

Question

I have a visa electron debit card and there is "electronic use only" marked on it, so I don't know where or when I can't use my debit card ?

Answer 1

"electronic use only" cards can only be used by vendors that can instantly verify and authorize the purchase, which is most vendors these days, but there will be some exceptions:

• vendors that use old "batch" style processing
• vendors that "copy" the embossed numbers using carbon slips (very rare now)
• offline purchases (e.g. on a plane)

The problem is you won't know beforehand if the vendor uses instant authorization or not, so be prepared with an alternate form of payment if the vendor does not accept your card.
