Yes. And, buying pre-loaded Visa cards would make it safer on the
Internet. However, my suggestion was in search of security and
*convenience*. I could just as easily open a new account at a Bank I
don't now use and make email transfers up to $1,000. Places like Tim
Horton's have rudimentary cash cards that record a cash balance, paid in
cash, which tabulates a running balance until reaching $0, that you then
use at Tim's.
I can currently purchase online, do my banking online, email inter-bank
amounts. ATM machines allow me to do almost all of the common financial
transactions I might want.
It seems to me, all the bits and pieces including security are already
available to make my suggestion work. All you need is a home card
reader. Keeping such a thing off the market won't prevent the crooks
from reading stolen cards. They can do that already.
None of the existing safety checks have to be removed. It just means
that the identity and transaction signals are coming from an
identifiable source other than an ATM.
The user would have the security of knowing that they are carrying
around and using a card and an identity they can 'afford' to lose, while
credit and debit cards can be kept in a much safer place until needed.
By using a 'cash' card and credit/debit card in conjunction with each
other a thief has to get hold of both. By just keeping the cards
separately, say, the 'cash card' in a wallet and your credit and debit
cards in a purse, at home, with a spouse etc. etc. theft of banking info
becomes much harder.
