- All true - this is why the smart ATM card needs its own keyboard
- and on-board encryption device. Then the bi-directional challenges
- are fully encrypted, and a completely bogus machine cannot interfere.
- What this means is something like a credit-card sized calculator.
-
- Certainly the ATM cards typically in use today in the US are insufficient.
- Some of the European smart cards are approaching what is required, but
- the real issue is building a smartcard with a keyboard that can survive
- in a person's wallet or purse or whatever and doesn't cost significantly
- more than current mag-stripe ATM cards. This is a major engineering
- challenge to the power and packaging people!!
