Smart Card Terminals
Smart card terminals shown here are small, hard to find but totally amazing devices!
Most of them will take and process 2 smart cards at the same time opening doors to new, practical applications. Battery powered means they can be used anywhere, at any time. 2 x AAA means batteries are common and can be easily obtained everywhere. Very practical, simple but powerful applications are possible using these terminals. Eg. off line payment at remote location ... beach rentals, tourist attraction ... anything goes.
