javascript - How to tell if square reader is encrypted or not -

-

my company purchased old square reader, seller claims unencrypted. trying develop web application uses reader. reader supposed fire hard return keypress event after registering swipe - has never done (using javascript event listeners). time reader using ios square register app - app recognize reader , swipe (though terrible job, asking me 'retry swipe faster' few dozen times before registering swipe)

the fact works in app leads me believe encrypted reader. there way tell if assumption correct? without taking apart.

also, tips on troubleshooting appreciated.

thanks

i think you're pretty lucky able detect @ javascript event listeners seem imply....

imagine privacy intrusions we'd have on (maybe already) if javascript stealthily downloaded web site gain access microphone and/or microphone jack want do. might possible, phone 'ifrastructure' designed 'resist' this.

i think you're going have write app installs user permissions access devices need - otherwise mic jack device unlikely available you.

btw, credit card stripes encoded in 7 bit, if getting string looks 'encrypted' examine unaltered string 7 bit , it'll start making sense.
