Digit-Eyes is an audio labeling system that is portable,
requires no physical connection to a computer and works
everywhere you can take a cell phone. Many functions don't
even require access to a cellular network.
John wants to know which credit card he is using and what the
3-digit CVV code is on the back that the cashiers often ask
for. And, naturally, he does not like having to hand his
credit card over to someone else. But all credit
cards are alike to the touch.
How to know which card is which?
- John selects a small Digit-Eyes label and sticks it on the
back side of his card, being careful not to put it over the
magnetic strip.
- He scans the Digit-Eyes label and records the fact that it
is his VISA card and that the CVV code is "123"
- He repeats this process with his MasterCard and his debit
card, recording what each is and what the codes are.
His personal information is secure because it exists only on
his iPhone, which is under his control.
When John is in line to pay for his purchases, all he has to
do is scan his cards to find which to use and what the code is
he needs to tell the cashier.
His card remains in his possession and Digit-Eyes has done its
job.
