I owned one but returned it because it does NOT support EMV/chip. This means that it does NOT work on most newer readers! I was not able to make a single transaction with the wocket! Come October most establishments will be using chip technology.
Wocket does not support chip cards which are now becoming the standard. I believe that in October retailers are mandated to use chip readers or face a financial penalty. All the retailers that I tried to use my card at had chip readers and I was not able to use my card anywhere, including the ATM machine!
