My work uses ioProx proximity ID badges to get into the building, whose specs can be found here. We use the P10SHL.
My card is continually getting fried. I have gone through about 8 cards in a three year period, and my last card only lasted two weeks. The culprits are probably my cell phone and wireless car keys.
I'll be getting a new cell phone this summer, but in the meantime, is there anything I can do to shield the card to prevent it from getting fried?
