After you have your new EMV chip readers installed, have your service provider on speed dial in case any glitches come up. If you’ve chosen a solid provider, they should be able to trouble shoot any problems very quickly (hopefully you researched well and choose wisely). Make sure your employees have your service provider’s contact information readily available, too.
When your customer’s chip isn’t working, they may want to know why their mag stripe still works. You can have your employees explain that using their stripe is always an option, but the chip is more secure. If they can’t dip their card and they must use their mag stripe, have your employees explain that it’s just temporary and apologize for the inconvenience.
