My company provides bicycle valet service in Portland Oregon. Bicycle valet is a very new industry in the United States so we had to the opportunity to start from scratch to develop a system to check in and out bicycles. We choose to use Serialio.com to provide our solution with Grid-In-Hand® Mobile Grid iOS app, and the idChamp RS2 NFC reader. Their customer service is fast, professional, and have always helped us to solve any problems. Here is a video showing how we have integrated out idChamp RS2 NFC reader into our valet service.
