Caution: Using a Wireless Phone Charger can damage your OneCard and your Phone!

If you are using a wireless charger, please make sure that your Deerfield OneCard is not between the phone and the charger pad while it is charging. Your OneCard contains a chip that can heat up and burn out. In extreme cases, this can cause the card to melt or catch fire. At a minimum, it will cause your card to stop working. To avoid damage to your phone and card, and to ensure your safety, please be sure to remove the card from the back of your phone while the phone is charging. Thank you!
