Need to support the use of a wireless signature pad for registration.

We would like to use a wireless Topaz Signature pad that multiple computers can access and use. We have 4 people in our front office and any of those people could register a patient, but only 2 of them have signature pads and to purchase extra signature pads and have patients walk all over instead of the main desk seems ridiculous. TruBridge is saying that a wireless signature pad is not supported but that we can try one on our own to see if it works. I want them to support that function instead of us always having to take the chance.
