This question may sound silly, but I am inquiring b/c I don't know a lot about electronics... In what situations do you use this device??? Just wanted a little more info about the usage of this device. Thank you!!
this is the square credit card reader.. you do need to install an app for it and if its been used or linked to another card I don't think you can use it. but id say look up square card reader before hand and see what your getting.
i figure if your on listia you should have access to the net.. hehe
