Some suppliers offer second hand card machines as an option to customers. If you are considering going down this avenue, it is important to choose a reseller or buy directly from a manufacturer. In the event anything goes wrong you can deal with them directly to get a positive resolution. It is always advisable to check what warranties are included on second hand card machines, and how old the handsets are. Purchasing a second hand card machine offers a practical solution for start up businesses who may be working off a limited budget.
