EchoSat Communications

Clark has selected EchoSat as our preferred internet and satellite communications partner for stores processing on the Clark credit card network. You can connect to Clark via two methods.

First, you may connect via the internet. Stores with more than 2,500 transactions a month typically benefit from the much faster processing speed offered via an Internet connection (cable or DSL). Transacting via internet also has added security requirements that need to be addressed.

Second, you can always utilize a dial-up connection from any location with a dedicated phone line. Dial-up connections are the simplest, lowest cost way to transact any payment card. Equipment used for dial-up is usually a credit card terminal with few extra features.
