+>> "If someone took a sledgehammer, and slammed the meter they would not be able to take anything except for coins”
+===== Credit Card processing =====
+  *  Communication
+    *  The meters process CC transactions and give confirmation very quickly.
+  * <nowiki>**</nowiki> GSM
+  * <nowiki>**</nowiki> [[http://en.wikipedia.org/wiki/Zigbee|ZigBee]]
+  * <nowiki>***</nowiki> Wireless Mesh Networking
+  * <nowiki>**</nowiki> WiFi
+  * `PCI Compliant`
+    *  Does this mean data is encrypted and sent elsewhere for processing?
+  * <nowiki>**</nowiki>** Yes.** See quote from Frey above.
+    *  <s>Or does PCI compliant demand more from the meter?</s>
+    *  bV note: PCI compliant means that:
+  * <nowiki>**</nowiki> cardholder data, if stored, is stored encrypted
+  * <nowiki>**</nowiki> full magnetic stripe data as well as cvv code is not stored at all
+  * <nowiki>**</nowiki> cardholder data, if transmitted, is transmitted encrypted
