Notes“IPS Lead engineer Frey adds, “No data is stored on the meter. When you insert your credit card, it automatically goes to the bank, so your information is not stored anywhere online or in any sort of database.”
“If someone took a sledgehammer, and slammed the meter they would not be able to take anything except for coins”
