It was recently found that all of the JSON strings used for Quick Kards were representing numbers as hexadecimal values. These are malformed json strings and work is under way to correct the issue. The plan is to make a sketch that will search for the malformed json strings and correct them and update the EEPROM on the Kard. If you need specific details contact tech.support@pontech.com.
Data format of I2C EEPROM which stores Kard Maker, Version, and Configuration.
