7.8 Storage capacity of smart cards

The water credits are stored with four decimal digits on the smart
card. The maximum amount of water credits that can be stored on
a smart card is 420000.0000.
If a transfer or download of water credits leads to a value
exceeding 420000.0000, the transfer or download is rejected
completely.
7.9 Display of large amounts of water credits at the
AQtap
The AQtap can only display the first five digits of a value.
The maximum amount of water credits that can be transferred
between smart cards is therefore 99999, as no bigger value can
be selected.
If more than 99999 water credits are stored on a smart card, only
the first five digits will be displayed. The last digit is flashing to
indicate that the amount of water credits is not displayed
completely.
