Data integrity of BIS M-4008-048-0xx-ST4
To increase data integrity, data transfer between the data carrier and compact processor as well as the storage device can be monitored using a check procedure.
A CRC_16 data check can be enabled for this via parameter configuration.
With the CRC_16 data check, a check code that allows the validity to be checked at any time is written to the data carrier.
A CRC_16 data check provides the following advantages:
– Data integrity even during the non-active phase (data carrier outside the R/W head).
– Shorter read time – page is read once.
