BIS L uses the low frequency (LF) 125 kHz and uses passive data carriers. These data carriers are writable/readable, designed for use in harsh environments and are very chemically resistant. With BIS L you can implement applications with special requirements cost-effectively. Small designs and versions with increased data security (additional check code) offer you a lot of flexibility.
