Besides its range of input/output interfaces, MSI's Hetis H81 has two COM ports to support use in business environments with POS systems, such as hotel registration desks and 24-hour convenience stores. These COM ports make it possible to link the PC up directly to a barcode reader, credit card reader or credit card terminal. It also provides security measures including a PC security lock to prevent theft and an additional chassis intrusion detection feature. The Hetis H81 can optionally also be equipped with a TPM security module to provide an even higher level of protection for personal data.
Even though Hetis H81 is a small system, two full-height and half-length PCI / PCI-E device can be installed.
