HandPunch readers take a three-dimensional reading of hand size and shape to verify user identity in less than one second. A special silver-based material, using BioCote silver antimicrobial technology, is embedded to create the HandPunch. This provides a hygienic finish that resists bacterial degradation and reduces bacteria levels on reader surfaces. The GT-400 reduces payroll costs, easily integrating into existing network infrastructures. The GT-400 comes standard with eight ATM-style programmable soft function keys, making dynamic labeling a snap. The HandPunch GT-400 features a large 3.8-inch QVGA display, which gives users the ability to access more information per screen than was ever possible with previous terminals.
