Integrated security manufacturer TDSi announced the launch of its new GARDiS Bluetooth Low Energy reader, which enables the authentication of security credentials from a compatible mobile device. This provides convenient, fully secure, cost-effective and safer contactless access for security operators and users. Research shows that 98% of security users view access control using a token or card as a constraint on their daily routine, whilst 68% would like to use their mobile smartphone to grant access.
