Not available for all devices now and future-proof
A checklist for all suppliers
FIREWALL
● Many send image/HTML5 of whole screen every time key is pressed = slow responses + high bandwidth needed
● Not good for fast/remote users on slow lines
● Not many support PF Keys
Does not use standard security and SSL encryption modules for end-to-end process at all times
● Not based on standard Microsoft Web-Services platform
● Was first written for a PC GUI then try to make available to view on mobile and can lose knowledge of underlying data fields and entry checks
● Proprietary software stack
● Harder to code, test, debug

1. Require application changes on server or client device = high risk on server and complex and risky on many varied and changing client devices.
2. This needs ongoing maintenance (coders) and code management on thousands of devices and takes a long time to test and deploy.
3. Not all user devices are supported day1 or into future.
4. Need a high level of Java or proprietary macro language in supplier modules
5. Use a method that sends lots of data to/from clienta. This needs higher network speeds (not always there for client)b. Significantly slows down fast data entry screensc. Puts more load on servers
6. Are not based on standard code and Web Services platforms supported by Microsoft
7. Do not use International standards and code for security and encryption
What do Most Terminal Emulators do Wrong?
copyright Flynet Limited 2014
● Short project setup
● Minimal risk to IT
● Maintain data integrity
● Use international standards for security and encryption
● Work on the widest range of current and future user devices
What Would a Good Terminal Emulator Have?
● Based entirely on worlds biggest Web-Services platform from Microsoft
● No code on user devices
● Lowest load on networks
● Fastest response times for users
● Minimum coding skills and workload required

Why the Flynet Viewer Offering is the Best
Central Application
TEServer
User DeviceAny device with a browser supporting HTML5
● Android● Windows ● Apple
Devices● Chrome
FIREWALL
● Only sends data/field changes as they happen
● Compressed data stream● Very good for fast/remote
users with low connection speeds
● Supports PF Keys
Uses standard security and SSL encryption modules for end-to-end process at all times
● Based on standard Microsoft Web-Services platform
● Builds standardised web services
● Can create an offline version of your data streams as a simulator to build and test user view against
● Built on the standard Microsoft Web Services stack
● Strong functions to code, test, debug
● No code on device
● Lower risk● No maintenance
or versions needed for device support
