Binary Protocol
Aya developed a special binary protocol to exchange data between terminal device and central database. Due to small packet size and the elimination of data overheads, data transmitted are reduced to a minimum. As a result even networks with little throughput / stability issues deliver good results and communication cost is low.
Terminal Communication
The terminal either operates in an online or online/store & forward mode. The built-in SIM management connects the terminal to the central database with the strongest network being prioritized. On network unavailability an automatic failover process reconnects to the next strongest network.The terminal is permanently exchanging data with the central database.
Power Management
The terminal works on grid as well as battery power. A single battery charge lasts up to 10 days with the terminal on stand-by mode all the time except for transaction processing (typically few minutes per day). Aya thoroughly analysed all power critical elements involved in the communication process. Critical elements and Aya’s analysis to ensure stable and uninterrupted data communication are recognized as follows:
Dual SIM Cards
Aya redesigned online data transmission by allowing two active SIM cards to work simultaneously. Network management software monitors GSM field reception real time and allows for a seamless switching between network providers. In addition, location information retrieved is real time communicated to the central database which may assist in creating coverage & location profiles for future deployments.
Contactless Reader/Writer (RF-ID)
A built-in RFID chip reads personal ID's and data from customer RFID cards (MIFARE standard).
Heat & Humidity Resistance
All components including display (TFT or touch screen), thermal printer, keypad, main board and CPU have been adapted to conditions of high temperatures and humidity as common in Africa. Other than with standard payment terminals the keypad also is laminated and a one piece pad leaving no room for moist to enter and harm electronic components. The display is coated with UV reflecting materials that can withstand exposure to direct sun light. The thermal printer has been extensively tested for non-stop operation under high temperature conditions. Finally the terminal case itself has been tested for mistreatments like drops or other strong impacts.
Real Time Data Exchange & Over-the-Air Software Update
Solutions and respective terminal firmware are designed in a way that all future software updates (change of forms or revenue items additional applications etc.) are done on the central server. The new application is downloaded to and updated on all terminals over-the-air and is available immediately. Due to compression and small size of the applications, the transmission takes only seconds.

Critical elements and Aya’s analysis to ensure stable and uninterrupted data communication are recognized as follows:
- GCD Terminal – long lasting battery is able to bridge long power outages
- Network Transmission – several SIM Cards and provider failover
- Central Database – redundant, replicating & industrial UPS backup
- Mobile Networks BTS Power – mobile cell sites have generator backup throughout

Pre-Printed Thermal Paper
Aya supplies a custom design thermal paper together with the terminals and creates additional revenues from this service. An optional advertising space on each ticket can be used to communicate individual information to the users based on various select criteria (region, size, turnover, user type etc.). For instance changes in tax rates or Governmental news may be communicated this way. Alternatively space may be sold to 3rd parties interested in marketing their products to a predefined target clientele. |
