Coin dispensers are not wide spread currently in UAE where as people searching for coins are coins are increasing. This is a versatile AED Dirham dispenser which can work independently or combined with other vending solutions and dispensers. This is ideally suited at locations such as

    • Soft drink, coffee, chocolate type vending machines

It has built in intelligence to inform the status as LED display in the even of note not being accepted or not having enough Coins to dispense with. This stand alone ready-to-deploy coin dispenser can be fitted with existing Parking machines.

Typical Application – Change Dispenser with Vending machines

 Coin dispensers are presently put only at secure places like banks and shopping malls. But the requirement of change dispensers is mostly outside these secure places. If a company maintaining chain of coffee vending machines need to put coin dispenser, there should be some added benefit to do so as there is no direct benefit by maintaining a change dispenser.

Imagine a coffee vending machine or a soft drink vending machine in a crowded paid parking lot. People need change to pay their parking ticket. They don’t mind having a coffee if they can get change to pay their parking ticket. They can simply insert a 5 Dirham note and take a coffee or soft drink worth one/two dirham(s) and get 4or 3 Dirhams as change.

This is only an illustrative situation and this solution can be customized according to requirement.

SMS controlled Vending Solutions


This is a versatile SMS based application ideally suited for any type of remote terminals/dispensers that need to be controlled or monitored such as

  • Vending machines
  • ATMs
  • Ticketing machines

This solution uses a GSM modem board with SIM card slot and microcontroller based interface board. A remote dispenser fitted with this SMS auto attendant can send automatic SMS messages to predefined mobile number on certain events which can be programmed using easy-to-use front end software and the serial interface port. This solution uses an optical sensor to count the number items dispensed or sold and send preprogrammed SMS messages to a mobile or another SMS attendant.  Received SMS messages can be further interfaced to suitable software application for central monitoring and control. 

Typical Application - SMS controlled Soft drink Vending dispensers 

Generally, soft drink or any other coin operated dispensers located all over the city on roadsides, shopping malls or public places need to be refilled manually. Refilling staff need to travel to all those vending points periodically and check the available quantity and refill accordingly.  It may so happen that at some locations all items are sold and needs immediate refill or in some other locations there is no need to refill as enough items are still unsold.  In order to plan and reduce the refilling trips, such dispensers can be monitored and controlled with this SMS based solution.

SMS attendant can be fitted in such remote vending dispensers.  Say, there are 200 soft drink cans are filled and the SMS attendant is programmed to SMS when there is  90% of cans are sold leaving only 20 cans left. Optical sensor of SMS attendant will keep count of the cans dropping point and the moment 180 cans are sold, a programmable SMS message of maximum 50 characters is sent to a central mobile number or concerned refilling staff mobile. In case refilling does not happen and all the 100% cans are sold, another urgent message will be sent asking for immediate refill.  This will save time and effort by refilling
