Simply put, it will make more sense to have a washer/dryer combination machine. Yes, this will take longer to fully wash and dry the clothes, but this is a non-issue if the consumer was to load their clothes before going to bed. The machine will operate, and complete the cycle before the consumer wakes up. And since there is no transfer, the consumer can do other things such as sleeping at night than to micro manage a washer, and dryer.
In commercial applications where the machines are pay per use, the machine must accept the Kaldan National ID card as a payment source. Rather than paying for each time the machine is use, the laundromat will make one significant charge at one time at the close of business. This means there are no four $3.00 charges, and instead a single $12 charge will be applied to the account. Unlike consumer level machines, commercial machines will have separate washers and dryers – but all of the machines must be High Efficiency machines, and therefore will require a special detergent to use properly.
