Concentration Risk Disclosure [Text Block] | Note 2 – Concentrations of credit risk Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We maintain our cash and cash equivalents with high-credit quality financial institutions. At October 31, 2024, we had cash and cash equivalent balances in excess of federally insured limits in the amount of approximately $668,000. Sales from each customer that were 10% or greater of net sales were as follows:
|  | October 31, |
|  | 2024 |  |  | 2023 |
Wireless provider |  |  | * |  |  |  | 10 | %
Distributor A |  |  | * |  |  |  | 10 | %
* Less than 10% For the year ended October 31, 2024, a wireless carrier customer and a distributor customer both accounted for less than 10% of total sales, and approximately 15% and 10% of the total net accounts receivable balance, respectively. For the year ended October 31, 2023, a different wireless carrier customer accounted for approximately 10% of total sales and had no accounts receivable. The same distributor customer accounted for less than 10% of sales and approximately 10% of total net accounts receivable, while another distributor customer accounted for approximately 10% of total sales and for 11% of the total net accounts receivable balance. Although the distributors have been on-going major customers of the Company and the wireless carrier is a newer customer to the Company, the written agreements with these customers do not have any minimum purchase obligations and they could stop buying our products at any time and for any reason. A reduction, delay, or cancellation of orders from these customers or the loss of these customers could significantly reduce our future revenues and profits.
