1. Frequency: Both ISO 14443 and ISO 15693 operate at 13.56 MHz.
2. Purpose: ISO 14443 is commonly used in contactless smart cards and NFC-enabled devices.
3. Read Range: ISO 14443 has a shorter read range of 7-15 cm (approximately 2.8-5.9 inches).
4. Data Transfer Rate: It offers a higher data transfer rate with a 106 kbps Baud rate.
5. Applications: ISO 14443 is suitable for financial transactions, access control, parking solutions, and attendance systems².

1. Purpose: ISO 15693 defines the communication protocol for RFID tags operating at 13.56 MHz.
2. Read Range: ISO 15693 provides an extended read range of up to 1 meter (approximately 3.3 feet).
3. Data Transfer Rate: It has a slower data rate with a 26 kbps Baud rate.
4. Applications: ISO 15693 is useful for applications like inventory management, asset tracking, and libraries¹⁵.

In summary, ISO 14443 is ideal for short-range applications like wireless payments, while ISO 15693 suits scenarios where longer read distances are necessary. 📡🔍🏷️¹²

ISO/IEC 15693-26:

1. Modulation Scheme: ISO/IEC 15693-26 uses a subcarrier frequency of 423.75 kHz.
2. Data Rate: The data rate for ISO/IEC 15693-26 is 26.48 kbps.
3. Application: This variant is commonly used in applications such as inventory management, asset tracking, and library systems.
4. Read Range: The read range is typically up to 1 meter (approximately 3.3 feet).

ISO/IEC 15693-53:

1. Modulation Scheme: ISO/IEC 15693-53 uses a subcarrier frequency of 847.5 kHz.
2. Data Rate: The data rate for ISO/IEC 15693-53 is 53.98 kbps.
3. Application: It is also used for inventory management, asset tracking, and similar applications.
4. Read Range: Similar to ISO/IEC 15693-26, the read range is up to 1 meter.

In summary, both variants are part of the ISO/IEC 15693 standard and share similar use cases. The main difference lies in their modulation frequencies and data rates. 📡🔍🏷️

This is the cheap version (the red board with 8 + 4 pin headers / connectors) you still can buy everywhere. Drawback: Only the 5V is exposed to the connector and not the 3.3V output. The board has to be modified to be usable with a 3.3V voltage source, e.g. by desoldering the voltage regulator and building wire bridge from 3.3V to the power pin on the connector (origially named 5V).

Bird ringing is the term used in the UK and in some other parts of Europe and the world. Bird banding is the term used in the US. Organised ringing efforts are called ringing or banding schemes, and the organisations that run them are ringing or banding authorities. (Birds are ringed rather than rung) Those who ring or band are known as ringers or banders, and they are typically active at ringing or banding stations.
