Gold-B059 2×100W Class D Digital Stereo Power Amplifier Board

Product Description

The S50 RFID Card features a slim, credit-card-sized form factor with a smooth PVC surface, making it ideal for custom identity printing using standard card printers. Internally, the card contains an etched antenna coil and a high-security CMOS chip. The memory is structured into 16 sectors, each protected by two sets of keys (Key A and Key B), allowing for multi-application use where different providers can securely store data on the same card without interference.

Key Features

• Collision Protection: Features an anti-collision algorithm that allows the reader to identify and process multiple cards simultaneously in the RF field.

• Secure Memory Structure: 1KB of memory is organized to support encrypted transactions, protecting against unauthorized data cloning.

• Printable Surface: The high-grade PVC finish is optimized for dye-sublimation printing of photos, logos, and barcodes.

• Passive Powering: No internal battery is required; the card draws all necessary operating power from the magnetic field generated by the reader.

• Fast Data Transfer: Supports data rates up to 106 kbit/s for rapid "tap-and-go" interactions.
