An embedded scan module that reads barcodes and cards from one board. The XL-E53-A carries a 640x480 CMOS engine with white LED illumination, decoding 1D codes, 2D codes and phone screen codes with 7 mil precision, 10-100 mm depth of field and 30% print contrast, at 360 roll, +/-60 pitch and +/-40 skew. Beyond barcodes it reads Mifare-compatible cards, ISO/IEC 14443A cards, NFC phones and second-generation ID card UIDs, with HTTP/HTTPS/TCP/UDP protocols for direct back-end integration. Interfaces cover USB, TTL, RS232, RS485 and Wiegand, with optional WIFI and Bluetooth; DC 5-24 V wide input draws 250 mA maximum and 200 mA working at 1.25 W peak. Automatic and motion-sense triggering, beeper feedback and config-barcode setup, 0-100,000 LUX ambient range and -20C to 60C operation. A compact 86.8x86.8x36 mm, 260 g body with mounting holes on both sides and a 30 cm cable fits self-service terminals, logistics, finance, transportation and healthcare equipment, as well as access control gates and ID verification terminals.
