Sep 29, 2011 — by Jonathan Angel — from the LinuxDevices Archive

Viewat announced a handheld computer for point-of-sale (POS) applications, complete with integral smart card and magnetic stripe readers. The EFT-POS VPOS53 has a 1GHz Texas Instruments AM3715 processor, 320 x 240-pixel touchscreen, 256MB of RAM and 512MB of flash storage, plus both a GPS receiver and a GSM/GPRS/EDGE/CDMA cellular modem, according to the company.

Shenzhen, China-based Viewat lists the operating system for its modular EFT-POS VPOS53 handheld as being Windows CE 6.0 R3. A Sept. 28 press release by Texas Instruments (TI), however, touted the device as a reference platform that could be used to develop Linux- or Android-based POS systems.

In any case, the EFT-POS VPOS53 uses TI's 1GHz AM3715, a processor that includes both an ARM Cortex-A8 core and a OpenGL ES 2.0-based PowerVR SGX graphics accelerator. Viewat combines this with 256MB of RAM and 512MB of flash storage, plus a Mini SD expansion slot.

According to Viewat, the EFT-POS VPOS53 (above) includes a three-track MSR (magnetic stripe reader) as well as a smart card reader. Possible options include a three megapixel camera, a 1D/2D barcode scanner, and an RFID reader (Mifare A/B), the company adds.

The EFT-POS VPOS53 also comes with a thermal printer, employing paper rolls with an approximate width of 2.3 inches and a diameter of 1.2 inches, the company adds. And history will record exactly where receipts were printed, since the handheld is also said to include a GPS receiver based on the SiRF starIII chipset.

Viewat says the EFT-POS VPOS53 includes a Maxim MAXQ1850 cryptographic controller, ensuring secure storage of customer information. Pre-accredited by RFI Global, this controller already meets Payment Card Industry (PCI) security standards, which can save developers as much as a year of time, TI said in its related release.

Cited communications capabilities for the EFT-POS VPOS53, meanwhile, consist of 802.11b/g/n wireless networking, a GSM/GPRS/EDGE/CDMA cellular modem, and Bluetooth 2.0. A USB port and an RS232 port are also on board, Viewat adds.

According to Viewat, the EFT-POS VPOS53 has a 3.5-inch touchscreen (resistive, almost certainly) with a resolution of 320 x 240 pixels. The device also has 20 keys including a numeric keypad, plus a mono speaker and microphone.

The EFT-POS VPOS53 has a removable, 2000mAh battery whose expected life was not specified. It weighs 1.1 pounds and measures approximately 8.2 x 3.4 x 2.1 inches, says Viewat.
