Wireless pin pad in the front desk.

Hi,

I manage a small Hostel service near Toronto. We made a small alteration to the counter by building a guard in the counter front. Now, we have to place the pin pad over the counter guard for customers to enter their pin. So, I'm planning to buy a wireless pin pad for easy mobility. I am cautious about buying since I heard that these devices can get hung and suffers slow speed over the long run. I am presently using the fixed pin pad by VeriFone. I found online in this payment solutions company a wireless pin pad by NBS (http://www.versapay.com/payment-solutions/merchant-services/terminals/nb...). The specifications looks promising. If there is anyone using this product please share your opinions. I'd also appreciate other suggestions.

Thank you.
